I try to edit my e-texts so they can easily be used with voice speech programs, I believe blind people and children should also be able to enjoy the many books now available electronically. I use the -- for an em-dash, with a space either before or after it depending on its usage. This helps to keep certain programs from squishing the words together, such as down-stairs. Also to help voice speech programs I've enclosed upper case text between - and _ (-UPPER CASE TEXT_), and used underscores to show chapter and section headers. I also added a second contents that shows the other sections of this e-text. This e-text was made with a "Top can" text scanner, with a bit of correcting here and there.

This book is volume one of two. It was later reworked by A. M. Davies in 1898 under the title "Text-book of Zoology", then revised and rewritten by J. T. Cunningham about 1909 and W. H. Leigh-Sharpe around 1932. Although these editions gave Wells the main credit, most of Wells' writing and all his drawings were removed; only his rough outline seems to have been used. It was re-published by University Tutorial Press.

The First Edition, as well as The Second and Revised Edition (with dissections redrawn by Miss A. C. Robbins) are used in this e-text. The First Edition had some small minor errors, as well as dissection abbreviations that are shown on the Dissection Sheets, but no mention of them was listed in the text. Certain figures on the Dissections Sheets are missing (such as Figures 1, 2, 4, with no mention to a 3, as if Mr. Wells drew a Figure 3 but found it was not needed and removed it from the book). Rather then leaving it as is, I put {} marks around my notes saying things like {No Figure 3}. For the "Second and Revised Edition" Wells was able to change some of these errors and missing parts, but many of the same printing tablets were used and with almost each addition other things were removed, (in one instance one entire section from a chapter), and many of the helpful suggestions were shortened or removed so other things could be explained more. In an ideal version of the book both could have been used, but with reprinting the entire book from the first to the second editions almost as many things were lost as were gained, so I've tried to indicate where both text go separate paths with the following; [Second Edition only text] and -First Edition only text,- and also {Lines from Second Edition only.} and {Lines from First Edition only.} were more then just a sentence is added or removed. Other things to notice is how some words are spelt or punctuated differently throughout the book, such as; Blood Vessels Blood-Vessels Bloodvessels I've tried to keep these as close to the original book as possible.

H. G. Wells wrote this textbook in 1893, years before The War of the Worlds made him a household name. The prose is not that of a novelist but of a practical instructor: direct, economical, and focused on observable structure. Wells guides the student through dissections of frog, rabbit, and dogfish, comparing skeletal and organ systems with an emphasis on evolutionary relationships. The dogfish, he notes, represents a “far more antique type of structure” than previously considered forms, and he draws attention to features that link it to higher vertebrates. The text is stripped of ornament; its authority comes from precise anatomical terminology and step-by-step instructions for laboratory work.

Comparative Anatomy as a Method

Wells builds the book around direct comparison. In the frog and rabbit, he asks the student to “compare the skull … especially in regard to the attachment of the jaw apparatus to the cranium, and other points which distinctly characterize the higher as contrasted with the lower vertebrata.” The instruction is not merely descriptive but analytical: the student must “point out exactly what parts correspond with one another.” This comparative framework extends to the dogfish, where Wells contrasts its cartilaginous skeleton with the bony skeletons of more derived fish like cod or salmon. The method is consistent: each dissection is a lesson in homology, not just anatomy.

The Dogfish as a Living Fossil

Wells presents the dogfish as a window into deep time. He writes that forms “closely related to it occur among the earliest remains of vertebrata” and that since the Silurian period, sharks “have probably remained without any essential changes of condition, and consequently without any essential changes of structure.” This evolutionary perspective is woven into the description: the dogfish lacks a swim bladder, has placoid scales that are structurally homologous to teeth, and retains a cloaca. Wells uses these features to argue that the dogfish preserves “features which may have been disguised or lost” in more specialized fish. The language is measured but the implication is clear: the dogfish is a key to understanding vertebrate ancestry.

Diction of Dissection

Wells’s vocabulary is technical but not opaque. He uses terms like “fronto-parietal,” “parasphenoid,” “sphenethmoid,” and “pro-otic” without glossing them, assuming a student already familiar with basic osteology. Yet his sentences are short and imperative: “Prepare the skull of the frog provided. Remove from it and place in glycerine on a glass slip the fronto-parietal and parasphenoid bones. Label them.” The rhythm is that of a laboratory manual, not a lecture. When describing the dogfish skin, he explains that each placoid scale “consists of a base of true bone, with a little tubercle of a harder substance, dentine, capped by a still denser covering, the enamel.” The hierarchy of tissues is presented as a series of layers, mirroring the embryonic origin he then cites.

Voice and the Student

Wells rarely uses the first person. The text is almost entirely in the second-person imperative or the third-person descriptive. The student is addressed directly: “Compare the skull of the rabbit and the frog”; “Describe the skeleton of the upper and lower jaw.” There is no praise or encouragement, only a sequence of tasks. The effect is to place the student in the role of an investigator, not a passive reader. When Wells does offer interpretation—as in the dogfish’s evolutionary stasis—he does so in a declarative, almost impersonal tone: “They probably branched off from the other vertebrata before bone had become abundant.” The authority is that of a working biologist, not a popularizer.

Readers approaching this text should expect a rigorous, hands-on guide to vertebrate anatomy, not a general introduction. Wells assumes a laboratory setting with preserved specimens, scalpels, and glycerine slides. The book rewards careful attention to the comparative method: each dissection is designed to reveal evolutionary relationships through structural correspondence. For those interested in Wells’s intellectual development, the textbook shows a mind trained in observation and classification—skills he would later apply to social and scientific speculation.

I remember how Text Book of Biology taught me that patient dissection reveals quiet order beneath seeming chaos. Years later, seeing words arranged for hesitant foreign readers, I felt the same gentle trust in another’s ability to piece things together.
