ON SOME DERIVATIVES FROM THE OLEFINES. 615 
Comparing this analysis with the one given of the entire substance, ‘Quarterly 
Journal of Chemical Society,” we find—

Which proves that the substance is single. The bisulphochloride of amylen, on 
being treated in a similar manner, gave a substance which showed the following 
composition :— 
I, 0:3934 grms. gave 23°81 per cent. sulphur. > 
II. 0.2677 grms. gave 25°66 per cent. chlorine.

I considered a determination of the carbon unnecessary. 
Having thus established the right of these bodies to be considered pure and 
homogeneous, the next thing was to examine the action of chlorine upon the 
bisulphochloride of ethylen. 
If dry chlorine be made to act upon bisulphochloride of ethylen in the dark, 
hydrochloric acid is evolved, together with chloride of sulphur: the temperature 
rises considerably. If the action be assisted by the heat of a water bath, and the 
excess of chlorine be expelled by a current of dry carbonic acid, a product is 
obtained which is identical with that got by the action of chlorine either upon 
the bisulphochloride of clorethylen C, Gi Cl S,, or upon the bisulphide of ethy1.* 
For on analysis, 
I. 0°3824 grms. gave 70°69 per cent. of chlorine. 
II. 0:4880 grms. gave 10°63 per cent. of sulphur.
