turned through 180 degrees does not affect this relation. If necessary, the posi- 

 tion of the paraffin block on the bar may be changed. The cube may be brought 

 back to its original position in the microtome by means of the line drawn at the 

 edge of the clamp, and the sections cut. Different parts of the object may be 

 cut in different planes without waste of material since its position is definitely 

 known. E. M. Brace.

sity of Buffalo. Pp. X., 263, 78 illustra- ^^logy, nor to take the place of the 

 tions. P. Blakiston's Sons & Co., Phila., larger text-books, but rather to present 



in concise and intelligible form the 

 more important facts of the science and its special technique, for the 

 benefit of beginners and of physicians who have not had an opportunity to obtain 

 much laboratory training in this subject. 



The book is divided into four parts, dealing respectively with bacteriological 

 technique, the classification and biological characteristics of bacteria (including 

 a discussion of toxines, immunity, etc.), non-pathogenic, and pathogenic bac- 

 teria. A chapter on disinfectants and antiseptics is contributed by Dr. Thomas 

 B. Carpenter, and one on preparation of instruments, ligatures, dressings, etc., 

 for surgical purposes, by Dr. Chauncey P. Smith. 



The topics discussed in the book are viewed from the medical standpoint 

 distinctively, and the facts which most concern the physician are discussed in 

 such a plain and thoroughly practical manner as to be readily understood even 

 by one who is not at all familiar with the subject from its laboratory side. 



It is to be hoped that the manual may have a large circulation, even if for 

 no other reason than to correct the pronunciation prevalent among medical 

 men of the generic terms ending in " cocci," as micrococci, staphylococci, and 

 streptococci. The physician who fails to pronounce these words as though 

 they ended in " cock-eye " is very seldom met. For the proper pronun- 

 ciation see Dr. Williams' manual, page 11, or any dictionary.
