PANICS AMONG HORSES.

And though this membrane is the usual generator of the 
hoof, yet it must be looked upon as in reality more the regu- 
lator or constructor of that envelope than its creator — dis- 
posing the cellular elements thrown out from its surface 
in the form of fibres and leaves ; whence the imperative 
necessity, says Professor Gourdon, that in all the operations 
performed on the foot, the various constituent parts of this 
apparatus should be preserved as scrupulously as possible, its 
integrity being the primary condition of a sound and well- 
formed hoof. 
Having discussed the formation of the hoof, and the share 
taken by the living structures of the foot in that process, we 
have now to speak of its growth. 
Much pertaining to this division of the subject has, how- 
ever, been already incidentally touched upon, and if it were 
not for the important relation it bears to the art of farriery 
and the general management of the organ, but little more 
would require to be added. But these reasons are so weighty, 
and yet are so apt to be overlooked, that it is considered 
necessary and desirable that the question of growth should 
be examined at some length, in order that we may arrive at 
definite conclusions as to the manner in which it is carried 
on, and the rules that ought to guide us in controlling it, so 
as to maintain foot and limb in a proper state of relationship 
to each other and to the ground.

PANICS AMONG HORSES. 
By G. Fleming, M.R.C.Y.S., Royal Engineers. 
I am induced to offer some further remarks on this inter- 
esting subject, in continuation of those which appeared in last 
month’s Veterinarian , in consequence of an account of a 
panic on a large scale having occurred at St. Petersburg 
among the horses of a cavalry regiment, about the same time 
as that of the 1st Life Guards at Aldershot. This account, 
and other noteworthy remarks which will be alluded to, is 
from the pen of Colonel Money, and appeared in one of a 
series of excellent letters on the “ Campaign of St. Peters- 
burg,” published in the Times for October 2nd. The letter 
was dated from St. Petersburg, September 20th, 1871. The 
colonel’s description is so graphic and instructive that I 
make no apology for giving it in his own words. He 
writes :
