CONTAGIOUSNESS OF STRANGLES. 
401 
although some came 500 miles, never had strangles after joining ; 
the excitability had been exhausted previously by having had 
fever and strangles in some form while at the remount depot. 
I was two years with the body guard without having cases of 
strangles; but the horses had farcy and glanders without my seeing 
the fever, the cause, no doubt, being the stables the horses were 
in when on duty. 
I was five years at the Hi par stud, where there were fifty 
English and Arabian-bred mares: the produce, between sixty and 
seventy per cent, annually, remained at the stud. I remarked 
strangles did not attack all the young animals, appeared at no 
particular season of the year, at all ages, from three months to 
four years old; and it appeared one or two years running, and not 
afterwards for the same period of time. 
While the colts remained isolated at this stud, or at the breeders’ 
in the province, strangles did not usually attack them; neither did 
it from the change in the mode of feeding and management imme- 
diately after purchase. It did not attack all the young animals, 
but individually at uncertain intervals, in general a few months 
afterwards, when a 'plethoric slate of the system was seemingly 
induced; thus a two-year-old purchased with yearlings would have 
fever and strangles singly, among two year-old colts that had been 
a year at the depot; and it happened without relation to season, 
but it was more frequent in the hottest and rainy seasons, (as 
shewn by the return), when fever of any kind was most likely to 
appear. 
On consideration of the whole of these facts, I am led to infer, 
with Sollysel and others of the same opinion, that horses “ must 
have it once in their lives.” That all young animals are subject to 
a similar kind of fever, from predisposition in the young animals’ 
organization, from delicacy of the tissues. I have watched the ap- 
proach of fever in colts, treated the fever to prevent the local affec- 
tion, and the animals thrived afterwards, as well as if the latter 
had occurred; its doing so, however, is evidence of the crisis 
of the fever, and that the young may be considered safe; for 
when it was otherwise, they did not, in general, thrive, which has 
been often noticed by others; and attentive observation shewed 
that, in these cases, it had affected the respiratory organs; and 
while isolated in the hospital stable such colts would thrive and 
get into condition, but sometimes, on being returned to the crowded 
stable, would again repeatedly be returned to thehospital stable with 
hectic fever, which sometimes ended fatally, from abscesses in the 
lungs. However, the deaths were few, considering the climate ; 
about three or four per month during the hottest and rainy months, 
and then they occurred rapidly from pleuro-pneumonia.
