PREFACE TO THE SECOND EDITION.

In preparing this edition, I have done my utmost to correct
inaccuracies and remove obscurities. The changes rendered
necessary by recent research have also been made.

Some parts have been rewritten; notably the chapters on the
Central Nervous System, to which additional illustrations have

been added.

The general arrangement remains the same as that of the

First Edition.

I am again deeply indebted to my friend, Mr. E. F. Herroun, for much valuable assistance.
