The behaviour of a suspension of carbon particles injected intravenously was observed in inflamed and non‐inflamed blood vessels of the web of the frog (Hyla cœrulea) . Carbon deposits occurred in a discontinuous network roughly outlining endothelial cells in some inflamed vessels. The distribution was similar to stomata and stigmata demonstrated by silver nitrate. Intercellular cement was not observed despite increased capillary permeability and the only circulating translucent material to which carbon adhered, appeared to be cellular constituents of the blood. The experiments failed to support the contention that a sticky intercellular “cement” substance exists.
