DE. E. FEANKLAND’S EESEAECHES ON OEGANO-]VIETALLIC BODIES. 
is a light straw-coloured, somewhat oily liquid, which does not solidif)’ on exposure to 
a cold of — 13° C., and possesses an extremely pungent and intolerable odour, resembling 
oil of mustard ; the inhalation even of a very minute amount of its vapom bemg h^ y 
irritating to the respiratory organs. Its specific gravity at lo C. is 2-0.3.9. At -08 . 
it enters into ebullition, but cannot be distilled without decomposition ; the thermometer 
rapidly rises, and at 230° C. a copious deposition of iodide of tin takes place. It would 
be interesting to study the action of zincethyl upon this body. 
Stannic ethylomethide is more readily acted upon by aqueous hydrochlonc acid than 
the corresponding ethyl compound ; a copious evolution of gas takes place, and a crA'sta - 
lizable salt is formed. Submitted to analysis, the gas yielded the foUo^g results : 
I. It did not contain any gases absorbable by anhydrous sulphuric acid. 
II. Treated with an equal volume of alcohol it was partially absorbed

The two combustions, a and h, which were made with portions of gas collected in two 
different operations, show the gas to be a mixture of the hydrides of ethyl and methyl; 
and this result is confirmed by determination No. II.,—hydride of ethyl being solub e m 
alcohol, whilst hydride of methyl is insoluble. The results of analyses Nos. II. and II .
