IX. DISEASES OF THE FEMALE ORGANS 
. OF GENERATION. 
As the greater number of these diseases are considered in works on 
special pathology and obstetrics, only a short account of those which 
necessitate surgical interference is here given. 
L—INJURIES AND INFLAMMATION OF THE YULYA, 
YAGINA, AND UTERUS. 
In cows, the labia pudendi are most frequently injured by horn- 
thrusts ; in mares, occasionally, by the shafts of vehicles; in all species 
of animals by violent and unskilful manipulations during delivery. In 
such cases rupture of the perineum is common. In cows, the vagina is 
sometimes wounded, though seldom seriously, by the application of the 
vaginal truss for the purpose of retaining the prolapsed vagina or 
uterus; sometimes, however, severe croupous inflammation results, and 
extends over the vagina. These conditions seldom require surgical 
interference, and must be treated on general principles. Sometimes 
wounds require incising to allow of better drainage; sometimes healing 
can be assisted by carefully applied stitches. Wounds in this region 
most frequently result from rupture of the perineum. When fresh they 
should be accurately sutured ; when of old standing the edges may 
require to be freshened. 
Extensive wounds and excoriations of the mucous membrane of the 
labia pudendi may lead to occlusion of the vulva. Apropos of this, the 
following case may be quoted :—An eighteen months filly exhibited 
occlusion of the vulva from its upper angle as far almost as the clitoris, 
where an opening the size of a goose-quill remained, from which urine 
was discharged in a thin stream. The adhesion was divided; but as it 
recurred several times, it was found necessary to pass the hand into the 
vagina daily and dilate the vulva. Under this treatment perfect recovery 
occurred. 
Occlusion of the vagina, due either to persistence of the hymen or to 
adhesion of the surfaces of a vaginal wound, has been seen in the 
cow and mare. In either case the os uteri is not attainable, and a
