74 CANINE DISTEMPER 
up to this day has not been a subject of distemper. 
Dog now three years old. 
Case 4.—Fox-terrier, 6 months old. 
Case 5.—Fox-terrier, 2 months old. In both these 
cases only slight disturbance of health was noticed, and 
after a suitable period of isolation they were returned to 
their owners. I heard nothing more of them, and pre- 
sume if they had caught distemper I should have been 
notified. 
Case 6.—Pekingese, 3 months old. In this case the 
reaction was mostly confined to the seat of inoculation, 
as a painful swelling appeared about twelve hours after 
injection, but subsided without bursting before three 
days had elapsed. The dog was disinclined to feed 
during this period, but gradually regained its normal 
health. Some months later I was requested to attend it, 
and found it suffering from unmistakable distemper, with 
which it was seriously ill for more than four weeks, and 
was saved only with great difficulty. 
Case 7.—Irish terrier, about 5 months old. There 
was practically no disturbance of health following the 
injections, and I never was acquainted with any occur- 
rence of illness in after years, although I knew the dog 
up to the age of quite four years. 
These few observations cannot be regarded as a 
reliable proof of the efficacy of the bacterin, as the 
dogs’ previous and subsequent histories were somewhat 
obscure; though it may be noted that in no case did any 
untoward result follow the inoculations, and that in 
Cases 1 and 6 no immunity was conferred. In each case 
the dog had not previously suffered with distemper so 
far as the owner could say, and although it might be 
unfair to presume that one or all of them had already 
acquired an immunity, yet the possibility of such a con- 
tingency must not be lost sight of. From these few 
cases I drew rather favourable deductions, and shall at 
least pursue the use of this prophylactic in practice on 
every possible occasion, as it seems to show promise
