As the gas^ left unabsorbed by fuming sulphuric acid, was 

 soluble in about its own volume of alcohol, with the exception 

 of a very small per-centage due to the nitrogen introduced by 

 diffusion through the sulphuretted water, it could not contain 

 either hydrogen or hydride of methyle ; and the result of the 

 above combustion proves that it is hydride of sethyle, for I have 

 shown that 1 vol. of hydride of sethyle consumes 3-5 vols, oxygen, 

 and generates 2 vols, carbonic acid, numbers which almost exactly 

 correspond with those obtained. 



17*48 vols, of the gas, containing 17*15 vols, of combustible 

 gas and '33 vol. of nitrogen, consumed 59*93 vols, oxygen and 

 generated 34*63 vols, carbonic acid; hence 



Further, the gas agrees in all its chemical and physical pro- 

 perties, with the hydride of sethyle prepared by the action of zinc 

 upon iodide of sethyle in presence of water. 



The composition of the gas absorbed by fuming sulphuric acid 

 was determined by exploding a known volume of the original 

 gas with excess of oxygen, and determining the quantities of 

 oxygen consumed, and carbonic acid generated. 



This determination gave the following numbers : —
