Silicon with Alcoholic Radicals. 819 
III. This analysis was made from a liquid whose boiling-point was 
180°—185°, but which had been distilled a larger number of 
tumes than the last. 
Substance=0°2540 grms. CO,=0°4750 grms.; H,O=0°2482 grms. 
The following analyses were made of products belonging to 
the same series of distillations as the first. 
IV. Boiling-point=190°-200°.  Substance=0°2585 grms.; CO, 
‘4785 grms. ; H,O=0°2280 grms. 
V. Same substance=0°3135 grms. ; Ag Cl=0°3238 grms. 
VIL. Another product boiling at 190°-200°. Substance=0°2345 
grms. CO,=0°4400 grms. ; H,O=0°2145. 
The composition of all these products approaches that of 
monochlorated silicic ethyd.

Corresponding results were obtained in the analysis of several 
other products distilling at about the same temperature.
