The specific gravity of the bithiosulphocyanide of amylen is 1:16. Like the 
preceding compound, it is also a liquid. 
These bodies are perhaps chiefly interesting as showing how many halogens 
may be introduced to an olefine, provided they be offered in a systematic manner. 
Looking at these manifold substitutions of chlorine in the bisulphochloride of 
amylen there seems to be no reason why oxygen acids should not be also intro- 
duced in place of the chlorine; that is, why such bodies as

should not be formed, which would be the analogue of acetic ether. 
The alcoholic nature of the hydrated bisulphoxide of amylen appears to be 
further evinced by its forming a copulated acid when dropped into a large excess 
of sulphuric acid, which is kept quite cold.

The behaviour of the bisulphide of chlorine towards the olefines of the form

and the varied transformations which we have seen presented by the com- 
pound resulting from the union of bisulphide of chlorine with amylen, lend addi- 
tional interest to the formation and properties of the bisulphide and bichloride of 
amylen,

As neither of these bodies has been described, a short account of their pre- 
paration will not be out of place here. 
If an alcoholic solution of the bisulphochloride of amylen be treated with zine 
and sulphuric acid, the whole of the chlorine is removed, as chloride of zinc and 
hydrochloric acid, after a few hours’ digestion on a water bath. The reduction, 
however, does not stop at this point; sulphuretted hydrogen is evolved. The 
organic compound, however, under all the conditions I have employed, refuses to 
part with the whole of its sulphur, the result being a product which, after puri- 
fication from the alcohol by evaporation and washing with water, is indeed rich
