CHRONIC DISEASE OF THE BLADDER.

thoracic viscera appeared to have been healthy. The 
pericardial sac contained about a pint of fluid. A few 
hours before the death of the horse, I had noticed an inter- 
mittencv of the pulse to exist. On exposing the spinal 
cord, from the brain to its extremity, the membranes cover¬ 
ing it were found to be distended with fluid; and on dividing 
them, a quantity of clear serum—I should say about five or 
six ounces—trickled away in a stream. 
When I first saw the case the pulse was strong, and num¬ 
bered sixty in the minute. From the commencement I 
thought the case a hopeless one, inasmuch as the disease 
having been allowed to go on uncontrolled for forty-eight 
hours, effusion to a considerable extent had doubtlessly taken 
place. 
The symptoms in this case appeared to me to be rather 
peculiar. Those cases of paralysis that have previously 
come under my notice have been generally traceable to some 
known cause, as strains in leaping, pulling heavy loads, &c.; 
The pulsations of the heart not having been materially 
increased in force or in frequency ; nor did the animals give 
evidence of much pain: pure and simple paralysis being 
alone present. 
In this case, the disease was traceable to no known cause. 
It was apparently an idiopathic affection. At first the para¬ 
lysis was confined to the right hind-quarter ; but there was a 
convulsive twitching of all the other voluntary muscles. The 
animal was frequently making the most strenuous efforts to 
rise, until the inflammation had extended along the whole 
course of the membranes; and even then, although the effu¬ 
sion was so great, and the paralysis so general, the horse was 
evidently suffering great pain. 
CHRONIC DISEASE OF THE BLADDER OF A 
COW. 
By W. D. Bray, Y.S., Ulverston. 
I have forwarded to you, per rail, an abnormal specimen 
of the bladder, together with the uterus of a cow. 
My attention not being called to the case until after the 
animal had been slaughtered, I am not able to furnish you 
with a complete history of the case. 
The subject was a half-bred short-horn heifer, two years
