INOCULATION FOIt THE LUNG PLAGUE, ETC.

inoculated .—This lias been proved by the disease breaking out 
among cattle where it had not previously shown itself, after their 
coming in contact with some inoculated animals which were free 
from the disease when inoculated. Oases of this sort, and even 
of cattle being inoculated before the disease had broken out 
among them, are so few that decisive evidence in this way is far 
from plentiful, but it is sufficent to establish the general fact. 
Further, it has frequently been the case, where all the others were 
inoculated, that a few head have been missed, and the percentage 
of deaths among those which were not operated on was always 
excessive ; thereby showing that the inoculation of the disease on 
every side of them not only rendered their escape from the con¬ 
tagion impossible, but seemed to increase the viruleney of the dis¬ 
ease.” 
The writer can fully endorse this statement from his experi¬ 
ence in New York. In certain stables it was the practice to in¬ 
oculate every animal as soon as received. In some such stables 
no disease of the lungs would appear so long as the system was 
fully carried out; but sometimes a bull or a calf would be left 
without inoculation, and such almost invariably fell a victim to the 
malady. 
In New Jersey, prior to the enforcement of the State meas¬ 
ures for the suppression of the disease, inoculation was loudly 
praised, and was frequently adopted even in herds that had shown 
no disease. The State veterinary inspectors reported various 
cases in which, after the inoculation of a healthy herd, the disease 
of the lungs had appeared in the herd in question. 
Reynal (a strong advocate of inoculation), in his Police sani- 
taire des Animaux domestiques,” p. 458, says, apropos of the 
question of the specific, virulent character of the inflammation in 
the inoculation wound : 
“ A fact which we have ourselves observed removes all doubts 
in this respect. A Brittany heifer, inoculated by us, communi¬ 
cated the peripneumonia to two others that were placed at her 
sides in one of the stables in the school at Alfort. The lesions 
characteristic of the malady were clearly shown at the autopsy in 
the lungs of these two heifers.”
