The determination which agrees least with the calculation is 
that of the hydrogen, which may easily be too great, as the crys- 
tals are decomposed under 100° C. ; 
Heated in the air the compound burns with the characteristic 
blue selenium flame. "It melts at 88°—90° C. toa clear, dark 
brown oil, (being probably partially decomposed.) solidifying on 
cooling to a dark apparently amorphous mass. Heated in a 
closed tube it melts and burns, part of the selenium being sub- 
limed as selenious acid, while another portion is reduced and re- 
mains behind in fused globules, drops of a yellow oil being also 
Ing faste; it gives no precipitate with bichlorid of platinum. 
Sulphurous acid reduces from its solutions a dark red fluid, ap- 
parently heavier and of thicker consistency than selenmethyl, 
(perhaps biselenmethyl). Hydriodic acid precipitates a dar 
black oil, an iodine substitution product, The chlorinated pro- 
duct dissolves easily in ammonia, forming a salt, crystallizing in 
of chlorid of silver. A solution of the salt is somewhat decom- 
Posed by heating, depositing a small quantity of silver. Owing 
fo the very small quantity of this salt which we had, we were 
unable to investigate further its properties. In the form of its 
crystals and alj its. physical properties, taste, odor, etc., it closely 
bles the silver salt described above (p. 249). eee
