of methyl, but have no doubt that, by collecting the gas as evolved from the decom- 
position-tube over mercury, and absorbing the zincmethylium vapour by dry iodine, 
the methyl would be left in a state of purity. It perfectly resembles in its properties, 
chemical and physical, the methyl procured by Kolbe from the electrolysis of acetic- 
acid *. 
Examination of the Gas (3. 
This gas, evolved by the action of water upon the solid and liquid products of the 
decomposition of iodide of methyl by zinc, proved, as might have been anticipated, 
to be pure hydride of methyl, derived from the decomposition of the zincmethylium 
with which the crystalline residue of iodide of zinc was saturated. Its eudiometrical 
analysis yielded the following results : —
