Original question.
The historical priorities were rest, relief of painful arthritis, and repeated examination for carditis; modern treatment also eradicates preceding streptococcal infection and prevents recurrences. In an 1865 account, the patient would be nursed in bed, the painful anatomical joints supported, drinks and tolerable nourishment supplied, and temperature, pulse, breathing and urine observed. Moist flannel applications and opium preparations were used for severe pain and sleeplessness. Alkaline salts were commonly prescribed under a theory that the disease involved an abnormal acid material; attempts to make the urine alkaline were a therapeutic practice, not proof that an acid caused the disease. There was already disagreement about the value of specific drugs and blistering agents. A contemporary critique describes these competing treatments and stresses the inadequacy of small uncontrolled case series.[ref]
Remarks on the treatment of acute rheumatism in the British Medical Journal (1865). 14 January, p. 31, ordinary management and criticism of blistering
The important complications are rheumatic carditis, including valvulitis and sometimes pericarditis, with possible heart failure; Sydenham's chorea is another manifestation. New dyspnoea, a changed heart murmur, chest pain, a pericardial friction rub, or signs of circulatory failure require reassessment rather than stronger treatment of the painful anatomical joint alone. Historically, local bleeding, Mercury and counterirritation were employed against supposed cardiac inflammation. Their historical use does not justify them now. A heart examination also matters when arthritis improves, because improvement of pain does not establish freedom from cardiac injury.[ref]
Clinical Guidance for Acute Rheumatic Fever by CDC. clinical manifestations: carditis, arthritis and chorea
Present management confirms the diagnosis and cardiac involvement with appropriate clinical criteria, electrocardiography and echocardiography. Penicillin or an appropriate alternative eradicates residual group A streptococci, even if the throat symptoms have resolved. An anti-inflammatory drug relieves arthritis; severe carditis, heart failure or disabling Sydenham's chorea needs specialist management. Fluid-retaining heart failure can require a diuretic with monitoring of renal function and electrolytes; treatment is selected according to haemodynamic findings. The 2025 guideline allows corticosteroids for selected severe carditis or pericarditis with effusion, under specialist care. Mild Sydenham's chorea may need only rest and a calm environment; greater functional impairment can justify carbamazepine or another carefully selected symptomatic medicine. These measures accompany, rather than replace, antibiotic prophylaxis. Secondary antibiotic prophylaxis reduces future attacks and further valve injury. Neither aspirin nor a later salicylate regimen should be presented as ordinary Oxford practice in 1865. These are historical explanations and general medical principles, not a treatment plan for an individual.[ref]

Original question.
What treatment would you ordinarily pursue in the Delirium of Typhus, and in the severe Diarrhœa of Typhoid Fever ?
The delirium of typhus calls for treatment of systemic illness and careful nursing; severe diarrhoea in typhoid fever additionally demands replacement of losses and vigilance for intestinal injury. These are different infections, despite the similar names.
For an 1865 description of typhus, provide a quiet, ventilated room, continuous attentive nursing, fluid and nourishment, mouth care, and protection from falls or wandering. Examine for retention of urine, constipation, chest complications and exhaustion. A restless sleepless patient was sometimes given a cautiously selected opium preparation; wine or other alcoholic stimulants were also employed in supposed exhaustion. Such practice was contested: contemporary observations warned that recovery after a drug did not establish that the drug had caused recovery. Sedation was especially questionable with deepening stupor or respiratory impairment. Routine depletion of an already prostrate patient was not a rational substitute for support.[ref]
Typhus Statistics of the Dundee Royal Infirmary, with Remarks by Thomas John Maclagan. 1865, discussion of stimulants, nursing and inference from recovery
Modern epidemic typhus is caused by Rickettsia prowazekii and requires prompt doxycycline, alongside management of hypoxia, dehydration, organ dysfunction and the precipitating infection. Testing should not postpone treatment when the clinical suspicion is strong. A low-stimulation environment and observation remain useful, while historical alcohol stimulation and indiscriminate opioid sedation are not disease-specific therapy. Control of the transmitting body lice is part of preventing further infection.[ref]
Clinical Overview of Epidemic Typhus by CDC. treatment, severe manifestations and transmission
In the historical treatment of severe typhoid diarrhoea, rest, readily tolerated nourishment and measured replacement of drinks were accompanied by attempts to quiet the bowel with opium, sometimes with an astringent such as chalk or a lead-containing preparation. These aimed at reducing stool frequency; they did not eliminate the cause. An apparent reduction of stools could conceal deterioration, and intestinal pain, distension, bleeding or collapse required renewed examination. Contemporary criticism of routine opium use in febrile bowel disease shows that this was never a uniformly established cure.[ref]
Opium in certain forms of fever and in diarrhoea and dysentery (1865 lecture). lecture read 1 December 1865, published February 1866, pp. 76–81; adverse effects and disputed indications
Today typhoid fever requires an effective antibiotic selected with travel history and local antimicrobial resistance in mind, then refined by bacterial culture and susceptibility results. Assess fluid balance, circulation, electrolytes and kidney function, using oral or intravenous replacement as severity requires. Gastrointestinal bleeding, increasing abdominal tenderness, guarding, distension, shock or a sudden change in condition can indicate intestinal perforation or other severe complications and need urgent hospital assessment. Historical lead preparations are toxic; suppressing diarrhoea is not a substitute for treating the infection and its complications.[ref]

Original question.
When are topical applications to the Pharynx, or Larynx, desirable? How do you apply them, and with what object? What drugs are used for the purpose, and in what doses ?
Local treatment is useful when there is an accessible lesion or a defined symptom to relieve; its concentration, delivered quantity and route must be specified separately. Historical indications included chronic pharyngitis with excessive secretion, ulceration, enlarged or unhealthy tonsillar surfaces, and some forms of chronic laryngitis. The intended effects were cleansing, soothing, reducing secretion, or cauterising a circumscribed unhealthy surface. Merely having a sore throat was not sufficient reason for a caustic application.
The accessible pharynx could be treated by a gargle, a wash, a lozenge, or a carefully directed brush or sponge. A gargle does not reliably medicate the larynx: during normal swallowing the entrance is protected, and aspiration is an unwanted event. For laryngeal painting, the period apparatus included a light source, reflector, small warmed laryngeal mirror and a suitably bent brush. Illumination and the mirror image allowed inspection of the lesion and guidance of the instrument, instead of blind probing. A small measured loading reduced uncontrolled flow into the airway. An atomiser instead broke liquid into droplets with a jet of air or steam; the concentration in its reservoir was not the amount retained by the patient. A contemporary review discusses brushes, mirrors, caustic holders and the limitations of spraying caustic solutions.[ref]
Recent Works on the Laryngoscope (1865 review). pp. 310–319, local treatment and equipment
For a numerical period example, the 1865 account of medicated inhalation gives silver nitrate, 3–5 grains, sometimes 10 grains, per Imperial fluid ounce of distilled water. These are historical reservoir concentrations, approximately 0.7–2.3 percent mass per volume, not oral doses and not modern recommendations for inhaling a corrosive. Other concentrations in the same 1865 account, each per fluid ounce of water, are tannic acid, 3–10 grains; alum, 4–15 grains; zinc sulfate, 1/2–5 grains; and opium tincture, 1–10 minims. The first three were intended chiefly as local astringent applications, and the last as a soothing or narcotic application. These are reports of historical practice, including hazardous applications, rather than evidence that atomising these drugs is beneficial or safe today.[ref]
Medicated inhalation in the Retrospect of Medicine (1865). vol. 52, pp. 102–106, especially p. 105, numbered list of drugs and silver-nitrate strengths
Direct historical cauterisation used still stronger silver nitrate solutions or the solid salt for selected ulcers and growth bases. A contemporary review records disagreement over aggressive treatment and reports a recommendation of 40 grains per fluid ounce in one of the works reviewed. That disagreement is part of the answer: 40 grains per ounce for local painting must not be confused with a dilute gargle, an inhalation concentration or a swallowed dose. For a less destructive mode of local medication, the period dosage table lists one to four or more tannic acid lozenges, illustrating again the distinction between strength per item and the number administered.[ref]
Recent Works on the Laryngoscope (1865 review). discussion of strong silver solutions and missing dose information
[ref]Modern uncomplicated acute sore throat usually receives symptom relief, adequate drinking, and selective antibiotic treatment when indicated by the assessed cause and severity. Medicated lozenges can give a small reduction in pain in adults; that modest benefit does not validate the historical corrosive sprays. Persistent hoarseness, a focal ulcer or a suspected growth requires diagnosis rather than repeated empirical painting. Stridor, difficulty managing secretions or respiratory distress raises an airway problem, for which irritating instrumentation can be hazardous. Local treatment of a syphilitic or other specific lesion cannot replace systemic treatment of its cause.[ref]

State the most usual modes of treating Syphilis in its several stages or varieties.
In 1865 Mercury was the principal systemic remedy for early constitutional syphilis, while potassium iodide was especially associated with later destructive lesions; neither is an acceptable substitute for modern penicillin therapy. Historical classifications depended chiefly on clinical appearance, before identification of Treponema pallidum and modern serology.
For a primary indurated chancre, period treatment combined cleanliness, protection from friction and irritant discharges, and, in mercurial practice, a prolonged course of a Mercury preparation. Administration could be by mouth or by rubbing an ointment into the skin; some practitioners used fumigation. Local cauterisation of a sore could not be assumed to remove infection already spread beyond it. Painful soft sores and suppurating groin swellings were often discussed among venereal diseases, but modern chancroid is distinct from syphilis; an 1865 “variety” cannot automatically be assigned the same cause or treatment.[ref]
Health of the Navy: Home Station report (1864). discussion of infecting sores, soft sores, buboes, mercurial and non-mercurial practice
In secondary disease, with generalised eruptions and mucosal lesions, Mercury was used in carefully watched courses, with food, hygiene and local care. Blue pill, grey powder and other mercurial compounds were alternative forms, not interchangeable quantities. Stomatitis, excessive salivation, bowel disturbance and constitutional deterioration were reasons to interrupt treatment, not desirable signs of cure. Relapse after apparent healing was recognised. For later gummatous syphilis, painful periosteal swellings, ulceration and some nervous manifestations, potassium iodide, sometimes combined with a mercurial, was a characteristic period choice. Apparent symptomatic improvement did not demonstrate eradication of the infection.[ref]

[ref]Clinical Commentaries on late syphilis in the British Medical Journal (1864). 3 September, p. 263, late tertiary lesions and iodide practice
Congenital disease also received mercurial treatment in the period, together with attention to feeding and the mother. That history must be separated from present management: congenital syphilis results from maternal infection, not an inherited constitutional taint. Maternal treatment, infant examination and laboratory evaluation determine modern management; an affected infant can require a full course of parenteral penicillin even without obvious external lesions.[ref]
Modern early acquired syphilis, including primary, secondary and early latent disease, is ordinarily treated with benzathine penicillin G, 2.4 million units intramuscularly once in adults. Late latent disease or disease of unknown duration ordinarily requires three weekly 2.4-million-unit injections. Neurosyphilis, ocular disease and otic disease require a regimen with appropriate tissue penetration, ordinarily aqueous crystalline penicillin G, 18–24 million units per day intravenously for 10–14 days, rather than the single early-disease injection. Pregnancy, allergy, congenital disease and other special circumstances need the corresponding specialist pathway. Clinical and quantitative serological follow-up, partner management and assessment for coexisting infections are part of treatment. The stage labels guide management, but nervous, ocular or auditory involvement can occur at more than one stage.[ref]

Original question.
Urine microscopy can identify the kind and possible site of urinary disease, directing further investigation and cause-specific treatment; a sediment finding alone is seldom a prescription. This is a general methods question. No particular specimen, microscopic field or patient result is supplied.
Examine a fresh, properly collected sample, noting collection and storage conditions. After gentle mixing, examine a standardised sediment with a microscope: a low-power objective helps find urinary casts, while higher power characterises cells, bacteria and crystals. A centrifuge concentrates sediment when that method is used, but excessive delay or unsuitable processing can destroy cells and casts or generate crystals after collection. Interpret findings with symptoms, urine chemistry and kidney function; a dirty container or vaginal contamination can otherwise mimic urinary disease.[ref]
EFLM European Urinalysis Guideline (2023). urine particles, specimen stability and microscopy procedures
Red blood cells indicate haematuria, whose source may be anywhere along the tract. Red blood cell casts or convincing dysmorphic red blood cells support a glomerular origin and justify assessment for glomerulonephritis, including renal function, proteinuria and appropriate referral. They do not establish a particular immunological cause. Isomorphic red blood cells with pain may suggest a stone; persistent unexplained haematuria also requires assessment for other urinary pathology. A historically tempting order to give an astringent would not address these different mechanisms.[ref]
Microhematuria guideline by AUA and SUFU (2025). initial evaluation, suspected medical renal disease and risk-based urinary evaluation
Many white blood cells, with compatible symptoms and bacteria, support urinary tract infection; obtain a suitable bacterial culture when indicated and select an antibiotic according to the clinical syndrome and susceptibility. Contamination or asymptomatic bacteriuria is not equivalent to symptomatic infection. White blood cell casts favour an intrarenal process such as pyelonephritis or interstitial nephritis, so the treatment cannot be inferred from pus alone. Numerous squamous epithelial cells instead raise concern about collection quality.[ref]
Renal tubular epithelial cells and granular casts can support tubular injury; fatty elements together with marked proteinuria suggest a nephrotic process. These findings direct assessment of kidney disease, fluid balance and potentially nephrotoxic exposures. A few hyaline casts may occur without a specific kidney disease. Casts are moulds formed within renal tubules; that origin is why they can localise a finding more effectively than free cells.[ref]
Urinary Casts by Merck Manual. table, tubular, granular, fatty and hyaline casts
Urinary crystals must be interpreted with urine acidity, concentration and the time after collection. Uric acid or calcium oxalate crystals can suggest a stone-forming environment but do not prove an obstructing stone or justify an unrestricted alkali prescription. Hexagonal cystine crystals raise a different metabolic question. Infection-associated phosphate stones require attention to the associated infection as well as stone management. Modern decisions combine stone analysis, imaging and metabolic assessment; hydration, urinary alkalinisation or other measures depend on the confirmed disorder. Microscopy does not by itself measure glucose, albumin loss or renal filtration, so these require separate tests.[ref]

Original question.
Enumerate the counter irritants contained in the British Pharmacopœia, and state under what circumstances you would have recourse to the use of each.
The 1864 British Pharmacopoeia supplied mild rubefacients, blistering preparations and agents producing pustulation; these different degrees of injury were grouped under historical counterirritation. Redness of the skin demonstrates a local effect, not removal of inflammation from a distant organ. The following enumeration uses the preparations current for the 1865 examination.
- Mustard, as Sinapis and Cataplasma Sinapis, was a rapidly acting rubefacient, used historically for transient painful or spasmodic conditions and as a supposed revulsive application in internal disease. Its duration had to be limited because prolonged contact caused a burn. The later compound mustard liniment and mustard paper should not be silently inserted into this 1864 list.[ref]The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865). Cruciferae, mustard and its official cataplasm
- Ammonia liniment, Linimentum Ammoniae, and the ammoniacal Linimentum Camphorae Compositum gave relatively prompt irritation. They were used for superficial muscular or rheumatic pains when a short rubefacient effect was desired. Simple camphor liniment and soap liniment were milder stimulating embrocations for stiff painful parts; the compound camphor liniment owed much of its greater irritation to Ammonia.[ref]The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865). strong solution of ammonia; Lauraceae, camphor preparations
- Turpentine, in Linimentum Terebinthinae or Linimentum Terebinthinae Aceticum, and in the official turpentine ointment, was used as a stimulating application. Historical indications included muscular pain, neuralgic pain and chest or abdominal applications intended to act on deeper disease. The acetic preparation was the more irritating form. This does not establish that either could cure pneumonia or intestinal disease.[ref]The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865). Coniferae, turpentine liniments and ointment
- Capsicum and its tincture supplied a pungent local stimulant, used in diluted embrocations for chronic painful conditions. Burgundy pitch, chiefly Emplastrum Picis, supplied milder sustained stimulation, historically chosen for chronic chest, back or rheumatic discomfort. An adhesive plaster could itself cause dermatitis.[ref]The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865). Solanaceae, capsicum; Coniferae continued, pitch plaster
- Cantharides supplied Emplastrum Cantharidis, Linimentum Cantharidis, Emplastrum Calefaciens and Unguentum Cantharidis. The warming plaster aimed at a milder prolonged effect; the ordinary plaster and liniment were vesicants, while the ointment could maintain an already blistered surface. Period indications included pleurisy, pericarditis, chronic painful anatomical joints and neuralgia. These were intended remote effects, not demonstrated cures. The 1864 name is Linimentum Cantharidis; its later renaming as Liquor Epispasticus must not erase the edition difference. Cantharides vinegar and official blistering paper belong to the later additions, rather than this list.[ref]The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865). Coleoptera, British preparations and distinction from the old London vinegar[ref]British Pharmacopoeia by the General Medical Council (1867). prefatory lists of additions and altered names, pp. xvii–xx
- Iodine, as Linimentum Iodi, Tinctura Iodi and Unguentum Iodi Compositum, was painted or rubbed over chronic swellings, indurations and diseased anatomical joints. The strong liniment could blister; the intended historical effect was alteration of local action or promotion of absorption. Such an indication was not equivalent to proof that a swelling was benign or that it would resolve.[ref]The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865). iodine, official preparations and external therapeutic uses
- Croton oil, especially Linimentum Crotonis, and tartar emetic, in Unguentum Antimonii Tartarati, produced more persistent irritation and a pustular eruption. They were employed for prolonged counterirritation in chronic pulmonary or other deep-seated complaints when a temporary rubefacient was considered insufficient. Ulceration, scarring and systemic toxicity were substantial disadvantages, not evidence of effective elimination of disease.[ref]The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865). Euphorbiaceae, croton liniment; tartarated antimony and its ointment
Other official substances could destroy tissue, but a caustic used to destroy a particular lesion is conceptually different from a counterirritant applied to influence another site. Likewise belladonna and aconite applications were principally intended to relieve pain, not simply to create a competing skin inflammation. Modern treatment should address the diagnosed condition; a historical claim of revulsion cannot justify blistering over a diseased heart or lung. The period literature itself recognised absorption, urinary irritation and sloughing from cantharides. No present-day use of a particular regulated skin preparation makes these broad historical indications valid.[ref]

Original question.
Describe the various modes in which water may be used externally as a Therapeutical agent, and name the cases to which each is suited.
External water treatment can clean, transfer heat, provide moisture and apply mechanical pressure; the useful method depends on the object, not on a general claim that water expels disease. Historical classifications distinguished general and local bathing, cold and warm applications, affusion, showers, compresses, packing and vapour baths.
Cold applications included sponging, pouring water over the body, immersion, a local wet compress and a cold shower or douche. A renewed wet cloth removes heat by contact and evaporation; a wrapping allowed to warm and then covered is a different intervention. In 1865 these methods were used for febrile heat, local pain or swelling, and sometimes to obtain a supposed stimulating reaction in chronic debility. A cold douche also adds mechanical impact and an abrupt circulatory stimulus. Historical wet-sheet packing enclosed the body in a wet sheet with outer coverings and was either renewed to sustain cooling or left to warm. The contemporary description distinguishes these uses; the claims about stimulation and cure are historical claims.[ref]
Hydrotherapy in the Edinburgh Medical Journal (1865 review). wet-sheet packing, renewed cooling compresses and warming compresses
Tepid and warm immersion, a warm local bath or sitz bath, and warm moist fomentations were used to soothe painful or spasmodic conditions, support cleansing and soften crusts or secretions. Local applications avoid heating the whole body. The apparatus might be a bath, basin, irrigating vessel or repeatedly renewed cloth; a warm moist dressing must not become a source of sustained scalding. Historically, hot immersion and vapour baths were also used to induce sweating in rheumatic complaints and supposed retention of harmful material. Heat-induced sweating is real, but removal of a disease-specific poison by that route is a separate claim requiring evidence. Showering and douching similarly cannot be treated as dose-equivalent to quiet immersion.[ref]
The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865). water and mineral waters, external thermal-bath uses
Current examples show why the distinction matters. Heatstroke requires rapid cooling and emergency care: cold-water immersion or other active cooling is used to reduce dangerous body temperature, not to provoke a later “reaction”. In contrast, routine tepid sponging is not recommended for fever in children under five. Febrile thermoregulation can provoke shivering and distress with external cooling, so the treatment of ordinary fever should not be inferred from the management of hyperthermia.[ref]
Heat-related Illnesses by CDC and NIOSH. heatstroke, emergency response and rapid cooling
[ref]For a thermal burn, current first aid uses cool running water for 20 minutes, with the rest of the person kept warm; ice or an ice-water application is not the appropriate substitute. Cleansing or irrigation has a further purpose independent of temperature: physically removing contamination, with the fluid and technique chosen for the tissue and injury. A steam application to the face is not a harmless version of warm bathing: spilled hot water and steam cause scalds. The historical use of inhalation therefore does not validate leaning over boiling water as a general respiratory treatment. These examples specify an actual therapeutic objective without endorsing the broad claims of nineteenth-century hydropathy.[ref]

Original question.
What are the doses of the Pharmacopœial preparations of Arsenic, Copper, Opium, Belladonna, Strychnia, and Cinchona ?
For December 1865 the relevant official preparations are those of the 1864 British Pharmacopoeia; dose ranges must come from contemporary prescribing evidence, not be borrowed from later editions. The first edition specified identities and preparations without supplying a universal clinical dose for every article. The following are historical adult quantities from The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865), using its British entries rather than bracketed United States formulas. They are not current prescribing instructions or established safe limits. “Grain” is a unit of mass; “minim”, fluid drachm and fluid ounce are units of volume. One Imperial fluid drachm contains 60 minims, and one fluid ounce contains eight fluid drachms. A minim is not an arbitrary drop.[ref]
The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865). introduction, British weights and measures; posological table
For arsenic, distinguish the elemental substance from its medicinal compounds. The relevant series comprises Acidum Arseniosum, Liquor Arsenicalis, Sodae Arsenias, Liquor Sodae Arseniatis and Ferri Arsenias. The contemporary ranges are arsenic trioxide about 1/60–1/12 grain; arsenical solution 2–5 minims, occasionally 10; crystalline sodium arsenate 1/12–1/2 grain, or its dried salt 1/20–1/4 grain; its official solution 5–30 minims; ferrous arsenate 1/10–1/8 grain. Hydrated and dried salts cannot be exchanged grain for grain. The two official arsenical solutions each contain four grains of their specified ingredient per fluid ounce, but the ingredients are different. The solution of arsenic and mercury discussed alongside them was non-official, and Liquor Arsenici Hydrochloricus was an addition in 1867: neither belongs in an unqualified list of 1864 preparations.[ref]
The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865). arsenious acid, sodium arsenate, ferrous arsenate; posological table
[ref]For copper, the medicinal article is purified Cupri Sulphas, copper sulfate: 1/4–2 grains as a historical astringent or tonic, 5–8 grains as a historical emetic. An external solution was described as 1–10 grains or more per fluid ounce, depending on the intended local action. The anhydrous test reagent and copper compounds listed among analytical materials are not additional ordinary internal preparations. Neither the historical emetic use nor an external concentration authorises modern oral use.[ref]
The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865). purified copper sulfate, medicinal doses and distinction from analytical copper salts
For opium, the contemporary monograph gives powdered opium and Extractum Opii, 1/4–3 grains or more; Extractum Opii Liquidum, Tinctura Opii and Vinum Opii, 4–40 minims or more; Tinctura Camphorae cum Opio, 1–2 fluid drachms. These are the author's reported ranges, not maxima. His summary table differs, listing 3–30 minims for liquid extract and 1/2–4 grains for powdered opium; that internal variation should remain visible rather than being converted into an invented single official limit.[ref]
The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865). Action of the other constituents of opium, Dose; compare Posological table
The compound oral opium preparations require their own quantities: Pilula Opii, 2 1/2 grains upwards; Pilula Plumbi cum Opio, 4–8 grains; Pulvis Cretae Aromaticus cum Opio, 10–60 grains; Pulvis Ipecacuanhae cum Opio, a reference quantity of 5 grains upwards; Pulvis Kino cum Opio, 10 grains upwards; Trochisci Opii, one to four lozenges. In the same order, the pill masses and powders contain approximately one part opium in 5, 8, 40, 10 and 20; each opium lozenge contains 1/10 grain. “Upwards” in the historical source does not establish a safe upper boundary: the required opium content, other ingredients and circumstances controlled the quantity. The lead-containing pill has an additional toxic constituent. Enema Opii supplies about one grain of opium in the official two-fluid-ounce enema; this is a rectal preparation, not an oral measure.[ref]
The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865). opium preparations; posological table and table of ingredient proportions
The external opium preparations, Emplastrum Opii, Linimentum Opii and Unguentum Gallae cum Opio, have no ordinary swallowed dose. For completeness the official isolated alkaloid series was Morphiae Hydrochloras, Liquor Morphiae Hydrochloratis, Suppositoria Morphiae, Trochisci Morphiae and Trochisci Morphiae et Ipecacuanhae. The reported historical quantities are morphine hydrochloride, 1/8–1 grain; its solution, 20 minims to two fluid drachms in the monograph; one suppository containing 1/4 grain; either kind of morphine lozenge, one to four, each containing 1/36 grain. The summary table gives a narrower upper quantity of one fluid drachm for the solution. These large historical ranges must not be interpreted as safe for a person without opioid tolerance. The solution contains four grains per fluid ounce. Neither a morphine-acetate preparation added later nor a non-official compound confection should be substituted for this 1864 series.[ref]

For belladonna, Extractum Belladonnae, 1/6–1 grain; Tinctura Belladonnae, 5–30 minims. Emplastrum Belladonnae, Linimentum Belladonnae and Unguentum Belladonnae are external preparations, not additional oral doses. The associated Atropia, Liquor Atropiae and Unguentum Atropiae likewise require their route to be stated: this author specifically discourages routine internal atropine administration and describes ophthalmic use of the solution. Its strength is four grains per fluid ounce; the ointment contains eight grains per ounce. These are historical formulation strengths, not a modern eye-drop or oral prescription. The atropine-sulfate series introduced in 1867 is not the 1864 series.[ref]
The Essentials of Materia Medica and Therapeutics by Alfred Baring Garrod (1865). Solanaceae and continuation; Belladonna and Atropia in the ingredient table
For Strychnia, strychnine, the historical range was 1/32–1/8 grain; Liquor Strychniae, 5–15 minims, the solution containing four grains per fluid ounce. If the botanical preparations yielding the alkaloid are included, powdered nux vomica, 1–3 grains; Extractum Nucis Vomicae, 1/4–2 grains; Tinctura Nucis Vomicae, 10–30 minims. The American editor already warned that the two-grain extract quantity was very large and that more than half a grain commonly risked adverse effects. Keeping that qualification is more faithful than presenting the printed upper range as routine or safe.[ref]

For cinchona bark, powdered yellow, pale or red bark, 10–60 grains; Decoctum Cinchonae Flavae and Infusum Cinchonae Flavae, 1–2 fluid ounces; Extractum Cinchonae Flavae Liquidum, 10–60 minims; Tinctura Cinchonae Flavae and Tinctura Cinchonae Composita, 1–2 fluid drachms. The associated Tinctura Quiniae Composita was given at 1–2 fluid drachms. The isolated official quinine sulfate, Quiniae Sulphas, was listed at 1–10 grains, with larger quantities discussed for particular intermittent fevers. Ferri et Quiniae Citras, the official iron-and-quinine preparation, was listed at 5–20 grains. Other cinchona alkaloids discussed as possible remedies do not thereby become official preparations. Strength in bark equivalents also does not guarantee a fixed amount of extracted quinine.[ref]

These figures answer a historical materia medica question. Current drug safety requires the exact modern product, route, indication and patient factors; poisonous nineteenth-century “tonics” and emetics are not revived by accurate transcription of their period doses. Strychnine can cause severe painful convulsions; opioids can depress breathing; and inorganic arsenic is a toxic and carcinogenic exposure. Those facts undermine any reading of the historical numbers as a self-treatment schedule.[ref]
