77 journal is published in Amsterdam, Madrid Brussels, London, St. PetersParis, Rome, Leipzig, It is printed in and Stockholm. Vienna, Lisbon, burg, double columns, chiefly in French, but sometimes in French and German, and in one instance in French and English. Many well-known names appear as collaborateurs, and some of the articles in the first number are interesting and valuable. Of the articles, some are devoted to descriptions of the measures adopted in different countries for the repression of adulteration, while others deal with methods of analysis. In the latter class must be mentioned the valuable paper of Professor Konig of Miinster on Peptones, and of Professor Hanauset of Vienna on the Adulteration of Spices. The latter is illustrated with microscopic drawings, and the author, who has much to tell, promises a further communication. Defects due to the polyglot character of the journal are evident enough, but these will doubtless diminish as the work goes on. We sincerely wish the Amsterdam editor success in his difficult undertaking. Transactions of the Medical and Physical Society of Bombay. No. X. New Series.—It is very encouraging to find that medical science is not neglected even abroad, and by those whose time must leave but little leisure for recording clinical and other observations. For this reason we welcome these Transactions and we esteem those of our conf reres who have found time to record some of their cases. The short notes on enteric fever by Surgeon Richard Baker, Brigade Surgeon C. MacDowall, and Surgeon M. A. T. Collie contain much that is practical and instructive. Brigade Surgeon H. V. Carter has contributed the following interesting cases, and his discussion of them shows the possession of considerable clinical acumen: -1. Clinical Memorandum on a Case of Complete Plugging of the Right Pulmonary Artery, associated with Mitral Stenosis and Incompetency and with Pulmonary Apoplexy; atheroma of both pulmonary arteries. 2. Notes of a Case of Fever (? Enteric) ending fatally from Ulceration and Perforation of the Ileum; compiled from data furnished by Surgeon P. J. Damania, in charge of Satara. Gaol, with specimen and drawing, forwarded through the President of the Society. Some remarks on Fodor’s Experiments concerning the Microbe-killing Power of the Healthy Blood Current, with some application to Indian disease, by Brigade Surgeon C. MacDowall; Notes on a Case of Ainhum, by Assistant Surgeon K. B. Cooper, and a note on Lobelia Nicotianaefolia, by Surgeon-Major W. Dymock, are other interesting communications. Dr. W. Gray, Dr. Kirtikar, Veterinary Surgeon J. H. Steel, Surgeon A. Faulkner, and Dr. Ghollay have also contributed to this volume. The A B C of Modern (Dry Plate) Photography. Twentysecond Edition. London: The London Stereoscopic and Photographic Company (Limited).-The first forty pages of this little book are devoted to the most elementary instruction, and are clear, practical, and not overburdened with detail. Then follow chapters for the more advanced student, including lantern slides, enlarging, paper negatives, various modes of printing (old and new), and photomicography. It is difficult to overrate the value of the camera, correctly used, as a means of registering scientific facts, and with progress in electric and other brilliant artificial lighting its use will probably be greatly extended in clinical application. No amount of book-reading will enable an indifferent photographer to advance beyond a certain point, but a volume like the present will open the gate to many to whom the easily mastered art will be of the greatest value. adulteration.

New Inventions. LAMP FOR LARYNGOSCOPIC AND OPHTHALMOSCOPIC EXAMINATION. THE accompanying illustration represents a new form of lamp for laryngoscopic and ophthalmoscopic examination, and, combining as it does the advantage of convertibility into an ordinary reading lamp, will, I think, be found exceedingly useful by members of the medical profession, especially where gas is not obtainable. The light can be arranged at any height or turned in-any direction, and fixed at that point by means of the binding screw on the upright rod. The lamp is fitted with a Silber burner, and when arranged for laryngeal and rhinoscopic examinations, as shown in the woodcut,. the condensed light is equivalent to twenty-five standard candles. For ophthalmoscopic purposes the cover is closed over the bull’s eye, the

chimney rotated, and light of ten-candle power "is obtained by a

opening the shutter. One feature of the lamp is using a chimney of large diameter with perforated collar at the base to allow the passage of a stream of cool air between the glass and metal chimneys, thereby preventing fusion of the former. The chimney itself is of blue glass, to provide for the absorption of the yellow rays. For use as an ordinary lamp it is merely necessary to remove the metal chimney and adapt the opaque glass shade. I have had the lamp in constant use for a period of eighteen months, and it is as efficient now as when it left Messrs. Down Bros., of St. Thomas’s-street, who are the makers. GEO.

MIDWIFERY FORCEPS. MESSRS. ARNOLD AND SON have made for me midwifery forceps, embracing the following points of construction : Long curved blades with handles correspondingly curved, so as to secure parallel axis traction, and knot at end of handle to prevent slip; also with joint allowing enough

lateral lock play to admit of automatic adjustment to cranium. I have found this uncomplicated instrument unequalled for facility and safety of application on back or reach, grasp, and economy of force.
