“I sat up one night reading this book as one reads a novel, which in the popular phrase, “cannot be put down.” I have rarely read so interesting a volume of any kind. It is scientific, accurate, clear, cogent, unanswerable, and satisfying to the last degree. I am delighted with it. The whole Christian world will thank you for it. I am going to use it unblushingly in a course of sermons later on.”—_Cyrus Townsend Brady._ “A volume which is not the less destructive for its moderation, and its fairness. Mr. Powell’s discussion of his subject is sane, temperate, and judicious, and his book merits the careful attention of all who are interested either from within or without in the all-important subject of Christian Science.”—_Springfield Republican._ “A fine piece of work.... I can but feel that in your book you have a little of the swing of Carlyle and the trust of Newman. I cannot, for the life of me, see what you have left for anyone else to say on the subject.”—_Rev. Nathaniel S. Thomas, Church of the Holy Apostles, Philadelphia._ _Send for descriptive circular_ G. P. PUTNAM’S SONS NEW YORK LONDON _“A unique little volume, one which deserves the thoughtful consideration of every practitioner.”—Sajou’s Monthly Cyclopedia and Medical Bulletin, Philadelphia._ Insomnia and Nerve Strain By Henry F. Upson, M.D. Professor of Diseases of the Nervous System in Western Reserve University, Attending Neurologist at the Lakeside Hospital, Cleveland, Ohio _Crown 8vo. With Skiagraphic Illustrations $1.50 net_ "An interesting theory in explanation of many cases of insomnia and insanity is brought forth and illustrated by Dr. Henry S. Upson of Cleveland, in his book on ‘Insomnia and Nerve Strain.’ Dr. Upson believes that very many cases of mania, melancholia, and dementia are caused by defective teeth. “The work is technical, and for the profession rather than the lay reader. It will doubtless prove of great value as a contribution to the warfare being waged against the mental scourges that fill our asylums with young people on the threshold of productive activity.”—_Cleveland Plain Dealer._ “Dr. Upson is, we believe, the first medical practitioner to write extensively on this topic and the first to accompany his writing with skiagraphs relating to his cases. His enthusiasm in this matter may be the means of arousing a greater interest in it than hitherto has been manifested by physicians.”—_New York Times._ “The author has presented his conceptions in a most attractive and entertaining manner and time alone will say whether his deductions will rest on true scientific ground. The treatment of insomnia if carried out along the lines suggested will not only benefit a great number of distressing conditions but will undoubtedly curtail the indiscriminate use of hypnotics at present prevailing.
