The author proved by observing long tubes of dilute suspensions of silica and mastic in water that brown tints may thus easily arise, but he obtained green tints only from colloidal suspensions of alumina and silica. The diffraction of light in such suspensions and not the nature of the suspended particles is therefore the cause, under certain circumstances at any rate, of the green tint of natural waters.

Glycol and Glycerol, if diluted slightly with water, lost their brown tint on filtration through animal charcoal and showed a blue color when observed through a long tube. The color was deeper than that of water or ethyl alcohol, indicating that the depth of color bears a relation to the number of hydroxyl groups present.
