The immediate success of this work is due to the special features that distinguish it from other books of its kind. It gives a maximum of matter in a minimum space and at the lowest possible cost. Though it is practically unabridged, yet by the use of thin bible paper and flexible morocco binding it is only 1¾ inches thick. The result is a truly luxurious specimen of book-making. In this new edition the book has been thoroughly revised, and upward of two thousand new terms that have appeared in recent medical literature have been added, thus bringing the book absolutely up to date. The book contains hundreds of terms not to be found in any other dictionary, over 100 original tables, and many handsome illustrations, a number in colors. PERSONAL OPINIONS =Howard A. Kelly, M. D.=, _Professor of Gynecology, Johns Hopkins University, Baltimore_. “Dr. Dorland’s dictionary is admirable. It is so well gotten up and of such convenient size.

(Hon.)=, _Professor of Surgery, Harvard Medical School_. “I regard it as a valuable aid to my medical literary work. It is very complete and of convenient size to handle comfortably. I use it in preference to any other.” Heisler’s Text-Book _of_ Embryology Recently Issued--The New (3d) Edition =A Text-Book of Embryology.= By JOHN C. HEISLER, M.D., Professor of Anatomy in the Medico-Chirurgical College, Philadelphia. Octavo volume of 435 pages, with 212 illustrations, 32 of them in colors. Cloth, $3.00 net. WITH 212 ILLUSTRATIONS, 32 IN COLORS The fact of embryology having acquired in recent years such great interest in connection with the teaching and with the proper comprehension of human anatomy, it is of first importance to the student of medicine that a concise and yet sufficiently full text-book upon the subject be available. This new edition represents all the latest advances recently made in the science of embryology. Many portions have been entirely rewritten, and a great deal of new and important matter added. A number of new illustrations have also been introduced and these will prove very valuable. The previous editions of this work filled a gap most admirably, and this new edition will undoubtedly maintain the reputation already won. Heisler’s Embryology has become a standard work. PERSONAL AND PRESS OPINIONS =G. Carl Huber, M. D.=, _Professor of Histology and Embryology, University of Michigan, Ann Arbor_. “I find the second edition of ‘A Text-Book of Embryology’ by Dr. Heisler an improvement on the first. The figures added increase greatly the value of the work. I am again recommending it to our students.”
