1889.] MICROSCOPICAL JOURNAL. 263 



The book is provided with thirty colored maps, nearly two hundred 

 sketch-maps, and woodcuts, drawn from the most authentic sources. 

 The illustrations are extremely valuable. 



Elements of Histology . By E. Klein, M. D. i2mo, 368 pp. 194 

 illustrations. Lea Brothers & Co., Phila. 



During the present year a new and enlarged edition of this standard 

 work has been issued, making it by far the best hand-book of histology 

 extant. The constant advance in our knowledge of this science has 

 permitted important additions to the volume. Some of these relate to 

 the division of the nucleus, the termination of nerves in the epithelium 

 and epidermis, as well as the absorption of chyle by the mucus mem- 

 brane of the small intestine. Rollett's views on the structure of striped 

 muscular tissues are adopted. Nearly all the organs of the body have 

 received attention, and their structure not only described but figured. 



The illustrations alone in this volume should awaken the highest en- 

 thusiasm in microscopical circles. Every one of the one hundred and 

 ninety-four figures is clear, distinct, properly described, and artistically 

 drawn. But especial mention must be made of the new photo-micro- 

 graphs taken by Mr. Andrew Pringle, and illustrative of the following 

 topics: Section of the adipose layer of the skin showing fat cells (X 

 40) ; intermediate cartilage of femur of a foetus ; section of medulla ob- 

 longata (X 150) ; section of tooth of a guinea-pig (X 150) ; early de- 

 velopment of a tooth ; the tongue of a cat with blood vessels injected ; 

 papilla foliata of a rabbit, showing taste buds (X 40) ; section through 

 taste organ ; section through trachea of a foetus ( X 40) ; net-work of 

 capillary blood-vessels surrounding the alveoli of lung. 



The type is new and clean, the paper of good quality, the binding in 

 a red cloth to correspond with the stained and polished edges. A good 

 index closes the volume. 



Annual of the Universal Medical Sciences. Edited by Charles E. 

 Sajous. F. A. Davis, publisher, Philadelphia, New York, and 

 London. Five vols. 8vo. 1889. $15. 



This is the second issue of the Annual, the first having been pub- 

 lished for the year 1888. It is essentially a report of yearly progress 

 in all matters relating to medicine or sanitation throughout the world. 

 The subject-matter is divided into nearly seventy departments, each 

 with its editors, corresponding editors, and collaborators. 



The work is a success. It evinces great energy and executive ability 

 on the part of its projectors, and, although much might have been 

 omitted, the details are fairly well worked out, and the live physician 

 can hardly afford to do without it, unless he already has a full list of 

 medical journals. 



Under the head of Etiology of Disease, bacteriological notes, of 

 course, occupy much space, the article by Ernst, of Boston, on this 

 subject, being clear, rational, and valuable. He attributes recent rapid 

 advancement of bacteriological knowledge to the general use of (1) 

 aniline dyes, (2) homogeneous immersion lenses and substage illumi- 

 nation, and (3) solid culture media. Methods are given for preparing 

 culture media, and for photographing test-tube cultures. He protests 

 against the rapid methods of staining the bacillus of tuberculosis, and
