380 ON THE DISEASES OF THE HORSES IN CANADA. 
my observation. Blistering I find to be of little or no service. 
By perseverance with the iodide of potassium, and making use of 
the ointment, I have effected a considerable reduction of them, but 
have not succeeded in getting rid of them altogether. In a conver- 
sation I had with Mr. Turner, Y.S., in this city, a short time since, 
he informed me he had seldom seen the French Canadian horse 
affected with this disease, and that it did not commonly affect 
others until advanced in years, which I believe to be the case, 
having seen but few young horses with the glands enlarged. Out 
of eight pure Canadians belonging to the Field Battery at this 
station, five are affected, and two out of the five to such an extent 
as to render them very unsightly, but without materially incon- 
veniencing them. The youngest of these horses is thirteen, the 
oldest sixteen years of age. 
Mr. Turner has in several instances effected a complete removal 
of the enlargemeijits with the hydriodate of potash ointment. In 
one case the glands were as large as a man’s fist, on both sides, 
and very much interfered with respiration : it was an old horse, a 
great favourite with the owner, who informed Mr. Turner that the 
glands had been in that enlarged condition ten years. Notwith- 
standing, at the end of three months a perfect cure was accom- 
plished. 
On my arrival in this country I was, I must confess, surprised to 
see so many horses with this disease. Out of sixty horses be- 
longing to the Field Battery here, one-half of them had the glands 
more or less enlarged. In the Field Battery at Kingston, 180 
miles west of Montreal, only one-fourth ; and in the Battery at Lon- 
don, 3*20 miles from Kingston and 500 from Montreal, only six 
out of the same number. At Kingston the winter is much less 
severe than at Montreal, and at London a great deal less so than 
at Kingston ; from which one would be inclined to infer that in- 
tense cold, or iced or snow-water, has something to do with its 
production : at all events, there is something more favourable to 
its production in Lower Canada than at either of the stations in the 
Upper Province. 
SWINEY, SWINY, or SwiNNEY. 
This is a disease (if such it be) peculiar to the imagination of 
the inhabitants of Upper Canada, it never being heard of in the 
Lower Province. It consists in a shrinking or wasting of the 
muscles of the shoulder or shoulders. In the summer of 1845, 
when purchasing horses for the artillery, I went to look at a black 
colt, which I understood was for sale, but was informed he had 
got the swinney. On proceeding to the house of the owner, he
