IMPERFORATE HYMEN—TWO CASES: ONE IN A MARE, 
THE OTHER IN A COW. 
By Prof. Degive. 
First Case .—When laying down, a red tumor, with its mu¬ 
cous covering, mistaken for the vagina, is observed in a seven- 
months-old fillv. The examination revealed the following 
•j O 
conditions: The animal standing up, nothing abnormal is noticed 
on inspecting the vnlva. Introducing the hand into the vagina, 
beyond the meatus urinarius, is felt a true septum, completely 
imperforate, placed on the limit of the vulva and vagina, which 
must be the part noticed for a prolapsus vaginse. Trying to 
lacerate it with the lingers, and failing in the attempt, the animal 
is thrown down, and as soon as she is in the recumbent position, 
the tumor makes its appearance. It is round, of the size of an 
apple, and protrudes through the vulva. Its surface is covered 
with a mucous tegument of a pale color ; it lias the feeling of a 
pouch, with thin walls, and is in continuity with the walls of the 
vagina; it also seems to have fluid or moveable contents. The 
membrane being divided, and then excised, a certain quantity of 
viscous, pale, greyish fluid escaped. The mare had no further 
trouble. 
Second Case .—A yearling heifer has for several days made 
slight expnlsive efforts; her appetite has diminished ; the excre¬ 
ments are hard and coated. Several days after her efforts at ex¬ 
pulsion have increased, with nearly complete loss of appetite ; 
fceces hard, coated, and sometimes bloody ; urine very ammonia- 
cal, and dropping with each expulsive effort. Suspecting a tu¬ 
mor or an abscess of the pelvis, rectal examination is made. A 
long, ovoid tumor is then felt, extending from the posterior part 
of the pelvis forward in the abdomen. The finger, introduced 
into the meatus urinarius, enters with difficulty, being compressed 
by the tumor. Vaginal exploration shows this tumor to be soft, 
hemispherical, and situated immediately in front of the urinary 
meatus. The posterior wall of this tumor is formed of two mem¬ 
branes ; the posterior is incomplete, and has two oval openings,
