and set aside. In the course of a few hours the salt was depo- 

 sited in orange-red tabular crystals of remarkable beauty, and 

 often of considerable size. It" is readily soluble in cold "water, 

 and still more so in hot, and is deposited unchanged from its 

 solution. It possesses considerable stability, but by long-con- 

 tinued boiling it undergoes decomposition. Its analysis gave, —

Aurochhnde of A^thylopicoline. — This compound is readily 

 formed by adding a solution of chloride of gold to the nitrate, with 

 excess of hydrochloric acid, obtained from the iodide, in the man- 

 ner employed for the production of the platinum salt. It is slowly 

 deposited in the form of golden-yellow flattened prisms of great 

 beauty. It is sparingly soluble in cold water, readily in hot, 

 and is deposited unchanged on cooling. It is insoluble in 

 alcohol and jethcr. Ammonia converts it into a cinnamon-brown 

 powder, and it is instantly blackened on the addition of potash 

 to its hot solution. The specimen analysed was dried at 212°, 

 and burnt with chromate of lead.
