BIBLIOGRAPHY. 
French. It is a fairly complete resume of our knowledge on the 
subject, with especial attention to the pathogenic varieties that 
now occupy so large and increasing a share of medical attention. 
In most works on bacteriology, the microbiology of animal dis¬ 
eases is relegated to a subordinate position, the maladies which 
affect human beings being necessarily of primary importance. 
The reverse is here the case, and those concerned in the treat¬ 
ment of animal diseases, the book fills an entirely unoccupied 
place. 0 
The first portion is devoted to general considerations of the 
morphology and physiology of microbes. The second portion 
treats of the pathogenic microbes, their transformation and de¬ 
struction, and their relation to hygiene and therapeutics. The 
third and last portion considers the microbic diseases individu¬ 
ally, and the latest methods of combating them. 
The book is not intended to be a laboratory manual, and 
consequently the technique of staining and cultivation of germs 
is not exhaustively treated. An increase in the number of illus¬ 
trations would have been an advantage ; more especially as the 
veterinarian rarely gets the opportunity to familiarize himself 
practically with these organisms. We can heartily recommend 
the work to our readers.—W. GoTTHEIL. 
Investigations Concerning Bovine Tuberculosis , with special 
reference to diagnosis and prevention. Conducted under the 
direction of Dr. E. Salmon,. Bureau of Animal Industry. 
Bulletin No. 7. 
This is a large pamphlet of some 180 pages with illustra¬ 
tions containing the report of the investigations made by Drs. 
Theobald Smith, F. L. Kilborne and E. C. Schroeder concern¬ 
ing the diagnosis and prevention of tuberculosis, to which is 
added the results of tests made in the use of tuberculin by Dr. 
E. A. de Schweinitz. 
At this time when tuberculosis occupies so much of the pub- • 
lie and scientific attention, these reports will prove very inter¬ 
esting and of great value, especially when they are the results of
