acid gas is passed into it, unless the solution is boiled. a 
water yields analogous results. If with the latter, instead of

of the salts of potash have also been noticed to possess the 
Same power, though to a less degree, and I find that the 
salts of soda stand midway in this respect between those of 
ammonia and of potash, and that even chlorid of calcium exerts 
ore apg solvent power upon recently precipitated carbonate 
or lime, Soe 
_This solvent action may be seen by treating the recently pre- 
cipitated carbonate with a great excess of a solution of a 
any alkaline salt, but is observed more distinctly in the great 
on boiling, if the alkaline chlorid be present in sufficient quan- 
to that of the alkaline chlorids, ot so far as I have observed, 
@ precipitate always forms on boiling. 
A splation of caiptels of ammonia or of sulphate of soda, 
When mixed with lime water exerts an influence almost pre- 
cisely like that of the alkaline chlorids, carbonate of lime not 
being precipitated even on boiling if they are present in suffi- 
Clent quantity. . 
4 solution of sulphate or of nitrate of potash behaves much 
lik on of sulphate of soda; but its influence is less strongly
