VESICAL CALCULUS IN A MAKE.

stables nearly every animal was found affected, while in others, 
perhaps only next door, there would not be a single case. The 
outbreak is particularly characterized by great debility of the 
circulation, and as a consequence, marked oedema of the extremi¬ 
ties results. There is almost an entire absence of laryngeal and 
thoracic complication, and in but few instances are there dis¬ 
charges from the nostrils. The temperature rarely goes beyond 
105° F. The characteristics, suddenness of attack, extreme weak¬ 
ness, loss of appetite, etc., which belong to the disease, are 
of course present. 
I presume that under such circumstances purpura haemor- 
rhagica might be anticipated as a frequent sequel, but as yet I 
have seen only two cases. 
Cases of the disease respond more quickly to treatment than 
has been customary in the former epizootics which I have wit¬ 
nessed. General stimulants combined with heart tonics are all 
the remedies that seem to be required, owing to the absence of 
varied local complications. 
In the epizootic of last year, adenitis, laryngitis, bronchitis 
and pneumonia were quite common complications. 
Unlike the former visitations of this disease, there are many 
stables as yet not affected, and it would seem from present indi¬ 
cations, that they are likely to escape entirely. The weather is 
favorable, though, for its general prevalence. A majority of our 
days for the past two weeks have been cloudy, damp, often rainy, 
and the changes of temperature frequent and marked. 
I have seen no fatal cases. 
VESICAL CALCULUS IN A MARE. 
By R. D. Eaton. 
A brown mare, the property of Mr. Ira Vanguilder, was 
brought to my office suffering with great trouble of her urinary 
organs. On examination per vagina, I discovered in the bladder 
a large calculus which I thought was about the size of a goose 
egg. Doubting the possibility of successfully removing it, on
