DISEASES OF THE URINARY ORGANS. I19 



the case, but there is no doubt that the urine was highly 

 charged with phosphatic matter, and, it may be, rendered 

 alkaline, probably from mal-assimilation ; and, in such a state 

 of the fluid the phosphate cannot, be maintained in solution. 



" Our limited literature on this subject does not permit us 

 to refer to many instances of calculus, in the urinary organs 

 of the dog ; but tvyo cases occur to us, both possessing some 

 points of interest. One instance of vesicular calculus is re- 

 corded by the late Professqf Morton in his pamphlet on 

 'Calculous Concretions.' The. animal affected with the dis- 

 ease was a very small spaniel ; the calculus was so large as 

 to nearly fill the bladder, and was felt easily through the 

 walls of the abdomen. The next case was one. of renal cal- 

 culi,* forwarded to us by Mr. Clarke, of Islington. No his- 

 tory of the case was given, but the morbid specimen is in 

 itself of: coi^siderable interest. In both kidneys there are 

 several small calculi, the largest is of the. size of a horse- 

 bean, and is lodged in the pelvic cavities. In composition, 

 all these concretions from the several dogs are closely, 

 allied:" 



" RETENTION OF. URINE ASSOCIATED WITH CALCUH IN THE 

 BLADDER OF A. BITCH OF THE KING CHARLES BREED, AGED 

 TEN, YEARS. 



"By Messrs. Gowing and i'oi, M.R.C.V.S., Camden Town. 



" The bitch was observed to be dull and off her appetite 

 for the last three or four days. Some time previously she 

 had tried to urinate, passing a drop or two occasiotially, but 

 no effort could produce a full stream, and lately it was re- 

 ported that her endeavors were futile, none being passed. 

 Upon examination of the parietes of the abdomen the bladder 

 was found to be distended. Accordingly an attempt was 

 made to pass a catheter, but without success. The animal
