The Essentials of Virus Diseases

THIS new edition contains six hiundred and thirty-seven plates, many of which hiave two or more separate figures, of half-tone and line drawings. Over seventy of the illustrations are new, and colour has been used with good effect to bring out salient features. The original procedures of photographing the prepared specimens, and making outline drawings from the photographs for use by the artist in the preparation of the finished illustrations, have again been used. This method ensures that a considerable degree of accuracy of detail is attained, a very important matter in a work of this kind. The bronchial tree and broncho-pulmonary segments are well illustrated, but the Basle Nomino Anatomica (B.N.A.) has been used instead of aomenclature approved by the Thoracic Society. Also, corrosion specimens shoving variation in the pancreatic ducts, the arterial supply of the head of the femur, knee and nose, and the dermatomes according to Keegan, are among the subjects newvly illustrated. The old scheme of the zutaneous nerve distribution after Foerster has been retained, and useful comparison between .he clinical and experimental finldings can be made. The production of the plates and of the book as a wvhole is exceedingly good, and the general presentation of the regional anatomy so clear that rapid revision is greatly facilitated. This is a book which can be highly recommenided to both studenit and graduate alike. W. R. M. M.
