246 On the Properties of Telluramyl and Selenmethyl. 
The estimated amount of tellurium however differs very widely 
from this. But if we reckon it from the loss we obtain 53:1 and 
53°5 per cent, numbers agreeing very closely with the formula. 
We can perhaps think that in this compound, only 3 of the tel- 
lurium is precipitated, when treated by the general method for the 
estimation of tellurium. We must further think that under such 
conditions, buty] CsH» together with C2H: is formed from amyl 
C:ioH1: which perhaps can occur from the action of the sulphu- 
ric acid upon the fusel oil in the preparation of sulphamylate of 
ime. Whatever this body may be it appears to be separat 
with the aid of heat into tellurium and the alcohol radical, depos- 
iting even when heated in an atmosphere of carbonic acid gas, 
metallic tellurium in beautiful crystals, and as this decomposition 
must have already begun during the original preparation, it is 
easy to see that the product must be mixture of different bodies. 
At any rate the body which is the chief constituent, is entirely 
analogous to tellurmethyl and tellurethyl in its reactions, being a 
radical combining with oxygen, chlorine, etc 
Telluramyl isa reddish yellow liquid heavier than water, of 
a disagreeable, though somewhat aromatic smell. A portion from 
the specimen analyzed boiled at 198° C. On exposure to the 
air it is oxydized, leaving a white residue: distilled in an atmos- 
phere of carbonic acid gas, it deposited a considerable portion of 
_finely crystallized tellurium. 
itrate.—By the action of nitric acid a yellowish white resin- 
ous substance is formed, of a pleasant etherial, aromatic odor, 
soluble in boiling water, from which a part is deposited in oily 
drops on cooling: by allowing the remaining solution to stan 
for several days, the nitrate crystallizes out in clear, transparent, 
colorless plates. The crystals heated in a closed tube melt and 
burn with a blue tellurium flame. It fuses at 40° C. : 
An analysis of the crystals gave 37-8 per cent. of tellurium ; 
had the compound been C1cH11TeO, NOs it would have given - 
32°56 percent. The formula C1cH1;TeO, HO + CicH1:TeO, 
NOs, corresponding to the formula of the sulphate and oxalate of 
tellurethyl*, gives 36-9 per cent. 
Chlorid.—Hydrochloric acid precipitates a clear, colorless, 
heavy oil, without odor, when added to a solution of the nitrate. 
Bromid.—Hydrobromic acid precipitates a clear, pale yellow, 
heavy oil, without odor. 5am 
Todid.—This is precipitated, on the addition of hydriodic acid 
or iodid of potassium, in yellow drops which collect togetber as 
a dark red oil, heavier than water. Boiled with alcohol it's 
changed into a pale yellow amorphous powder, without odor, 
which becomes vermillion red when treated with ammonia, and
