The explanations retain the historical meanings of the names while using modern chemical formulas and atomic weights. Historical analytical methods are distinguished from present water quality assessment.

The answers distinguish explanations available in December 1867 from later discoveries. In particular, the historical expressions pneumogastric nerve, eremacausis and Entozoa require interpretation rather than unqualified adoption.

These solutions reconstruct therapeutic reasoning available in December 1866 and distinguish it from present medical conclusions. They are not an official answer key. Clinical patterns are explanatory examples, not observations of an actual patient. Historical drugs and procedures are discussed as historical practices, not current prescriptions.

Historical terms in these solutions are interpreted in their 1866 setting. Present-day mechanisms and tests are identified separately.

These historical educational solutions distinguish reasoning available in December 1866 from present scientific conclusions. They are not an official answer key. Clinical examples describe possible patterns, not an actual patient's observations. Historical procedures and drugs are identified as period practices, not current prescriptions.

Historical terms are interpreted in their nineteenth-century setting. Modern explanations and measurements are identified where they extend beyond the knowledge available in December 1866.

The explanations distinguish the descriptive categories used in 1865 from present pathology. They are educational accounts of disease mechanisms and examination findings.

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.
