same view of the matter, I added, had been taken by Ernmert (‘ Beitrage zur Pathologie und Therapie,’ Heft I., s. 48, Bern, 1842). Here the question suggests itself; could Professor Virchow, in formulating his view that “ proliferation ” is the essential characteristic of incipient inflammation, have adopted Dr. Williams’s view, that the colourless corpuscles, seen accumulated within the vessels as just described, are actually new formations, and have taken them to be the manifestation of his “ proliferation ? ” § 30. In my ‘ Observations,’ in Ho. xxviii. of the ‘ British and Eoreign Medical Eeview,’ 1842, under the heading of “ Attractions and Eepulsions of the red and colourless cor- puscles,” it is remarked:—“Erom the facts stated in the preceding part of this paper, it may be admitted that the red corpuscles have an attraction for each other, but Ettle or none for the colourless corpuscles. The accumulation of the colourless corpuscles, at the inner surface of the vascular wall, was taken by Ascherson and Weber * to indicate the existence of some kind of attraction between them and these walls.” Again, in my Eeport on the “ Nature of Inflamma- tion,” in No. XXXIV., op. cit., I remarked : “ When the circu- lation in the web of the hind foot of a frog is attentively observed under the microscope, the colourless corpuscles of the blood are seen, if the stream be slow, to accumulate on the inner surface of the wall of the vessels—principally radicles of veins—along which they slide or roll over and over, whereas the red corpuscles, which occupy the axis of the stream, are carried directly onwards. Erom the differ- ences in the position, and in the mode and rapidity of progression exhibited in the case of these two kinds of blood- corpuscles, it appears that there is something of the nature of an attraction between the colourless corpuscles and the walls of the vessels, but an absence of attraction between tlie red corpuscles and these walls, as also between the red and colourless corpuscles themselves. Though the red corpuscles keep together in the axis of the stream, sliding on each other, there is not apparent among them any actual tendency to * Muller’s Archiv.
