MOLECULAR CONSTITUTION OF THE ORGANIC BASES. 
381 
Methylamylophenylamine is an oil of an odour similar to that of amylaniline ; it is 
almost insoluble in water : I have not prepared enough of this compound to deter- 
mine the boiling-point, which at all events is very high. It forms a crystalline plati- 
num-salt, whose analysis was sufficient to establish its composition.

The paragraphs now following are devoted to a brief account of several bases be- 
longing to the methyl- and amyl-series. 
Bases of the Methyl-series. 
The experiments described under this head were originally undertaken by my friend 
Captain Reynolds, who by many occupations unfortunately was prevented from 
continuing the investigation, so that I am obliged to take alone the responsibility of 
the following statements. 
Action of Ammonia upon Iodide of Methyl. 
If iodide of methyl be treated with a concentrated aqueous solution of ammonia, 
the former is rapidly dissolved, the completion of the reaction being indicated by the 
liquid assuming a yellowish tint. On opening the boiler-tube the liquid is found to 
be strongly acid, and to contain not less than five different iodides, namely—
