A. 0. ALVERSON. 
ing, was showing some slight pain, evidenced by kicking or 
stamping with the hind feet and switching the tail. Pulse, 
respiration and temperature nearly normal. 
Showed a dirty, gummy appearance of the hair down the 
back part of fore legs and along the median line of belly, ex¬ 
cept for a foot or so forward from the sheath, to which point 
the hair was nearly gone, and the skin somewhat excoriated. 
This led to an examination of the penis, which was swollen 
or enlarged at lower end, and showed soreness around the 
urethral opening. 
Then examined the horse per rectum and found the blad¬ 
der did not contain any great amount of urine. 
Diagnosed some obstruction of urethra, which could only 
be permanently relieved by operation. Saw no urgent neces¬ 
sity for temporary relief by use of catheter, with some urine 
dribbling away all the time and the bladder not distended. 
The owner thought he would ship the horse as he was 
and take whatever he could get. The next morning the 
animal was brought to the infirmary in a dying condition. 
However, tried to pass the catheter and found the urethra 
plugged with a deposit of lime salts (sabulous deposit). Re¬ 
moved considerable of it, as far as in reach, then passed a 
metal sound to pave the way, so to speak, and then succeeded 
in passing catheter, but no urine came. Animal died in a 
short time and autopsy was made the next morning. 
Nothing abnormal until reaching urinary organs. Up a 
little more than a finger’s length in the urethra was a iarge 
mass of the same deposit. Bladder nearly black, had numer¬ 
ous adhesions to the pelvis and pelvic viscera, contained a 
hole two or three inches in circumference, and internally was 
studded with the sabulous deposit. 
No. 2. Called morning of October 14, 1891. Found pa¬ 
tient, a two-year-old grade draft gelding, standing in a box 
stall, showing marked symptoms of depression. 
Temperature hardly up to normal, pulse about forty per 
minute, head held low, eyes dull, and breathing deep and slow. 
A very foetid odor came from the mouth. Diagnosed as 
brain trouble, probably caused by indigestion.
