REPORTS OF OASES.

the tumor was easily reducible and evidently contained some 
fluid. On replacing the tumor, I found no opening beyond, 
the meatus urinarius, and that the vagina ended in a blind 
pouch, consequntly I diagnosed an imperforate hymen. I drew 
the hymen to the surface again and opened it freely with a 
crucial incision. Quite an abundant discharge, yellowish and 
viscid, came away after the incision was made, which I diag¬ 
nosed as a part of the vaginal and menstrual discharges which 
were unabsorbed and had no means of exit. The hymen was 
a strong and unyielding membrane and nearly as tough as 
ordinary integument. 
EQUINE SYPHILIS ? 
By W. R. Claussen, Y.S., Waupana, Wis. 
Some time in May I was requested to see a Percheron 
stallion, property of Mr. R. A. Amherst. On examination I 
found the penis and prepuce swollen and covered with ragged 
chancre-like sores, also a slight, inoffensive mucous discharge 
from the urethra. To my inquiry I was told that the animal 
the week previous had served twenty-three mares in three 
days, had appeared all right till that morning, when Mr. R. 
first noticed the sores and swelling. I felt satisfied the sores 
must have been in existence for some days, although the man 
in attendance insisted that the horse was “in the best kind ” 
of shape the evening before. The temperature was normal 
and the appetite good. I termed the disease chancroid. I 
have afterwards found in one of Professor Anacker’s works, 
mention of blennorrhea urethrae. Professor Anacker asserts 
the disease may be produced by mechanical irritation from 
excessive coition or by the introduction of some foreign body 
in the urethra, either from the bladder or from without, first 
as a simple urethritis, the irritation later on spreading to the 
glans penis and prepuce. The authorities at my disposi¬ 
tion do not mention the disease as contagious only from fe¬ 
males to males, but I must regard it as otherwise, for a few, 
(seven or eight) mares that had been served during the three 
days previous to my visits to the stable, and the only ones
