The detanaiianon of silicium and chlorine was made by de- 
composing the body in a flask with an alcoholic solution of am- 
monia, distilling the alcohol and heating the flask in order to 
etermined in the filtrate from the silica. The alcohol carries 
Over with it on distillation a little NH,Cl, and it must be care- 
fully condensed and evaporated slowly and the residue added to 
the filtrate from the silica. 
he monochlorhydrine of silicic ether is a sp li fre 
which does not fume in the air, rapidly dec 
moisture or by water with evolution of HCl. It ean 
on alcohol; HCl is given off and normal silicic ether is fo 
t burns with a green flame due to chlorine and with a "pioke 
acid.
