PREPUCIAL CALCULI. 
One of our correspondents, Mr. Trumbower, sends us a speci¬ 
men of a very large prepucial calculus, and gives in his letter, 
which will be found in the pages of this number of the Review, 
the history of the case. 
These concretions, which are found in the sheath of the horse 
and pig, exist also in the ox and sheep, and are concreted around 
the hairs surmounting the prepuce. They consist of masses of 
phosphate ammoniaco-magnesian, oxalate, and carbonate of lime, 
mixed with organic matter of a very offensive and peculiar odor. 
The specimen, which we have received, is the largest which was 
ever brought to our consideration, and in connection with the pre¬ 
vailing existence of those concretions and the nature of the water 
drank by the animals thus affected, we would suggest the 
propriety of a minute examination of the condition of the urinary 
apparatus, looking for urinary calculi in the bladder, or the 
urethra, as there might be found the starting cause of these accu¬ 
mulations.
