tempted to open his mouth. I then discovered that the os maxil- 
lare inferior was fractured, and, superiorly, the three near incisors, 
the tush, and two of the left molars broken, and only retained in 
the mouth by the muscles that were attached to them. There was 
no mark or wound externally. I dissected the tush carefully out, 
and removed two small splinters from the maxillary. I dressed 
the wound with tincture of myrrh, and gave Barbadoes aloes 3ii, 
and ordered him slop bran mashes: he remained in my stables 
until the 24th, when he was discharged. He could feed as well as 
formerly, and finish his rack of hay as quickly as any other horse. 
I could not account for the accident, as there was externally no 
mark of violence. 
A CASE OF LITHOTOMY ON AN OX. 
By M. JOUANAUD, M. V. at Saint Ceve. 
I WAS solicited, on July 23,1836, to attend to an ox, sadly poor, 
and that seemed to be afflicted with colic. Wishing to ascertain 
the nature and cause of the disease, I introduced my arm into the 
rectum. The bladder was in a state of great distention, and the 
ox made the most violent efforts to discharge his urine. I explored 
the urethral canal, and T recognized the presence of a calculus at 
the situation of the ischial arch. I immediately cast him, as gently 
as I could, on a good bed of straw. I effected an oblique incision 
on the urethral canal, and a granulated calculus, of a conical form 
and a metallic colour, was extracted through the opening. A little 
bloody urine followed through the incision. The hobbles being re¬ 
moved, the beast got up, and began to void his urine in abundance. 
He was put on a somewhat restricted diet, and mucilaginous 
drinks, in which a small quantity of nitre was dissolved, were ad¬ 
ministered. 
24/A.—The greater part of the urine escapes through the inci¬ 
sion, but a few drops find their way through the point of the penis. 
The animal seems to be but little affected by the operation. The 
nitrated drinks were given during seven or eight days*. 
Four months passed without the ox experiencing any difflculty 
in voiding his urine ; but then came a new attack of colic, with re¬ 
tention of urine, and he was sold to the butcher. 
* These nitrated drinks appear to me to be contra-indicated in a case like 
this. The author probably sup[)oscd that there mif^ht be some smaller cal¬ 
culi in the bladder, and increased the urinary secretion with the hope of 
their being thus expelled.—F/'c/icA Editor.
