Undoubtedly the seasons at which the different experiments were made have an effect on our results apart from the simple absolute temperatures concerned. There is no doubt that the vaso-motor system of nerves plays an important part in the alterations of the peripheric temperature generally; and it would further appear that the steady elevation or depression of the atmospheric thermal mean accompanying the change of the seasons, acts more constantly and persistently on these nerves than transient and irregular variations of the temperature of the air. In a recent article on the peripheric temperature, M. Louis Couty has given evidence that the temperature of the palm of the hand is affected in a manner according with the above view.* Now the experiments of Table 1 were made in August and September; those of table 2 in March and April; and those of Table 3 and 4 in December, January, and February. Unfortunately the tables for the winter months do not range sufficiently high, and those for the spring and summer months do not range sufficiently low, to admit of a comparison of the effect of the same temperature of the air, at different seasons, on the temperature of the head. To make this comparison, the ranges of the atmospheric temperatures in the tables would have to be extended both upwards and downwards by artificial means.

"Such a book as that now under notice is indeed novel in its plan, and remarkably attractive and valuable in its achieved purpose......If one should begin to enumerate all the features that yield masterly effects to the eye or lend interest to the mind, the spirit of commendation would continue throughout the whole work. So much is there in this splendid series of plates that excites our admiration, that mere words of praise seem tame. One must pass an hour or more in turning over the leaves, and even then only a modicum of its value reveals itself. We are glad that the work has been brought before the profession of this country, since to practitioners as well as students it must prove of inestimable service. It fills a place not hitherto occupied, and meets a want that has often been expressed, but never satisfied. The publisher deserves thanks for his part of the enterprise, and we earnestly trust that a liberal patronage will reward him."-Boston Medical Library Journal.

"This valuable and classic series of illustrations, first published by Professor Edward Martin in 1861, has long had a great reputation in Germany as being of great service to practitioners as well as students of midwifery. It includes 98 pages of plates, with an average of 5 illustrations on each, many of which are coloured, and some drawn on a large scale, so as to occupy the whole page, where this has seemed desirable. The subjects treated range through the whole of midwifery and gynecology, beginning with normal and abnormal pelves, and ending with illustrations of some of the most important obstetric gynæcologic instruments used in Germany and in this country...... The descriptive letterpress is very full and accurate, and the whole makes an extremely handsome volume, of portly yet not of cumbrous size. This atlas has nothing of its kind to compete with it in the English language, and will no doubt be warmly welcomed by obstetricians and gynæcologists and students of the advanced class.”—British Medical Journal, July 10th, 1880.

"The atlas is the most complete and comprehensive work of its kind.......Nearly every point, anatomical, physiological, obstetrical, and gynæcological, is illustrated in the best way by well known authors, from whose works the late Dr. Martin culled his illustrations. As a work of reference to the practitioner, the atlas is invaluable; while to the student who wishes to refresh his memory in the readiest way, and in the shortest time, it will be very useful."-London Medical Record, July 15th, 1880.

BY

J. WICKHAM LEGG, F.R.C.P. Assistant Physician to Saint Bartholomew's Hospital, and Lecturer on Pathological Anatomy in the Medical School.

"It seems to us an exhaustive epitome of all that is known upon the subject."-Philadelphia Medical Times, 1880.

"It is, indeed, a valuable book, and the best storehouse of knowledge in its department that we know of."-Pacific Medical and Surgical Journal, San Francisco, 1880.

It is

"This volume is one which will command professional respect and attention. perhaps the most comprehensive treatise upon the subjects treated ever published in the English language...... The subjects discussed in this volume enter largely into the everyday work of the practising physician, and are among the most intricate and important in the whole domain of medical sciences. The liver being the largest gland in the human body, is of great importance in its functional relations to health. No organ is more abused or less understood.

In this treatise its functions are fully considered, and much light has been thrown upon its various relations to health and treatment in disease. The author has presented to the profession a work of great value."-Baltimore Medical Journal, U. S. A., 1880.

"The chapter which treats of the bile-acids on the heart is excellent, and the views of various experimenters are clearly and accurately given. The classification of xanthelasma is full and complete, and the coloured plates illustrating this condition of the skin will be found useful by practitioners...... The chapters which treat of acute yellow atrophy are, perhaps, the best in the book. We regret that want of space prevents our noticing some of the very valuable facts which are collected in these chapters, but we would advise every practitioner to read them. The immense number of bibliographical references in this book, will make it a valuable addition to the library of every educated practitioner."-The Birmingham Medical Review, Oct. 1880.

"The book is an exceedingly good one......is conspicuous for many very good points, and it is one of great merit......and we venture to say, after an attentive perusal of the whole, that anyone who takes it in hand will derive from it both information and pleasure; it gives such ample evidence of honest hard work, of wide reading, and an impartial attempt to state the case of jaundice, as it is known by observation up to the present date.. he has produced a distinct landmark in medical literature, from which most observers in the future will take their departure; and we venture to predict that his book will not only live, but be in the enjoyment of a vigorous existence long after some of the more popular productions of the present age are buried, past all hope of a resurrection."-London Medical Record, July, 1880.

"It is a valuable work of reference and a welcome addition to medical literature."— Dublin Journal of Medical Science, August, 1880.
