A TREATISE ON INSANITY, in its Medical Relations. 

 By WILLIAM A. HAMMOND, M. D., Surgeon-General U. S. Army (retired 

 list) ; Professor of Diseases of the Mind and Nervous System, in the New 

 .York Post-Graduate Medical School ; President of the American Neuro- 



logical Association, etc.

Cloth, $5 ; sheep, $6. 



In this work the author has not only considered the subject of Insanity, but has prefixed that 

 division of his work with a general view of the mind and the several categories of menial faculties, 

 and a full account of the various causes that exercise an influence over mental derangement, such 

 as habit, age, sex, hereditary tendency, constitution, temperament, instinct, sleep, dreams, and 

 many other factors. 



Insanity, it is believed, is in this volume brought before the reader in an original manner, and 

 with a degree of thoroughness which can not but lead to important results in the study of psycho- 

 logical medicine. Those forms which have only been incidentally alluded to or entirely disregard- 

 ed in the text-books hitherto published are here shown to be of tlie greatest interest to the general 

 practitioner and student of mental science, both from a normal and abnormal stand-point. To a 

 great extent the work relates to those species of mental derangement which are not seen within 

 asylum walls, and which, therefore, are of special importance to the non-asylum physician. 

 Moreover, it points out the symptoms of Insanity in its first stages, during which there is most 

 hope of successful medical treatment, and before the idea of an asylum has occurred to the patient's 

 friends. 



" We believe we may fairly say that the volume 

 is a sound and practical treatise on the subject with 

 which it deals ; contains a great deal of information 

 carefully selected and put together in a pleasant and 

 readable form ; and, emanating, as it does, from an 

 author whose previous works have met with a most 

 favorable reception, will, we have little doubt, obtain 

 a wide circulation." The Dublin Journal of Medi- 

 cal Science. 



"... The times are ripe for a new work on in- 

 sanity, and Dr. Hammond's great work will serve 

 hereafter to mark an era in the history of American 

 psychiatry. It should be in the hands of every 

 physician who wishes to have an understanding of 

 the present status of this advancing science. Who 

 begins to read it will need no -urging to continue ; 

 he will bs carried along irresistibly. We unhesitat- 

 ingly pronounce it one of the best works on insan- 

 ity which has yet appeared in the English language." 

 American Journal of the Medical Sciences. 



" Dr. Hammond is a bold and strong writer, has 

 given much study to his subject, and expresses him- 

 self so as to be understood by the reader, even if the 

 latter does not coincide with him. We like the book 

 very much, and consider it a valuable addition to the 

 literature of insanity. We have no hesitancy in 



commending the book to the medical profession, as 

 it is to them it is specially addressed." Therapeutic 

 Gazette. 



" Dr. Hammond has added another great work 

 to the long list of valuable publications which have 

 placed him among the foremost neurologists and 

 alienists of America ; and we predict for this volume 

 the happy fortune of its predecessors a rapid jour- 

 ney through paying editions. We are sorry that our 

 limits will not permit of an analysis of this work, 

 the best text-book on insanity that has yet appeared." 

 The Poly clinic. 



' ' We are ready to welcome the present volume 

 as the most lucid, comprehensive, and practical ex- 

 position on insanity that has been issued in this 

 country by an American alienist, and furthermore, 

 it is the most instructive and assimilable that can be 

 placed at present in the hands of the student unini- 

 tiated in psychiatry. The instruction contained 

 within its pages is a food thoroughly prepared for 

 mental digestion : rich in the condiments that stimu- 

 late the appetite for learning, and substantial in the 

 more solid elements that enlarge and strengthen the 

 intellect," New Orleans Medical and Surgical 

 Journal.
