of his labors. His reports embrace important investigations of 
contagions pleuro-pnenmonia, swine plague, southern cattle fever, 
gapes in fowls, verminous bronchitis, and meat cattle quarantine. 
The latter half of the work contains the reports of agents and in¬ 
spectors of the Bureau, upon some interesting agricultural subjects. 
The last 100 pages give a synopsis of the enormous amount of work 
performed by the veterinarians of the Bureau, in their inspections 
respecting the existence of pleuro-pnenmonia in Hew York, Hew 
Jersey, Delaware, the District of Columbia, Maryland, Yirginia 
and Kentucky. A careful examination of this portion of the 
book proves that the gentlemen engaged in the inspection 
have done well, and that their positions have been far from being 
sinecures. 
To veterinarians, however, we believe the first part of the 
report will prove most interesting, and an attentive reading 
of the various articles cannot fail to gratify the reader. But 
amongst them all, probably none will deserve more atten¬ 
tion than that which relates to swine plague, a better name, 
no doubt, than that of hog cholera—if, as Dr. Salmon almost 
proves,^the disease which prevails here is not, after all, that which 
many have been accustomed to consider the same as the disease of 
Europe, known by the same name. Much had been done by the 
chief veterinarian of the bureau; for years he has worked in the 
investigation of the scourges of swine, and no one in this country 
lias had better opportunities for studying not only the symptoms 
of the lesions, but everything connected with that disease. And 
though some of the ideas he advanced some years ago may be 
surrendered to make room for others of a different nature, there is 
no doubt in our mind that all that Dr. Salmon has said and 
written in the second Report is done with conviction and with 
evidences to back him. He has stated that the swine plague of 
the United States is not the same as that of Europe, and when he 
has been convinced he has said; * c Do not believe in Pasteur’s 
vaccine—it cannot do us any good. It may prove the means of 
introducing a new disease which will bring untold loss to the swine 
breeders of this country.” 
The manner in which he has conducted his investigation, the
