lene and for its compounds, which I assigned to them in my 
first communications to the French Academy of Sciences, when 
I was unacquainted with the density of vapor of the sulphid of 
ethylene.’ 
Oxyd of sulphid of ethylene—This body is the only product of 
oxydation of the sulphid of ethylene by nitric acid at a tem- 
perature not exceeding 100° C. It is best prepared by treating 
the sulphid with a small excess of fuming nitric acid, and then 
washing, once with a small quantity of water, and afterward 
with ordinary alcohol until the product is freed from acid. An 
analysis of the body prepared in this way and dried at 100°C, 
gave:

_ * Mr. Husemann, who obtained the sulphid of ethylene by another reaction, 8 
well as by the one with monosulphid of potassium, and was occupied with its study 
at the same time as myself, was the first to publish a determination of its d 
of vapor in a note in the Chem. Centralblatt (ises, . 497), which appeared a short 
tine after the publication of my note in the Comptes Rendus (vol. liv, p- 1277); 
aml he deduced from this determination the rational formula ( G28), and named 
4 ’ i 
the body sulphid of diethylene. Mr. Husemann also studied the product of ra 
stitution of chlorine in the oxyd of sulphid of ethylene (the compound 0180) as 
ie 
to determine directly its rational formula), and obtained the body (67H cIso 
crystalline form by the action of chlorine water on the sulphid of ethylene. 
fact, that this body is the first product of substitution of chlorine in the oxyd 
phid of ethylene, speaks rather against, than for, oubling of the k 
mula, C,H,SO, although it ean not be regarded as deciding the question, as Wo"
