PREVENTIVE INOCULATION - 67 
pup had no reaction ; consequently, at the end of three 
weeks, I again injected a larger dose, which reacted only 
very slightly. 
“Some six months later ] bought (unwittingly) a bitch 
with distemper, and she ran at exercise with the before- 
mentioned puppies. All these took distemper, but were 
only slightly ill for about a week (discharge from eyes 
and nose, slight cough, slight diarrhoea, temperatures 
from 102° to 103° F.), but at the end of the week were 
perfectly well again. The whole of that litter is alive 
now ; all have been exhibited, and two are frequently at 
shows, yet none have ever had any further signs of dis- 
temper, and I have several times had distemper dogs in 
the kennels. 
“T think, therefore, in showing that in my own kennels, 
in the frst five years of breeding, without inoculation, the 
mortality from distemper was at the rate of over 50 per 
cent., whereas in the /ast five years, with inoculation, the 
mortality is only 2 per cent., there is very little room 
for doubt that we must look to inoculation to help us 
against the scourge of the kennel-distemper.” 
About this time Mr. Stewart Wood, M.R.C.V.S., testified 
to having inoculated sixty-nine dogs with Copeman’s vac- 
cine during the past few years, the majority of which only 
received one injection. To his knowledge only five of 
them subsequently had distemper, of which two died. 
This, however, is no reliable or true test, as he does not 
state whether any of the dogs had already acquired an 
immunity, nor does he actually know whether any of the 
remaining inoculated dogs contracted the malady or not. 
‘The most recent testimonial which has come into my 
hands by the courtesy of Dr. Copeman is a letter received 
by the Jenner Institute in October, 1920, from His Grace 
the Duke of Beaufort. It runs as follows: “ The Duke 
of Beaufort, on the recommendation of Dr. Monckton 
‘Copeman, inoculated his entry of 18} couples as they 
came in from ‘walk’ last spring (two inoculations), and 
up to the present time they have shown no symptoms of .
