260 FROG PRESSURE SHOE. 
of yellow lymph, that often hung in strings half way to the 
ground. A change for the better immediately took place. The 
swellings on the belly and chest and the symptoms of peritonitis 
disappeared in four days. The lips of the wounds gradually 
approached each other, and united, and the colt is now in ex¬ 
cellent condition. The sheath is whole, but larger than in its 
natural state, and will continue so as long as the animal lives. 
DESCRIPTION OF A SHOE FOR THE COMMUNI¬ 
CATION OF FROG PRESSURE. 
By Mr . Friend, F.S., Walsall. 
In presenting you with the shoe which accompanies this, I beg 
leave to state to you, that, previously to using it in my own forge, 
I had never seen or heard of such an one by any chance; and 
though it is possible that such a shoe may have been used by 
other practitioners, yet I assure you it was with me a decided 
invention : and unwilling as I should be to arrogate to myself the 
merit of a discovery which to some individuals may not be new, 
yet, as I consider that I have seen considerable advantage derived 
from its use in my own practice, and as I am convinced that it 
will be entirely new to the greater part at least of the veterinary 
public, I feel glad to be able (through your kindness) to offer a 
description of it to my professional brethren; and I assure you, 
that it is with very great pleasure that I attempt to repay, in any 
slight degree, the benefit 1 have derived from numbers of them, 
through the medium of The Veterinarian. 
I believe it will be universally admitted that there are a great 
many cases where it is essentially necessary to give pressure to 
the frog; and that this can scarcely be done, in a variety of 
instances, without resorting to means more artificial than is 
afforded by the use of the common shoe. That excellent physi¬ 
ologist Professor Coleman particularly has seen the need of this ; 
and with the view to give this necessary degree of pressure under 
all circumstances, he invented a shoe which is well known to all 
veterinarians as his patent frog-shoe. Now, as I consider it 
necessary in some measure to contrast the one before you 
with that invented by him, I beg leave to preface my remarks by 
observing, that I entertain the highest possible respect for Pro¬ 
fessor Coleman; that I disclaim the most distant idea of placing 
myself in competition w T ith him ; that I offer this shoe as the result 
of an attempt to improve upon a principle I am proud to acknow-
