    looked downward; a rubber cork perforated by a glass tube was securely fastened to the top of the cyl- inder, and the tube was connected with an apparatus designed to exert any atmospheric pressure required. Pressure sufficient to raise a column of mercury twen- ty-eight millimetres was continued for an hour and a half, the skin being pressed out with great force in dome shape at the bottom of the cylinder, which was kept during the time in blood-warm water. The specimen was then placed in alcohol. It was observed that the injection mass had gone, at one or two points to the surface, and on making vertical sections of the skin the next day the cutis was found to be penetrated by the mass in vertical blue lines, which united at various intervals by horizontal branches, occasionally so numerous as to present an alm’ost continuous blue surface. The subcutaneous areolar tissue was uni- formly colored blue. (Figure 6.) Opinions on the character and distribution of the lymphatics of the skin seem to differ. For instance, Neumann describes them as vessels distributed throueh the skin in two horizontal layers, a superficial and a deep one, the vertical connection between the two being found only at comparatively rare intervals.^ Renaut regards the skin as a lymphatic sponge, the minutest ramifications being but tbe spaces between the bundles of fibres, the coarser differing from these in having an endothelial lining (connective-tissue cell ?), there being in neither case a true wall, which is found only in the lymphatic vessels of the subcutaneous tissue.^ Vertical 1 Zur Kenntniss der Lymphgefasse der Haut, von Isidor Neu- mann. ^ Renaut, op cit.
