he has himself observed where inoculation has not been resorted 
to, I think he has every cause to be highly in favor of the same.” 
At a meeting of the Central Veterinary Union of Saxony, a 
very trustworthy veterinary authority says : “ That after careful 
observation, he was ready to affirm that inoculation was 7iot only 
strongly justified , in regard to the combatting of this disease , but 
it is also the duty of every man to do his best to see it executed .” 
Rimpau says further: “We must also emphasize, that the 
friends of inoculation among the veterinarians do not by any 
means assert that the same is an unconditional means of protec¬ 
tion for the inoculated animal against infection from 4 Pleuro¬ 
pneumonia erysipelatodis.’ So far as my knowledge extends, all 
concede that protection first begins when the action of the inocu¬ 
lation has begun; i.e ., the phenomena necessary to the same have 
become apparent at inoculation’s point, and when the animal has 
not in the intervening time become the subject of the disease, let 
the latter be apparent or not.” According to this view then, 
those cases of disease which come to pass by inoculated animals 
within from four to six weeks from time of inoculation, cannot be 
looked upon as proof against the protective power of inoculation \ 
they are much more to be looked upon as indicatory of the un¬ 
timely recognition of the pest which had already gained consider¬ 
able extension in the herd at the time of the inoculation, or that 
the contagion has affected many animals concomitantly. Further, 
most “ Impfartze,” (inoculators), concede that cases come to pass 
where inoculated animals become subjected to the natural disease 
several months after the same has taken place, and that in all 
cases the inoculation does not provide absolute protection, although 
the phenomena necessary to the action of the same have been appa¬ 
rent ; on the other hand, they assert that such cases are exceed¬ 
ingly scarce, and that inoculation may always be considered as 
offering an important degree of protection against the natural 
disease. Rimpau also gives expression to very justifiable doubts 
with regard to the trustworthiness of the statistics and statement 
to be found in this regard in the “ Mittlieilungen aus der tliier- 
arzt lichen Praxis im preussischen Staate,” the same being inex~ 
act: In order that such should be trustworthy it is necessary that
