Clinical Bacteriology and Hematology for Practitioners. By W. D'Este Emery, 

 M. D., B. Sc. Lond. Third edition. Cloth. Pp. xxxiv+252. Price $2 net. 

 Philadelphia: P. Blakiston's Son & Co., 1908. 



The author has endeavored to bring into the narrow confines of 350 

 pages those fundamental facts of bacteriology and hematology which are 

 needed by a physician who does not have access to a good laboratory. 

 The subject matter is presented in a remarkably clear manner and the 

 arrangement is such that for any particular examination a description of 

 the necessary apparatus and method of procedure is found in full, so that 

 the reader does not have to refer to various portions of the book to 

 obtain the desired information. This entails a certain amount of repeti- 

 tion, but greatly increases the practical value of the book. 



Since bacteriology has been taught in almost all. medical schools for 

 a number of years past, the younger generation of physicians will find 

 much here that would seem superfluous, along with many valuable 

 suggestions as to the clinical applications of his bacteriological knowledge. 

 The book is written, however, primarily for the older generation who 

 did not have any bacteriological training and for them it will prove to 

 be entirely satisfactory. 



Only very few errors have crept into the work. One misses bile media 

 in the blood culture of typhoid and V. Pirquet's cutaneous reaction for 

 tuberculosis. Owing to the entirely doubtful value of opsonic index 

 determinations, it would seem that too much space is given to their 

 discussion. 



The section on hsemotology is taken up mainly with the estimation of 

 the amount of haemoglobin, red and white cell counts, and the differential 

 leucocyte count. 



The accompanying plates are very satisfactory and add materially to 

 the usefulness of the book. 



The work as a whole is to be commended for its clearness and the 

 attention that has been given to details of practical value to the prac- 

 titioner.
