DISEASES OF THE BLADDER, ETC. 



The following may be taken as an average analysis of the 



various calculi : — 



Horse. 

 Carbonate of lime, . • • 85-03 



Carbonate of magnesia, 

 Phosphate of lime, 

 Organic matter, . 

 "Water and loss, ,

In addition to these constituents, the oxalate of lime, silicic 

 acid, and iron are occasionally found. 



Ox {Filrstenherg), 

 Carbonate of lime. 

 Carbonate of magnesia, .

Sheep (Furstenherg). 

 Carbonate of lime. 

 Phosphate of hme,

The foregoing analyses of Flirstenberg have very clearly 

 sliown that the calculi of sheep differ from those of the horse 

 and ox, in containing the ammonio-magnesian phosphate. It 

 would be interesting — would space permit — to inquire into this
