The behaviour of the iodides of ethyl and amyl in contact with zinc*, led me to 
expect that the gaseous products of the decomposition of iodide of methyl by the 
same metal would consist of methyl, hydride of methyl, and the first member of the 
olefiant gas series, methylene ; but in addition to the proof of the absence of this latter 
body afforded by the absence of all absorption by fuming sulphuric acid, analyses 
Nos. II. and III. demonstrate the impossibility of methylene being a constituent of 
the gaseous mixture ; for on constructing three equations in which the volumes of
