 geon to the West London Hospital, and Ophthalmic Surgeon 

 to St. Mary's Hospital, London. With 20 Illustrations. i2ino. 

 Cloth, $1.25. 



" Dr. Hart is not an enemy of the spiritual, but he gives ground to neither the 

 supernatural nor the preternatural when he can help it. His state of mind is generally 

 impartial." — Chicago Post 



'* Mr. Hart holds it as proved beyond all reasonable doubt that the hypnotic con- 

 dition is an admitted clinical fact, and declares that the practice of hypnotism, except 

 by skilled physicians, should be forbidden. He affirms its therapeutic usetessness, and 

 condemns the practice because of the possibilities of social mischiefs. . . , His per- 

 sonal experiences in the ' New Witchcraft ' enable him to exercise a critical check on 

 the wild theories and unsupported assertions of others." — Philadelphia Ledger. 



n^ESMERISM, SPIRITUALISM, ETC., HIS- 

 iVl TORICALLY AMD SCIENTIFICALLY CONSID- 

 ERED. By William B. Carpenter, M. D., F. R. S. i2mo. 

 Cloth, $1.25. 



" The reader of these lectures will see that my whole aim is to discover, 

 on the generally accepted principles of testimony, what are facts ; and to 

 discriminate between facts and the inferences drawn from them. I have no 

 other ' theory ' to support than that of the constancy of the well-ascertained 

 laws of Nature." — From the Preface. 



miNCIPLES OF MENTAL PHYSIOLOGY. 



With their Application to the Training and Discipline of the 

 Mind, and the Study of its Morbid Conditions. By William 

 B. Carpenter, M.D., F. R.S. i2mo. Cloth, $3.00. 



" Among the numerous eminent writers this country has produced none are more 

 deserving of praise for having attempted to apply the results of physiological research 

 to the explanation of the mutual relations of the mind and body than Dr. Carpenter." 

 — London Lancet. 



AJATURE AND MAN: Essays, Scientific and 



-^ * Philosophical. By William B. Carpenter, M. D., F. R. S. 



With an Introductory Memoir by J. EsTLiN Carpenter, M. A., 



and a Portrait. i2mo. Cloth, $2.25. 



" B"ew works could be mentioned that give a better general view of the change that 

 has been wrought in men's conceptions of life and Nature. For this, if for nothing 

 else, the collection would be valuable. But it will be welcomed also as a kind of 

 biography of its author, for the essays and the memoir support one another and are 

 mutually illuminative." — Scotsman. 



"Mr. Estlin Carpenter's memoir of his father is just what such a memoir should be 

 —a simple record of a life uneventful in itself, whose interest for us lies mainlv in the 

 nature of the intellectual task so early undertaken, so strenuously carried' on, so 

 simple and nobly accomplished, to which it was iityotsA."— London spectator.
