LARGE CALCULOUS MASS IN THE BLADDER OF A HORSE. 
By Mr. L. Soula. 
Deposits of a sedimentary nature are not uncommon in the 
bladders of solipeds, and a number of instances of their occur¬ 
rence are recorded b} 7 Hering, Verheyen, Lafosse and Zundel. 
The author, however, reports one of which the dimensions and 
weight are far above all those before on record, its weight being 
not less than 15 kilogrammes, or about 30 pounds. It was found 
at post-mortem of an animal which had been destroyed on ac¬ 
count of his age. The mass was of a light yellow color, with a 
strong odor of urine, irregularly ovoid in shape, slightly flattened 
from above, large on its anterior extremity, and ending in a 
blunt point at the posterior. It measured about 15 inches in 
length, 12 in width, and 20 in thickness. On its superior face it 
showed a depression, or kind of cavity, representing the entire 
dimensions of the urinary reservoir. The ureters opened into the 
bladder on its level. The analysis of the mass gave 105 parts of 
water, 188 of organic substances, 607 of carbonate of lime, 72 of 
phosphates, and 27 of ammoniacal salts and sundries.— Revue
