base, Darcet 16-04 acid + 20-85 base, and Klaproth 16 acid + 

 22 base. These analyses very nearlv coincide with my statement. 

 - * This supposes the salt a compound of 100 acid + 35-169 base. 

 Now Schrader found it a compound of 100 acid + 33-92 base, and 

 Berthollet of 100 acid + 36-36 base. 



^ This approaches the analysis of Bergman, but does not coin- 

 cide. The existence of the salt called carbonate of ammonia in the 

 table has not been ascertained. 



2 This supposes the salt composed of 43-18 acid + 56 82 base. 

 Now Dr. Marcet obtained 43-9 acid + 56-1 base. 



** This supposes the salt a compound of 22-04 acid + 77*9S 

 base. Now Kirwan obtained 22 acid + 7^ base, and Berzelius 

 21-6 acid + 78-4 base. 



' According to this statement the salt is a compound of 28-505 

 acid + 71'495 base. Now Klaproth's analysis gives us 30 acid + 

 69'5 base. 



•^ This supposes the salt composed of 69-911 acid + 30-089 

 base. Now Kirwan and Fourcroy found it composed of 66-6 acid 

 + 33-3 base. 



' This supposes it a compound of 34 acid + 29'2 base. But no 

 such compound is known. The carbonated magnesia of commerce 

 approaches most nearly to a compound of 1 c + 2 w. 



"• This corresponds exactly with Klaproth's analysis, but no 

 stress can be put upon it, because it was from that analysis that the 

 number for yttria in my first table was derived. 



" We have no analysis of this salt. Vauquelin found it a com- 

 pound of 55-5 zirconia + 44-5 acid and water. The numbers in 

 the table suppose it composed of 26995 acid + 55-5 base. It 

 would be correct if Vauquelin's carbonate contained 17'5'05 per 

 cent, of water. 



" This supposes carbonate of silver a compound of 16-806 acid
