nitric acid, and then adding alcohol and ether, which throws down 

 the new acid in small crystals. It is soluble in water, and by eva- 

 poration yields fine crystals. In alcohol and ether it is quite in- 

 soluble. It fuses at 401°, and dissolves readily in potash and soda. 

 The composition was found to be represented by the formula C^g H^ 

 NOg, differing from that of anthranUic acid by the elements of two 

 equivalents of carbonic acid. 



Its salts are all highly soluble in water, and are with difficulty 

 obtained in the crystalline form. Its silver salt can only be pre- 

 pared by digesting the acid with oxide of silver, as when a neutral 

 apophyllate is added to nitrate of silver a precipitate of a double 

 nitrate and apophyllate of silver is obtained, which explodes when 

 heated. 



When the solution containing alcohol and ether, from which the 

 apophyllic acid has been thrown down, is evaporated, and then dis- 

 tilled with potash, a volatile base is obtained, which possesses the 

 composition and properties of methylamine, and under certain cir- 

 cumstances ethylamine also appears to be formed.
