NEW SOLVENT FOR STONE IN THE BLADDER. 231 
sharp angular points and asperities of the broken fragments, 
where the practice of crushing is adopted. 
No apprehension need be entertained from the adminis- 
tration of injections if judiciously directed. Sir Benjamin 
Brodie found that the bladder bore without inconvenience a 
stream of fluid composed of two minims and a half of nitric 
acid for each ounce of distilled water. An Austrian sur- 
geon has recently introduced vinegar into the bladder, with 
excellent success, in an instance of phosphatic calculus. 
Mons. Lisfranc, the eminent French surgeon, has used in 
like manner tincture of cantharides for the cure of enuresis ; 
and I myself have thrown a dilute solution of nitrate of sil- 
ver into the bladder, with the best effect, in cases of chronic 
catarrh of that viscus. 
Nothing has hindered me from trying the carbonate of 
lithiabut its extreme scarcity. I would, therefore, suggest 
the importance of its preparation to the pharmaceutical che- 
mist. The mineral called spodumene, which is found at 
Killiney, near Dublin, contains, according to Stromeyer's 
analysis^ 5.6 per cent, of lithia.
