DISEASED BLADDER OF THE HORSE.

contractility entirely lost. At this stage I called in my 
friend Mr. Lawson to see the case. He carefully examined 
it, but he could detect no calculus. There being perceptible 
a slight thickening about the neck of the bladder, he recom¬ 
mended the application of iodine over the course of the 
urethral canal, as near to the neck of the bladder as pos¬ 
sible. This was done for some time, but with no advantage. 
During this time the horse’s appetite became precarious, and 
his general health appeared to be suffering, the pulse being 
above 60, and it became evident that something else must 
be done, as under the present treatment he was only getting 
worse. The urethra also was becoming tender and sore 
from the frequent use of the catheter. From the first the 
urine had a most disagreeable and strong acrimonious smell; 
occasionally it was turbid, always viscid, and when allowed 
to stand in a glass a considerable sediment was deposited. 
It was now the 24th of August, and it was quite evident the 
disease was telling upon the constitution ; in fact, the animal 
was sinking. I therefore seriously reflected upon the me¬ 
chanical resources hinted at by Professor Varnell; and whilst 
the catheter was in the bladder, I connected to it the 
stomach-pump, and injected a quantity of warm water into 
the urinary cyst, then let it run back, again injected, and 
again let it run back. But this did not answer the 
purpose, for the water I injected only passed upon and 
over the sediment in the bladder, and ran off again from 
it without having been mixed with it. It then struck me 
that if I had my patient on his back, and my hand up 
the rectum, the sediment in the bladder would thus be 
turned upside down, and I could then inject large quan¬ 
tities of water into the bladder, and by gentle agitation 
with my hand, commix the sediment and the water, 
and then let it pass out through the catheter. I, therefore, 
had my patient at once placed upon his back. Mr. Lawson, 
jun., who had taken great interest in the case, was present, 
and kindly lent me his assistance. On introducing my hand, 
I now for the first time (it having hung pendulous and out 
of reach previously) felt a considerable quantity of soft sabu¬ 
lous matter, and judged it, whilst balancing it in my hand, at 
arm’s length, to be several pounds’ weight. I now pumped a 
good quantity of warm water into the bladder, and gently com¬ 
mixed it as indicated above; but in attempting to get it to 
run back again, two difficulties presented themselves,—the 
first was, the fluid would have to run up hill through the 
catheter and sheath, whilst the horse lay upon his back. I 
overcame this difficulty by having him turned upon his side;
