organ. All the animals inoculated preserved perfect health , and those in¬ 
tended for butchering never stopped laying on fat. 
Mr. Gamgee says: “Another objection, which has led of late 
years to the practice being checked among the cow feeders of Brook¬ 
lyn, is the sloughing of the tail, and the animals splashing blood and 
matter from their sore tails into the milk cans. All this arises from the 
operation being performed by persons who know nothing of the pre¬ 
cautions to be used, and especially of the proper selection and pre¬ 
servation of the virus. Accidents will happen, but out of nearly two 
thousand inoculations, I have had a loss of less than one per cent, by 
death, and under five per cent, of the tails have lost their tips.” 
If properly performed, then, we may add, inoculation has no influ¬ 
ence on general health of the animal ; it may be performed on milking 
or fattening animals without prejudice to their appetites, or even on 
cows about to calve, without danger. 
THE ADVANTAGES OF INOCULATION. 
Inoculation is now resorted to in nearly all countries to stop the 
losses from this disease ; and it has proved by far the most success¬ 
ful means of combating it, excepting, of course, the slaughter of in¬ 
fected animals, and disinfection and isolation of infected prem¬ 
ises. Gamgee says : “ It is impossible, and indeed it would be su¬ 
perfluous, to give a detailed account of the thousands and tens of 
thousands of cases which have led to the almost universal opinion 
that inoculation is the best means in the majority of instances to 
check the ravages of pleuro-pneumonia.” Dr. Roll says: “Persons 
who have had occasion to make observations in countries where the 
disease is present almost continually, as Belgium, Holland, parts of 
Italy, and Northern Germany are almost all favorable to inocula¬ 
tion, and say that since it has been practiced, districts and stables 
which were formerly never free from the disease, have been completely 
delivered from it, and that it is excessively rare that an animal inocu¬ 
lated with success is attacked with pleuro-pneumonia.” M. Boulay, 
from whom I have already quoted at length in regard to the outbreak 
of ISo), in France, say, in regard to inoculation as a'means of com¬ 
bating the disease, “Our success was complete.” Only one or two per 
cent, of the animals successfully inoculated contract pleuro-pneumonia 
afterwards, if exposed to the contagion. 
It is a matter of national importance that the extension of this 
disease be checked at once, and I have written thus at length in regard
