a accine it cannot do us any good. It may prove the means oi 
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 
careful inoculations, the attentive manner in which the post- 
moi terns have been made, the description of the new microbe to 
which the disease is attributed, all in fact, are minutely described 
m the Report; and the handsome plates that illustrate it assist 
considei ably in the study of the whole subject. The conclusions 
of the Report are very important, and give in a few words mate¬ 
rial for careful consideration. They say : 
“ Tlie preceding investigations definitely settle certain contro¬ 
verted points concerning the etiology of swine plague, which may 
be briefly summarized: 
1st. Sw ine plague is caused by a specific microbe multiplying 
in the body of the diseased animal. The microbe probably be¬ 
longs to the genus bacterium, and has the power of spontaneous 
movement. It is easily cultivated in nutritive liquids, but grows 
less readily on gelatine, which it does not liquefy. 
2d. When introduced beneath the skin, this bacterium is fatal 
to pigs, rabbits, guinea pigs, mice, and a certain percentage of pig¬ 
eons. It is also fatal to pigs when introduced with the food, or 
when they feed on the internal organs of swine which have 
died of the disease. 
3d. The disease described in 1 ranee as vouget , in Germany 
as rothlauf , and for which Pasteur has prepared a vaccine, is 
caused by an entirely different microbe. The vaccine for this dis¬ 
ease does not protect against swine plague. 
“4th. The introduction of Pasteur’s vaccine is not only use¬ 
less, but may contribute to the introduction and spread of a dis¬ 
ease, the existence of which in this country has not yet been 
demonstrated.”

it contains, gives a good account of the work done by the various
