(1) From this series of experiments carried out under good optical conditions, in one case as good as present lenses allow, we conclude that capillary contraction occurs in the rabbit's ear‐chamber, that this contraction is under the control of the sympathetic nervous system, and that endothelial swelling causes the obliteration of the vessels. No positive evidence was obtained of the participation of Rouget cells in this contraction. (2) “Spikes” on the endothelium of slightly injured veins have been noted. Red corpuscles hang on these, often for several seconds. The chambers have been made in the laboratory by Mr. S. W. Bush, to whose skill we are greatly indebted. Mr. J. Kent has had charge of the animals. The drawing is by Mr. H. Axtell.
