No. 55 West Fourth Street, Cincinnati.   This is a new work, emanating from comparatively a new source; but should meet with no less favor on that account. The name has often too much influence upon the professional man when selecting his library, and, no doubt, causes the rejection of many valuable productions. We arc decidedly in favor of that author who thinks and acts for himself; provided, always, his thoughts and acts are orthodox, and his views based upon scientific research and practical experience. The author of this work has been engaged in teaching, has practical experience, and a sound judgment, which must give him a prominent position among his competitors for fame.   At first glance we were not favorably impressed with the introduction of Anatomy and Physiology in a work on the Practice of Medicine, but upon a more careful investigation this feature assumes importance, and our objections vanish. We give, in the authors own words, his reasons for this course:   "It will be seen that I have glanced at the anatomy and physiology as I have taken up the diseases peculiar to each part of the human system. This I have done in part to make the work more valuable to those practitioners of medicine who have not time to review anatomy and physiology; but more especially to keep the mind of the reader fixed on the diseased part, and its conditions, thus rendering the work not only more valuable, but, I trust, more interesting."
