Numerous studies have been reported on the permeability of the wall of blood vessels. Among these studies, the recent work which was reported by Majno and Palade (1961) was of particular interest. Physiologist, such as Huduck and Mc Master have experimentally demonstrated that some pigments which do not penetrate the wall of blood vessels under physiological condition are able to penetrate the wall of blood vessels when chemical or electrical stimulations are applied to animals. This indicates that the permeability of the wall of blood vessels can be altered under experimental conditions. Tracing the flow of substances which have moved out of blood vessels should be of interest. In the present experiment, morphological studies on the processes of movement of Indian Ink and HgS were made according to the method reported by Majno and Palade (1961).
