awa}' from this soluble mass. It seems to be quite in- 

 soluble in hydrochloric acid thoug-h easih' dissolved b}^ 

 water. Anal^'sis shows that this mass is ^rOCl2 and 

 with it was found as an impurity whatever silica the 

 separation by heating- failed to remove. 



Lasth% my assistant. Dr. Baskerville. has shown 

 that much time and hydrochloric acid will be saved if 

 in the solution containing much iron the zirconium h}'- 

 droxide be first precipitated out by means of sulphur 

 dioxide. This precipitate can then be dissolved in acid 

 and purified b\' cr^'stallization as already- recommended. 



Of course it need scarcely be mentioned that if silica 

 has been removed by ignition and treatment with hydro- 

 fluoric acid, it will be necessary to fuse once more with 

 caustic alkali and repeat the ordinarv purification.

SOME ATTEMPTS AT THE FORMATION OF 

 ETHYL GLUCOSIDE. 



J. R. HARRIS. 



Glucosides are substances ocurring in nature in plants 

 and are supposed to be ethereal derivatives of the 

 g-lucoses. Under the action of dilute acids or ferments 

 they break up into g-lucose and other bodies. A num- 

 ber of these ethereal derivatives of glucose can be pre- 

 pared synthetically in the laboratorv. 



A. MichaeP obtained them by the action of alcoholic 

 solution of acetochlorh3'drose upon the alkali salts of 

 phenol.
