A detailed investigation of the Raman bands for water in the solid and liquid states was first made by the author. Therein it was found that both ice and water give three sets of bands at λλ 4170, 4680 and 5105 A. U. respectively, corresponding to exciting mercury lines at λλ 3650, 4047 and 4358 A. U. The positions of these bands were not identical for ice and water. The former was found to give sharper bands and their shift form the original exciting line was less than for water. The mean infra-red absorptions corresponding to the bands for ice and water were 3·1 μ and 2·99 μ respectively. The above work was done with an instrument of very small dispersion, so that the structure of the band in either case could not be studied at all.
