Transcriber’s Notes
Page 127, cutting window in: either in the wrong place alphabetically,
or it is an error for window, cutting in.
The (unusual) spellings zonuloe and zonulœ have been retained.
Changes:
Footnotes have been moved to the end of the chapter in which they are
referenced. Illustrations have been moved out of text paragraphs.
Some obvious minor typographical and punctuation errors have been
corrected silently.
In some illustrations the reference letters have been accentuated.
Page 11, 12: Illustration numbers added.
Page 127, Gland, racemose construction: page number 114 added.
Page 130: the entries iris and lens have been moved to their proper
place; the entry Retinæ, pars ciliaris has been moved to a separate
line.
