also the stable. I found they had thirteen horses in the stable ; 
they had replaced these thirteen horses twice over in seven months, 
that is, they had taken them out, horse by horse, as soon as they 
had become attacked, both seasoned and unseasoned horses alike, 
and sent another horse to work in its place. The majority of the 
horses so taken out had died, or had been sent to the dogs. I 
found the stables perfectly sweet, scrupulously clean, both floor, 
mangers, boskins, buckets, gears, grids, gutters, &c.; the horses also 
were looking well, and in a good healthy condition. They had used 
whitewash and disinfectants very freely, and had removed the sick 
horses at once as they were attacked, but all these precautions 
proved utterly unavailing in arresting the disease. I would here 
remark that unfortunately aerial poisons are perfectly inodorous. 
I strongly recommended a free ingress of air by making a hole 
in the wall on the ground surface a foot square for ingress of fresh 
air, and improved ventilation at the top; and also ordered two fires 
put into it for two hours a day for a fortnight. This was done at 
once, and from that day up to the 1st of May, 1871, when I called 
there, they had not had a single horse attacked with the disease. 
They had had one or two horses with simple sore throats eight or 
ten months after, but these were only temporary cases. Here we 
have, I think, evidence of an irresistible kind, showing that the 
cause, whatever it might have been, was at once removed. I called 
them cases of putrid fever, produced by inhaling a putrescent air, 
though this state of the atmosphere was utterly imperceptible to the 
senses. But further than this, there were under the same arch, and 
the arch adjoining it, which was open with this arch by an arch 
between them, eighty horses belonging to Messrs. Chaplin & Horne ; 
these horses have been replaced three times over in two years, in 
the same manner as the horses above alluded to. I recommended 
the same course to be adopted in that stable, but the authorities of 
that firm only ridiculed and poo-pooh’d it ; they remarked, we might 
as well light a fire on the top of Chalk Farm hill for what good it 
would do. Well, observe the consequence ; during the following six 
weeks they had six horses attacked and taken away out of the 
stable. They then adopted the method recommended by me, and 
from that day they have not had one horse attacked. Of the 
one thousand and odd valuable cart horses under my care belonging 
to the above three companies, we do not loose from sickness more 
than 1^ or 2 per cent, per annum, taking one year with another. 
The fourth example refers to the horses belonging to the Corpo¬ 
ration of the City of Manchester. During last summer and autumn 
a very malignant enzootic was raging in their stables in Water 
Street. In August, the practitioner attending to them met me and 
invited me to go with him and see them. He showed me numbers 
of cases there on hand, some of them in a hopeless state, and took 
me through the stable, but did not on this occasion ask me for my 
opinion or advice, neither did I venture to obtrude it. On the 17th 
November I received a note from him requesting my attendance to 
make a post-mortem examination of a horse from the Corpo-
