Mr. Griffin on the Constitution of 



Table XII. — Carbonate of Potash. 

 KO J) C0 2 = 886-354 grs. Temperature 62° F. 



Observations on the Table of Carbonate of Potash. 



The strongest solution of carbonate of potash that can be 

 formed at 62° F. has a specific gravity of 1-5739 and a che- 

 mical strength of 665°. Its formula is KO, CO 2 + 7H 2 0. 

 The greatest amount of condensation occurs in this first solu- 

 tion, where the measure of the test atom of carbonate of 

 potash decreases at once from 54*66 septems to 37'46 septems, 

 effecting a condensation of 17'20 septems. In a solution of
