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.
