Absorption of Iodine by Solid Substances. M. GUICI-I:',RDo

(Comptes rendus, cli, 236.)--Silica , both natural and calcined; alumina, calcined at 6oo°C.; magnesia, calcined at IO25°C.; and glucina all absorb iodine in quantities inversely proportionate to the degree of calcination. The differences in absorption are due to the shrinkages of the interspaces between the particles, and the cessation of absorption probably marks the disappearance of these interspaces and corresponds with the maximum density of the substance.
