LITHOTOMY IN A GELDING.

“The number of the injections should vary with the number of 
the fistulse, with their size and depth ; but, as a general rule, they 
should be renewed every day, and in quantity sufficient to wash 
completely all the cavities by which the cartilage is traversed. 
“ The effect of the injections is during the first eight days to 
render the suppuration more abundant and whiter. The tumour 
simultaneously softens and contracts, and the lameness diminishes. 
“The signs of cure are either a slight hemorrhage at the close of 
the escharotic injections, or a difficulty in pushing them into the 
fistulous orifices.” 
A large number of intractable cases have been radically cured 
here by this process in from fifteen to twenty days’ time. As I have 
repeatedly witnessed the almost miraculous effect of the Liquor of 
Villate, I do not hesitate to send you this sheet, in the hope that 
similar experiments may prove equally successful in England. The 
“Recueil de Medicine Veterinaire,” for June 1847, just published, 
contains an elaborate article upon this matter, from the pen of M. 
Henri Bouley.

TWO IMPORTANT CASES. 
Communicated by WILLIAM FIELD,- Esq. 
I. — Lithotomy in a Gelding. 
A GREY gelding, aged, the property of C. Smith, Esq. of Bal- 
ham, Surrey, was sent into Mr. Field’s hospital for horses on the 
28t,h July last. The symptoms being unequivocally those of stone 
in the bladder , Mr. Field determined at once on the operation. 
Accordingly, after some two or three days of preparation, the 
horse was cast and secured in the manner usual for lithotomy, and 
went through the operation without any thing extraordinary occur- 
ring : the casting and liberating and operation, altogether, not 
occupying more than twenty minutes. 
This being the sixth case on which Mr. Field has operated, five 
out of which have proved successful, and his mode of operating 
being as simple as it is effectual and safe, it may be desirable here 
that we should briefly run through its details. 
For the male subject he needs no more instruments than staff, 
scalpel, and forceps ; for the female, forceps only : nor does the 
latter require to be cast for the operation; it being most conveni-
