204 Mr. G. Gore on the Properties of [May 4, 



mitted to analysis this salt exhibited the composition required by the 

 formula 







lOAg. 



Diethacetate of silver differs from the silver salt of the caproic acid pre- 

 pared from cyanide of amyl, by its much greater solubility in water, and 

 by its ramiform crystallization, amylic caproate of silver crystallizing in 

 large and very thin plates, which are nearly insoluble in cold water. 



In conclusion, there can be no doubt that this reaction is capable of a 

 very wide extension, and that, by its means, we shall be able to ascend 

 many of the well-recognized homologous series. Whilst pursuing it in the 

 acetic and benzoic series of ethereal salts, we also purpose to extend it to 

 the alcohols and ethers.
