seales like those of naphthaline. Its constitution is represented by the 
formula B HO,, and its formation depends evidently on the substitu- 
tion of two atoms of hydrogen for two atoms of ethyl in the compound 
B CHO. This substance possesses an agreeable ethereal odor, and 
a very intense sweet taste. When exposed to the air, it volatilizes slowly 
at ordinary temperatures, and is partially decomposed, always leaving a

3. Vew propiat td on the Oxyd of Hthylene.—Wevntz has communi- 
cated some exceedingly ‘mitegn: and aan results of his continued 
Pg aie of the et hylene series. These may be briefly stated as 
follows: 1. Ox xyd of ethylene unites ainetly with acids and neutralizes 
them, hen the oxyd is heated in a water-bath with concentrated 
be oxyd unites iu like manner with anhydrous or hydrous 
acetic acid, and gives among other products the neutral acetate. 2. In 
uniting any acids the oxyd of ethylene is capable of forming basic salts, 
_ *us in the last experiment, after separating the neutral acetate by dis- 
popes there remains a considerable quantity of a liquid boiling above 
This oa three products which may be considered as basic ace- 
tates of oxyd of ethylene, and which constitute in reality the acetates of 
milan alcohols. The first boils at about 200°, and constitutes 
dieth tylen tate, which is Grain in consequence ‘of the following
