428 MK. G. B. BUCKTON ON THE ISOLATION OE THE OBGANO-MIALS, 
Although expeviment gives too large a proportion of both carbon and hyclrogen for 
the ascribed formula:, the salt still less accords with chloride of stanethyl, from w i 
also the crystals differ, both in form and a sort of fatty . 
From the circumstance that no steady boiling-pomt could be obtamed fi-om that po 
tion of the distillate which came over below 210»C., and which reftised to « 7 sfr>Uize « 
appeared to be no pure chemical compound, but simply a mixture of an oily bodi and 
til salt last analysed. This belief was confirmed by noticmg its deportment towai s 
aqueous potash, which precipitated a considerable quantity of white oxide of stane y . 
Se solnL, on the other hand, with hydrochloric acid liberated the above-mentioned 
odorous oil. To isolate this last, the whole was mixed m a mortar with rathei strong 
aqueous potash, and the magma washed in a funnel plugged with asbestos. The was - 
ing was continued with weak potash until the rinsings were nearly luodoiuus. 
The liquid was then distilled, a good condensing apparatus being attached At first 
white pungent fumes passed over with the aqueous vapour, and coUected m the recenei 
in the form of oily drops, possessed of great causticity and powerful basic propel es. 
This product, in fact, is the aqueous solution of the oxide of an ethylated base con ain- 
ing tin, from which definite compounds may be obtained with sulphimc, hydiochloiic. 
As the sulphate is but little soluble in water, it seemed well adapted for fixing the 
constituents of the base. A portion of the aqueous solution of the oxide w as there ore 
nearly neutralized with sulphuric acid, and heated to about 80“ C., when an opake 
colomless and crystalhne salt appeared, which was di'ied in vactio over sulphiuic acid, 
and analysed. ^ r, +
