(that, of course, prior to 1862), and also of its ignominious 
failure in his hands ; and as I had no means of knowing that the 
failure arose from the operation being grossly wrongly performed, 
if I had any opinion at all, it was, I would say, an adverse one. 
In the year mentioned, however, and yearly afterwards up to 
1874, I had occasion to be in Australia, and had my attention 
drawn very strongly to the subject by Mr. Graham Mitchell. 
That gentleman was kind enough to furnish me with the fullest 
information with regard to it; more, he demonstrated its effi¬ 
cacy so convincingly that I have to acknowledge that it is entirely 
to him I owe the debt for any credit which has attached itself to 
my work here in Edinburgh. Mr. Mitchell, I believe, has to be 
credited with the honour of being the first uniformly successful 
practiser of inoculation, and has reaped his reward. 
I have now brought the sketch down to 1874, in which year I 
returned to this city ; and although I have almost immediately 
abundant opportunity of trying conclusions between inoculation 
and pleuro-pneumonia, I found the disastrous results obtained 
by G-amgee so vividly in the recollection of the dairymen that it 
was impossible for a time to get any one to permit of its re-trial. 
I must tell you I did not promise that the thing would be a cer¬ 
tainty, because my experience of it in Australia was derived 
from what I knew of its operation upon cattle living a natural 
life, under a very superior climatic and other conditions, in which 
respect they differed very materially from the great bulk of our 
subjects here, at any rate from my subjects—dairy stock—exist¬ 
ing under what may he termed high-pressure conditions. I 
know, however, that the disease abroad was the same as here, 
and was of opinion that if Mr. Mitchell’s method was adopted in 
preference to that of the Continent, that we would get Mitchell’s 
results. That my opinion was correct, has been fully and con¬ 
clusively verified. 
I have made an abstract of my last year’s work, and I find that 
I commenced to inoculate on the 1st of February, and I left off 
on the 18th of November. During that time I inoculated in 78 
different localities, all of which, with the exception of 51, were 
within three miles of this room. 
Of these places there were

The number of auimals inoculated was 1596, all of which, 
with the exception of 28, were milch cows. 
Of this number 1511 were inoculated when the disease was in 
the byres in which they were housed. 
46 had not been exposed for three months 
to an infected animal in their byres. 
21 had not been for six months.
