THE ANATOMY OF VERTEBRATED 



ANIMALS. 



By THOMAS HENRY HUXLEY, LL. D., F. R. S. 

 l.vol., 12mo. Illustrated. 431 pages. Cloth, $2.50. 



" The present work is intended to provide students of comparative anatomy Avith a con- 

 densed statement of the most important facts relating to the structure of vertebrated animals 

 which have hitherto been a-scertained. The Vertebrata are distinguished from all other ani- 

 mals by the circumstance that a transverse and vertical section of the body exhibits two 

 cavities completely separated from one another by a partition. The dorsal cavity contains 

 the cerebro-spinai nervous system ; the ventral, the alunentary canal, the heart, and usually 

 a double chain of gan^^liaj which passes under the name of the ' sympathetic' It is prob- 

 able that this synipathetic nervous system represesents, wholly or partially, the principal 

 nervous system of the Aiiiutlosa and MoUusca. And, in any case, the central parts of the 

 cerebro-spinai nervous system, viz., the brain and the spinal cord, would appear to be un- 

 represented among invertebratod animals." — The Author. 



" This long-expected work will be cordially welcomed by all students and teachers of 

 Comparative Anatomy as a compendious, reliable, and, notwithstanding its small dimen- 

 sions, most comprehensive guide on the subject of which it treats. To praise or to criticise 

 the work of so accomplished a master of his favorite science would be equally out of place. 

 It is enouirh to say that it realizes, in a remarkable degree, the anticipations which have been 

 formed of it ; and that it presents an extraordinary combination of wide, general views, with 

 the clear, accurate, and succinct statement of a prodigious number of individual facts." —

THE ANATOMY OF INVERTEBRA- 



TED ANIMALS. 



By THOMAS HENRY HUXLEY, LL. D , F. R. S. 



1 vol., 12mo. Illustrated. 596 pages. Cloth, $2.50. 



"My object in writing the book has been to make it useful to those who wish to become 

 acquainted witli the broad outlines of what Ls at present known of the morphology of the 

 lurertebrata ; though I have not avoided the incidental mention of facts connected with 

 their physiology and their distribution. On the other handj I have abstained from discuss- 

 ing questions of etiology, not because I maderestimate their importance, or am insensible 

 to the interest of the great problem of evolution, but because, to my mind, the growing 

 tendency to mix up etioloj;ieal speculations with morphological generalizations will, if un- 

 checked", throw biology into confusion." — From Preface. 



THE COMPARATIVE ANATOMY OF 



THE DOMESTICATED ANIMALS. 



By A. CHAUVEAU, 



Professor at the Lyons Veterinary School. 



Second edition, revised and enlarged, with the co-operation of S. Arloisg, late 

 Principal of Anatomy at the Lyons Veterinary School ; Professor at the Toulouse 

 Veterinary School. Translated and edited by George Fleming, F. R. G. S., M. A. I., 

 Veterinary Surgeon, Royal Engineers. 



1 vol., 8vo, 957 pages. "With 450 Illustrations. Cloth, $6.00. 



" Taking it altogether, the book is a very welcome addition to English literature, and 

 great credit is due to Mr. Fleming for the excellence of the translation, and the many addi- 

 tional notes he has appended to Chauveau's treatise." — Lancet (London). 



"The descriptions of the text are illustrated and assisted by no less than 450 excellent 

 woodcuts. In a work which ranges over so vast a field of anatomical detail and description, 

 it is difficult to select any one portion for review, but our examination of it enables us to 

 speak in high terms of its general excellence. . . ." — Medical Times and Gazette {London).
