22 DIVISION OF THE SACRO-ISCHIATIC LIGAMENT.

I directed succulent diet to be allowed, and during the next 
few following days gave her a little tonic medicine. The 
small orifice I had made jvas cicatrized over on about the 
third day, and I had the satisfaction of seeing the animal 
perfectly recovered in far less time than I had expected. 
I would not be thought to attach more importance to this 
one case than it really merits. The repetition of the opera- 
tion may, perhaps, be again and again called for- before its 
perfect safety is established. It may also be that others have 
resorted to it already, although they have not given publicity 
to the fact, as Mr. Varnell, I am informed, has long taught 
its practicability; and “Facile est inventis addere.” There 
may be, moreover, objections to it that I am not acquainted 
with, since “ every medal has its reverse.” My object has 
been simply to make knowrn an operation which, in extreme 
cases 3 appears to me likely to prove advantageous, by saving 
the life of a valuable animal, as well as its offspring. Further, 
it possibly might admit of adoption in the human subject ; 
since surely it is not more formidable than the Caesarian 
operation. Here, however, I speak with great diffidence, not 
being competent to contrast the two operations. 
EXPLANATION OE PLATE. 
A. The last bone of the sacrum, to which that portion of the ligament in- 
tended to be divided is attached. 
B. The sacro-ischiatic ligament. The dotted line indicates the place 
where the section is to be made, but which should be carried a little 
further than to where the dots extend. 
C. That portion of the ischium to which the ligament is strongly attached. 
The artist has unfortunately made the sacro-sciatic ligament, as a whole, 
too formal. Two openings should also have been left ; one anteriorly, 
for the passage of the gluteal vessels, and one behind the acetabulum, 
for the passage of the sacro-sciatic nerve, and the tendons of the 
obturator interims and pyrofonnis muscles.
