eases of the nervous system, as tetany, Thomsen's 

 disease, miryachit, and kindred affections. In all 

 respects we must place this treatise as the best in the 

 language on the specialty to which it is devoted." 

 Medical and Surgical Reporter. 



"When a work has reached its eighth edition, 

 the reviewer might as well keep quiet, as the book- 

 buyer has already decided that a demand has been 

 met." New York Medical Times. 



"This volume has been received by the profes- 

 sion ' to an extent beyond that ever given to any 

 other work of like scope and objects published in any 

 part of the world.' The present edition contains a 

 section on ' Certain Obscure Diseases of the Nervous 

 System,' is thoroughly revised throughout, and sev- 

 eral changes made, thereby increasing greatly its use- 

 fulness." Buffalo Medical and Surgical Journal. 



' ' The eighth edition of this work speaks for itself 

 in the fact of its existence. The talented author 

 has carefully revised the previous editions, elaborat- 

 ing many portions which subsequent experience and 

 observation have made necessary. A section has 

 also been added on certain obscure diseases of the 

 nervous system, comprising tetany, Thomsen's dis- 

 ease, miryachit, and kindred affections. These sub- 

 jects are treated, like others in the work, with a 

 master-hand and with the pen of a ready and enter- 

 taining writer. The author made his reputation long 

 ago, and that he is able to maintain it his last effort 

 will abundantly prove." Medical Record.

CLINICAL LECTURES ON DISEASES OF THE 



NERVOUS SYSTEM. Delivered at the Bellevue hospital Medical Col- 

 lege. By WILLIAM A. HAMMOND, M. D., Professor of Diseases of the Mind 

 and Nervous System, etc. Edited, with Notes, by T. M. B. CROSS, M. D., 

 Assistant to the Chairs of Diseases of the Mind and Nervous System, etc. 

 In one handsome volume of 300 pages. $3-$o. 



These lectures have been reported in full, and, together with the histories of the cases, which 

 were prepared by the editor after careful study and prolonged observation, constitute a clinical 

 volume which, while it does not claim to be exhaustive, will nevertheless be found to contain 

 many of the more important affections of the kind that are commonly met with in practice. 



As these lectures were intended especially for the benefit of students, the author has confined 

 himself to a full consideration of the symptoms, causes, and treatment of each affection, without 

 attempting to enter into the pathology or morbid anatomy. 



THE ANATOMY OF VERTEBRATED ANIMALS. 



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



I vol., I2mo. Illustrated. 431 pp. Cloth, $2.50. 



" The present work is intended to provide students of comparative anatomy with a condensed 

 statement of the most important facts relating to the structure of vertebrated animals which have 

 hitherto been ascertained. The Vertebrata are distinguished from all other animals by the circum- 

 stance 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-spinal nervous system ; 

 the ventral, the alimentary canal, the heart, and usually a double chain of ganglia, which passes 

 under the name of the ' sympathetic. ' It is probable that this sympathetic nervous system repre- 

 sents, wholly or partially, the principal nervous system of the Annulosa and Mollusca. And, in 

 any case, the central parts of the cerebro-spinal nervous system, viz., the brain and the spinal 

 cord, would appear to be unrepresented among invertebrated animals." The Author. 



' ' This long-expected work will be cordially wel- 

 comed by all students and teachers of Comparative 

 Anatomy as a compendious, reliable, and, notwith- 

 standing its small dimensions, 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 enough to say that it realizes, in a remarkable 

 degree, the anticipations which have been formed 

 of it ; and that it presents an extraordinary combi- 

 nation of wide, general views, with the clear, accu- 

 rate, and succinct statement of a prodigious number 

 of individual facts." Nature.
