--Experiments on the electrolysis of solutions of dyes have shown that transport phenomena are well marked with those substances which form colloidal solutions but are absent in the case of dyes forming true solutions.
Simple Apparatus for Determining Melting Points. THEODOK \¥1*.yL. (Chem. Zeit., xxxiv, 488.)--A thermometer is slightly ex= panded just above the bulb. A glass ring loosely fitting the thermometer stem rests on the expansion ; it carries glass hooks placed vertically in pairs which serve to hold the melting point tubes in position close to the bulb. This obviates the use of india rubber rings or platinum wire for attaching the tubes to the thermometer.
