268 On the Gaseous Combinations of 
(4.) Sulphuric ether dissolved it with great rapidity, and 
the solution was colourless. 
(5.) It did not dissolve in oil of turpentine, but con- 
tinued in smail globules, which attached themselves to the 
bottom of the vessel. 
(6.) It dissolved immediately in nitric acid, without ef- 
fervescence, or any apparent change in the liquid. 
(7.) When dropped into sulphuric acid, a copious effer- 
vescence took place, the smell of oxymuriatic acid became 
evident, aud the liquid remained clear. 
(8.) When left in an open vessel, it eyaporated com- 
pletely, leaving only a green trace, 
From these properties it is obvious that the liquid in 
question does not belong to the class of oils. It is a sub- 
Stance of a nature quite peculiar, and seems to consist of 
the two gases simply combined together. It has consider- 
able resemblance, at least in taste, to the pyro-acetic spirit 
of Mr, Chenevix. 
4. When olefiant gas is mixed with thrice its bulk of 
oxygen gas, it dctonates very loudly, when an electric spark 
is passed through it, and burns with a strong white flame. 
According to Mr. Dalton, it consumes exactly thrice its 
bulk of oxygen gas, and forms twice its bulk of carbonic 
acid. My experiments, as will appear from the following 
table, very nearly coincide with his. The gas used contained 
16 per cent, of common air, and the oxygen gas was mixed 
with 11 per cent, of azote,
