Use a documented examination of the whole body and lungs, with a lung flotation test as corroboration rather than an infallible verdict. Previous breathing, live birth and death by drowning are three different propositions. The question asks how to investigate; it does not supply a body on which to report an actual positive or negative result.

First establish the apparent age and development of the child, the condition of the remains and any evidence about birth, recovery from the water or attempted resuscitation. If the child is evidently older, independent evidence of survival after birth may settle much of the issue. In a newly born child, the forensic problem is harder. Record decomposition, injuries and any manipulation before opening the chest. Avoid inflating or unnecessarily compressing the lungs before their original state has been documented.

On opening the chest, observe the position, extent, colour and consistency of the lungs. Unexpanded newborn lungs are generally compact and do not fill the chest as expanded lungs do. Aerated regions may be more expanded, spongy and crepitant. Cut surfaces may show small air bubbles. These observations support a judgement about aeration, but disease, collapse and decomposition complicate their interpretation. Examine both sides and different regions, because a few breaths may expand only part of the lungs.

For the historical lung flotation test, place the removed thoracic organs in water, then examine the lungs separately, their lobes and representative small pieces. Record what floats and what sinks at each stage, using a vessel deep enough for free flotation. The physical principle is reduction of average density by retained gas. Testing only a whole organ can miss a small aerated region. The test belongs to the pre-1865 forensic toolkit: the contemporary encyclopedia discussed lung flotation and explicitly recognized both artificial inflation and putrefaction as alternative explanations for floating.^[ref]

There are two main classes of error. Floating can result from gas introduced by attempted artificial respiration or generated after death, so it does not by itself prove spontaneous breathing. Look for decomposition elsewhere and compare the distribution of gas in the lungs and other organs. A floating piece of liver can support the suspicion of generalized gas formation, but a sinking comparison organ does not guarantee that all pulmonary gas arose during life. Historical claims that squeezing a fragment always distinguishes breathed air from artificially introduced air were too confident; compression is not a decisive separator of the causes of aeration.^[ref]

Sinking does not establish that the child never breathed. A few ineffective breaths, limited expansion, or heavy, fluid-filled or diseased lung tissue can leave the material tested denser than water. A later prospective autopsy study reported four false-negative tests in which lungs sank despite prior life reported by medical staff. That observation demonstrates why a negative result cannot stand alone; the study's overall performance in its own material is not a universal accuracy guarantee for decomposed bodies recovered from water.^[ref]

Use the whole examination and independent evidence to reach a qualified conclusion. Feeding, healing changes or reliable observations of the living child may support survival, but they are different evidence from lung aeration. A child can show signs of life without establishing effective breathing, and an inflated lung does not establish a particular cause of death. Immersion may have occurred before or after death; neither flotation nor the body's location alone proves drowning. Where decomposition or attempted resuscitation prevents a confident distinction, report the limit rather than manufacture certainty.

Opium poisoning characteristically causes progressive unconsciousness with dangerously depressed breathing; acute poisoning by soluble antimony compounds chiefly causes violent gastrointestinal illness and collapse. Each requires its own differential diagnosis and treatment. The historical discussion below describes an 1866 examination answer; the present medical explanation is distinguished explicitly.

With opium poisoning, early drowsiness progresses to deep coma. Pupillary constriction, slow shallow breathing, snoring or gurgling breathing, a limp body and cyanosis are important findings. Failure to wake the person, together with depressed breathing, is more significant than apparent peaceful sleep. The pupils need not remain small in advanced hypoxia, and a single sign cannot establish the diagnosis.^[ref]

An 1866 practitioner would seek to remove unabsorbed opium by a stomach pump or an emetic, try to rouse the patient, and sustain breathing by artificial respiration. The contemporary encyclopedia explicitly states that no antidote was known. For antimony, the same source recommended a decoction of Peruvian bark; such tannin-containing preparations belong to the history of attempts to render the poison insoluble, not to a demonstrated modern antidote regimen.^[ref]

In present practice the immediate priorities in severe opioid poisoning are an open airway, adequate pulmonary ventilation and urgent medical support, together with naloxone to reverse the opioid effect. Continued observation is needed because respiratory depression can return after reversal. Pouring liquids into the mouth or inducing vomiting can cause aspiration; efforts to rouse the person must not delay effective breathing support.^[ref][ref]

The principal mimics of opium poisoning include alcohol intoxication, a stroke formerly described as “apoplexy”, and other causes of coma, such as hypoglycaemia or uraemia. Establish the sequence of symptoms and exposure, examine breathing and the pupils, and look for focal neurological signs. Odour of alcohol does not exclude a second poison or a stroke. Modern testing of blood glucose and appropriate neurological assessment complement the exposure history; urgent treatment of failed breathing must not await a chemical identification.

For antimony poisoning, the important period exposure is tartar emetic, or antimony potassium tartrate. Acute ingestion may cause nausea, repeated vomiting, abdominal pain, profuse diarrhoea, thirst, weakness and circulatory collapse. Loss of water and electrolytes compounds the toxicity. Present knowledge also recognizes serious cardiac effects; repeated exposure may produce continuing gastrointestinal illness and weakness rather than one dramatic attack. The chemical form matters: these findings should not be generalized to every exposure to metallic antimony.^[ref]

The closest clinical confusions are cholera, severe gastroenteritis, and poisoning by other irritants, especially arsenic. Recurrent attacks associated with particular food or medicine, persistence outside an outbreak, and chemical examination of vomit, excreta and suspected preparations help distinguish them. These are clues for investigation, not grounds for declaring a particular person guilty.

Modern management of antimony poisoning stops further exposure, supports breathing and blood circulation, replaces fluid and electrolyte losses, and monitors cardiac arrhythmias and organ function. A specialist determines whether decontamination or chelation is appropriate. The institutional monograph records sparse human evidence for chelation; it does not justify presenting a tannin drink or any chelator as a certain cure. It is a later, explicitly dated toxicological comparison, not the treatment available to the 1866 candidate.^[ref]

Seek evidence of penetration and evidence bearing on violence separately; neither a finding nor its absence can by itself determine consent or establish the whole felony. Twelve hours is a reason to examine and preserve evidence promptly, not a guarantee that diagnostic traces will be present.

For the historical legal element, use the original Offences against the Person Act 1861. Section 63 made carnal knowledge complete upon proof of penetration without requiring proof of emission of seed. Thus absence of semen cannot defeat proof of the penetration element, while the presence of semen does not by itself establish that element or identify an offence. Section 48 treated rape as a felony; §63 specifies the narrower evidential point asked about here.^[ref]

Obtain permission for the examination and each specimen, record the account in the woman's own terms, and note the reported timing, pain, bleeding, washing and changes of clothes. Ask about other recent sexual contact only insofar as it affects interpretation of a trace. Record observations independently of the allegation, preserving clothing and samples with their identities and collection sites. A medical examination should also address injuries and health needs; its purpose is not merely production of evidence.

For evidence of recent penetration, inspect the vulva, vaginal entrance and, where appropriate, the vagina for fresh abrasions, bruising, tears, swelling, tenderness or bleeding. Describe the location and appearance rather than calling an injury a “rape mark”. Collect any relevant fluid and stained clothing. An 1866 examination could use microscopy to look for sperm; modern analysis may add validated semen tests and DNA profiling. Neither retained sperm nor an injury can precisely date the event to twelve hours previously or prove who performed it without additional evidence. Conversely, washing, lack of ejaculation or loss of a sample may leave no detectable trace.^[ref]

Do not infer prior sexual history from vaginal laxity or the appearance of the hymen. A fresh injury can be documented, but an uninjured or previously altered hymen cannot prove or disprove the particular alleged penetration. Current authoritative guidance expressly rejects “virginity testing” as a scientifically valid inference about intercourse.^[ref]

For evidence bearing on force and non-consent, examine the whole body for abrasions, bruises, torn clothing, restraint marks and injuries of the thighs, wrists, arms, face or neck. Record any account of threats, overpowering, loss of consciousness or inability to resist. Injuries may corroborate an account of violence, but can have other causes; their absence does not establish agreement. A frightened or incapacitated person may not struggle, and penetration can occur without visible injury. Even apparently precise examination findings must be interpreted alongside the history and other evidence.^[ref]

Some nineteenth-century medico-legal writing demanded continuing resistance as evidence of non-consent. That was a historical assumption, not a biological test of whether consent was withheld.^[ref] The medical witness should state what was observed and how strongly it supports the account; the tribunal determines the legal conclusion. No universal combination of semen, hymenal findings and bruises can “legally establish” all the elements from the examination alone.

English law in 1867 fixed no maximum period of proved non-intercourse compatible with legitimacy; an exceptional interval had to be assessed on the evidence of possible gestation in the particular case. The relevant interval runs from the last possible intercourse between the spouses to the child's birth. Proof of subsequent non-intercourse establishes that interval; it does not itself establish how long pregnancy could have lasted.

The contemporary eighth edition of the Encyclopædia Britannica, published in 1853–1860, expressly distinguished the English position from numerical limits in continental codes. Its article on forensic medicine states: “The law of England at present has no definite limit”; it then says that a case beyond the usual term would go to a jury. This directly answers the legal question: there was no prescribed number of days that resolved every case. Medical evidence about the credibility of the claimed gestation informed the tribunal's decision about the child's status.^[ref]

To see what “consistent” means, distinguish the ordinary duration of pregnancy, the range alleged in exceptional medical reports, and a legal decision about a particular child. An accepted exceptional interval would show that the ordinary duration was not an inflexible rule; it would not establish a maximum for every subsequent case. For illustration, the later historical account in Legal medicine by Charles Meymott Tidy (volume 3) reports an English decision, dated there to 1834, allowing legitimacy after about 42 weeks, or 294 days, from last intercourse. This is a retrospective textbook report, not independent verification of the original judgment or proof of a longest accepted interval. The legal answer rests on the contemporary statement of the English rule, rather than on that numerical example.^[ref]

The medical evidence also requires care over the starting event. A period counted from the last menstruation is not the same measurement as a period counted from intercourse, and neither directly observes the instant of fertilization. Modern gestational age conventionally counts from the first day of the last menstrual period; early ultrasonography provides a more accurate check than menstrual recall alone. It would be misleading to combine historical figures with these different starting points into a single supposedly proved maximum.^[ref]

The absence of a predetermined English maximum did not make every length of separation legally acceptable or biologically possible. A claimed prolonged pregnancy still required credible evidence, and a nineteenth-century finding about legitimacy does not validate an extraordinary pregnancy length as a modern scientific observation. In historical legitimacy and prolonged gestation, the legal rule, the determination in an individual case, and the observed biological interval must be kept distinct. Establishing a unique longest reported case is a separate historical inquiry; it is not necessary to answer that English law prescribed no fixed maximum.
