Vesical Calculus in a She Ass [By Schimmel '].—The 
animal was in good condition, and presented the following symp¬ 
toms : frequent and severe efforts to micturate, accompanied by 
partial protrusion of the rectum and vagina, and followed by the 
emission of a small quantity of cloudy mucoid urine. On ex¬ 
ploring through the vulva, the vagina was found the seat of warm 
cedematons infiltrations, the meatus nrinarius was widely di¬ 
lated, a calculus was felt extending forward on the upper face of 
the bladder, to which it was adherent. The removal of the 
stone was quite difficult; the animal had to be thrown and the 
crushing forceps used. During the severe manipulatious, the 
membranes of the bladder were torn and as a consequence escape 
of urine into the abdominal cavity took place and death was the 
result. At the post-mortem, there was found chronic inflammation 
of the bladder, with thickening and induration of the wall, ex¬ 
cept where the calculus rested, where the walls were very thin. 
The right kidney was affected with interstitial nephritis, the left 
with hydronephrosis. The calculus weighed 197 grammes ; its 
surface was porous, its color dark brown ; it seemed made by the 
adhesive union of several small calculi. 
Uterine Fistula [By Beer \.—A milch cow, four years old, 
since her last calving is losing flesh at sight; she has, in the 
lower part of the left flank, a piriform tumor, elongated from 
above to below, from forward backward, fluctuating, yet giving 
no fluid with exploring needle ; this tumor is surrounded by large 
cedematons swelling. Desirous of waiting for developments, 
the author advised embrocations of laurel oil. These were fol¬ 
lowed by an increase in the local symptoms and the appearance 
of general manifestations ; anorexia, fever, and an enormous de¬ 
velopment of a subcutaneous emphysema, extending far from 
the primitive dimensions of the tumor. The animal was de¬ 
stroyed. At the post-mortem there was found : an intimate adhe¬ 
sion of the uterus with the walls of the left flank and in the 
centre of this a fistula, opening at one end in the uterus, at the 
other towards the mucular layers of the flank; the uterus was 
filled with a yellowish-red fluid, which escaped through the fistu¬ 
la between the muscular layers. To explain the cause of this 
lesion the author says that for him the left ovary was first suffer¬ 
ing with tuberculosis; that this spread and involved all the in¬ 
ternal genital organs and gave rise to the adhesion of the uterus 
to the flank. As sequelae of the morbid process, tuberculous -
