ON SOME DERIVATIVES FROM THE OLEFINES. 613 
The bodies C1S, and SCI unite directly with the olefines C, H, and C,, Hi, 
to form 
* (1) C,H, 8, Cl, — Bichlorosulphide of ethylen. 
eee RO, 2 .ChiSe Bisulphochloride of ethylen. 
* (8) C,, H,, 8, Cl, Bichlorosulphide of amylen. 
* (4) C,, H,, C18, Bisulphochloride of amylen. 
At elevated temperatures, C, H, acts upon 8, Cl to produce 
(5) C,H, 8, Cl,  Bisulphochloride of chlorethylen.

“On sait que 2 atomes d’oxyde d’ethyléne peuvent se réunir pour se combiner a 1 atom d’eau. 
Tl n’est pas done extraordinaire que 2 atomes de sulphure d’amyléne de reunissent pour se com- 
biner a 2 atomes de chlore, Si cette maniére de voir est exacte on doit representer la constitution

With regard to the first portion of M. Wurtz’s remark relative to the bichlorosulphides, I have 
to observe that the body SCl, has not been shown to exist, and, therefore, how its atomicity would 
be affected by a withdrawal of chlorine is a premature speculation. 
Further, if the diatomic olefines are combined with two atoms of sulphur (‘corresponding to the 
oxides”), why do they combine with two more atoms of halogen? Not, I think, because they have 
two stages of saturation, as M. Wurrz’s view would indicate, but because halogen groups may have 
the same index of saturation as simple halogens. In this manner

Concerning the bisulphochlorides, there is perhaps as much reason for doubling their formule as 
for doubling that of water; and so for the bisulphoxide.

I cannot interpret, unless it belong to the class of “ mixed types.” 
On the other hand, we may regard it as 
S, 
Cy Ears HO, 
which, I insist, is more congenial to analogy. 
But, in truth, if the function of a formula be to express potential recomposition, these bodies 
eminently show the insufficiency of a single formula.
