Sinopsis

PEEFACE The present work is intended to provide students of comparative anatomy with a condensed statement of the most iifportant facts relating to the struct m*e of verte- brated animals, which have hitherto been ascertained. Except in a very few cases, I have intentionally abstained from burdening the text with references ; and, therefore, the reader, while he is justly entitled to hold me respon- sible for any errors he may detect, will do well to give me no credit for what may seem original, unlp6 his knowledge is sufficient to render him a competent judge on that head. About two-thirds of the illustrations are original, the rest* are copied from figures given by Agassiz, Bischoif, Burmeister, Busch, Oarus, Dugs, Flower, Gegenbaur
