any in the bladder, but used the catheter as a sound. On enter¬ 
ing the bladder the catheter came in contact with a solid body. 
There was no urine in the bladder, and on tapping the foreign body 
the characteristic sound and feeling was transmitted by the metal 
catheter. Withdrawing the catheter I first emptied the rectum? 
and then made an examination per vagina, and found that the 
stone was freely movable within the bladder. I then attempted 
to dilate the meatus, and in a short time yas able to get three 
fingers into the opening. 
But the expulsive efforts became so severe that I gave another 
hypodermic of gr. ii. morphia. Then with my left hand in the 
vagina, I introduced with my right a pair of long-handled forceps. 
Pushing the stone within the spoon-shaped jaws of the forceps 
with the fingers of my left hand, 1 with some trouble removed 
it. The irritation caused such expulsive efforts that I feared 
eversion of the bladder. Telling the assistant to pinch the mare 
across the loins, I threw into the bladder an injection of hot 
water. The injections were not long retained, but they served 
the purpose of allaying the irritation and washing out the bladder. 
The removal of the stone had caused some bleeding, but it soon 
stopped, and I used injections of warm water and tr. opii. As 
soon as the expulsive efforts had subsided sufficiently I made an¬ 
other examination. Found no gravel, but as far as my finger 
could reach the mucous membrane felt thickened and spongy. 
After waiting a short time, I again injected into the bladder 
water acidulated with nitric acid; put her in a warm stall with an 
extra blanket across her loins. As long as she manifested any 
irritation of the parts she received tr. hyoscyamus ^ ss. in Oi 
flaxseed tea every two hours. 
Light and soft feed. In a few days she resumed her work 
with no further trouble. The stone is spherical and slightly 
flattened. Dark, reddish brown externally, but showing a dark 
mulberry-shaped centre, where the jaws of the forceps have re¬ 
moved the outer incrustation. The centre is hard, but the outer 
covering roughened, and appearing as little tubercles, is easily 
broken away. 
This external covering, or more recent deposit, is one-eighth
