VESICAL AND BILIARY CALCULI.

about in walking ; the croup was in continual motion, the flanks 
tucked up, but not agitated, the dorsal spine slightly arched, 
the pulse hard and full, and the artery rolling. The interior of 
the rectum felt extremely warm; pressure on the bladder from 
below backwards caused the expulsion of half-a-pint of clear 
urine. 
Waiting for symptoms more characteristic, I ordered venesec¬ 
tion, emollient clysters, spare diet, water gruel, &c. 
On the night of the 8th the animal, in spite of every effort to 
maintain the erect posture, sank down upon the litter, in which 
-position she ate and drank as before. Two days afterwards in 
consequence of contusions received she was suspended. 
The same day the owner informed me that the mare had been 
making constant efforts to stale without being able to posture 
herself, and that only a vtfty small quantity of urine passed 
every time ; also that these efforts were preceded by spasms and 
frequent sweats along the flanks, whose motions had become 
accelerated. 
These fresh symptoms directed my attention to the bladder; 
I carried my hand into the vulva and introduced the index finger 
into the meatus urinarius, and discovered within the bladder a 
semi-solid terreous mass occupying the whole inferior part 
of it. 
I tried to attenuate this collected matter by injections of warm 
vinegar and water, but ineffectually ; I therefore introduced a 
spoon into the meatus urinarius and succeeded in extracting-one 
pound ten ounces of terreous substance of a yellowish cast and 
a strong infectious odour. 
The bladder being almost empty, I found by the touch that 
there were several exulcerations in the lower part, and that por¬ 
tions of the mucous lining were floating within the cavity. I 
injected into the bladder a decoction of mallows in vinegar, and 
prescribed clysters and spare diet. 
On my next visit, on the 11th, I found the genitals greatly 
tumefied, their mucous lining highly inflamed, and the pulse in¬ 
creased in strength. Also, occasional slight colics ; frequent 
horhorygmi; bladder full; urine discharged by light pressure, 
very thick and of a yellow colour. 
These symptoms were owing to the irritation occasioned by 
the frequent introduction of the fingers, spoon, and syringe into 
the bladder ; the colic I ascribed to the propagation of the in¬ 
flammation to the peritoneum and intestines. Diluents, fomen¬ 
tation, soothing lotions.
