268 VETERINARY SURGICAL THERAPEUTICS. 
rupture of the aponeurosis of the fascia data, Various ways have been 
recommended. Some operate upon the animal standing, others while it 
is down. Quiet animals should be placed in stocks, others must be 
cast and secured. Dorfeuille, Castex, Cruzel, Bernard, Ringuet, Lafosse, 
and Boiteau have described the technic of the operation.

external ischio-tibial muscle. (2) Fascia lata (Cruzel and Pench). 
Two conditions present themselves: one in which the animal is thin, 
and the cord formed by the anterior border of the ischio-tibial is promi- 
nent and easily felt; the other in which the subject is in good condi- 
tion, and it is difficult to locate the situation of the parts. In the first 
case, the section must be made subcutaneously. At eight or ten cen- 
timeters below the trochanter, the operator plunges obliquely the straight 
bistoury under the projections made by the anterior border of the 
muscle; and after a quarter-circle movement he draws it outwards, 
dividing the aponeurosis and the anterior border of the muscle. If the 
regularity of locomotion has not returned, the instrument is introduced a 
second time and the division completed. When the operator does not 
feel clearly the anterior border of the muscle, he must, on the same stop
