TREATMENT OF THE HORSE IN THE AUTUMN. 627 
the first intention, from any circumstance or neglect, is a frequent 
cause of inflamed vein. Peculiar idiosyncrasy I believe to be the 
next most fruitful cause of phlebitis. 
Horses that have lost a vein swell about the head during the 
first summer that they are turned out. They occasionally do so in 
the ensuing one, but only in a moderate degree. After a lapse of 
time scarcely any ill effects remain, and the loss cannot be dis¬ 
covered except by close inspection; neither should I object to a 
horse on that account, for any work, either as a hack or farm-horse. 
ON THE TREATMENT OF THE HORSE IN THE 
AUTUMN. 
By E. Gabriel, Esq., M.R.C.S. 8^ V.S., London. 
Among the many interesting topics Avhich engage the attention 
of the philosophic inquirer into natural history, one, and certainly 
not the least interesting, is the contrivances to which nature has re¬ 
course to enable animals to bear the variations of the temperature 
by which they are surrounded. The power of supporting life under 
any considerable alterations of heat and cold is possessed by different 
animals in very different degrees. Some can exist only within the 
tropics, others are capable of adapting themselves to a more ex¬ 
tended range of temperature; while to many the frequent and try¬ 
ing variations of a climate like ours appear to produce but a very 
temporary inconvenience. Migration, torpidity, and variation of 
clothing, appear to be the three principal means by which this 
end is obtained. Of the two first it is unnecessary here to speak; 
but the third, that is, the change of clothing, may not form an unin¬ 
teresting subject for a few remarks, particularly at this season of 
the year; more especially as we shall find that condition—that all- 
important object with the horseman, the veterinary surgeon, the 
ignoble groom, and the noble owner—is in no slight degree de¬ 
pendent on it. 
It cannot have escaped the notice even of the most careless ob¬ 
server, that very considerable changes take place in the appearance 
of animals at those seasons when the great transitions from heat 
to cold and the reverse set in, but more particularly the former. 
The cause of this is, the demand made on their constitution to make 
provision for the change of temperature, without which they would 
not be enabled to bear the cold of winter—without which they 
could not even exist in a natural state in severe seasons. If we 
take any class of animals, as, for example, sheep, swine, cattle, or 
liorses living in a warm climate, and compare it witli the same 
class living in a cold one, we shall find very considerable dif-
