August 1866 republication of Benjamin Ward Richardson's account. The introductory editorial note says an extract had appeared in the May issue. Apparatus details were inspected in indexed original text; its historical account of sensation is not adopted as current neuroscience.
Regulatory label, especially sections 4 and 5. Cited for established pharmacological hazards and contraindications, with present clinical context supplied by MedlinePlus and NICE; not a historical 1866 recipe.
Royal Medical and Chirurgical Society report abstract, Edinburgh Medical Journal 10, pp. 185–192. Physiological effects, administration and surgical contraindications. Contemporary report of the committee position: Medical Circular, 13 July 1864, p. 27, upload.wikimedia.org/wikipedia/commons/f/f6/Medical_Circular_%28IA_medicalcircular23londuoft%29.pdf . Its safety judgements are historical, not current anaesthesia guidance.
William Withering; title page and dated Preface establish the edition. Preface and Effects, Rules, and Cautions give the clinical method and toxicity observations. Historical evidence, not a current dosing guide.
Health Effects of Mercury Exposure, Elemental Mercury: little absorption on swallowing liquid metal compared with ready absorption of vapour. The contrast is relevant to interpreting historical treatment and does not validate it.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
