Show Abstract
Four different methods of microscope observation of the phosphorescence of minute structures in cells or cell products, or microcrystals, both organic and inorganic, are described. The material must be dry or nearly so and the illumination short ultraviolet such as occurs in condenser discharges in air or in mercury, or the iron arc. Observations on various types of material, including tooth sections, are described. Some protein particles, notably casein, must be rayed a short time before they become markedly phosphorescent and they lose this property quickly on standing in the dark.
