206 W. G. Mixter—Amylidenamine Silver Nitrate. 
account of some decomposition which occurs during the evapo- 
ration. The compound dissolves with but partial separation 
of silver in boiling water. The clear aqueous solution evapo- 
rated on a water bath leaves a slight black residue and a very 
soluble crystalline mass, which contains silver, reacts for am- 
monia and gives red fumes when heated with oil of vitriol. By 
distilling with ammonia water crystals are obtained in the distil- 
late which reduce silver. Hot dilute acids decompose it with 
the separation of an oil which has the odor of valeral, and hot 
oil of vitriol evolves nitrous fumes from it. The reactions 
show that the substance contains the amyliden, ammonio and 
nitro groups and that it is an amine analogous to Rose’s

The name amylidenamine silver nitrate is perhaps the best 
that can be given to the substance until more is known of its 
constitution. If the corresponding ammonio compound be 
gentammonium nitrate (Graham— 
Otto, iti, 840) the derivative from valeralammonia may be 
arded as di-amylid i tamylid ium
