    ever, was loose and it appeared as if the individual fibres had been pressed apart to form clefts of varyino- size (fig-. 5) ; while between the outer surface of many of the nerve bundles and the inner surface of the perineurium existed larg-e clear spaces, which surrounded the fasci- culi to a varying degree (fig. 5). These appearances were attributed to dilatation of the lymph spaces within the fterve stalk. The nerve bundles maintained for the most part their usual shape but were very evidently increased in size. This enlargement was due to an increase in the intrafascicular connective tissue (endoneurium), which formed a fine honey-combed fabric, the cells of which, as shown by Van Gieson and Pal-Weigert, were found to be entirely free from any nerve elements proper. The vessels in the newly formed tissue were comparatively few in number, possessed relatively thick walls, and exhibited a tendency to arrange themselves in clusters or groups. The vascular structures present, however, were engorged with blood as were also the vessels of the rest of the nerve ; and the tissues generally, outside the fasciculi, were infiltrated with large numbers of extravasated red blood cells.
