326 This identical phenomenon was the basis of Quinckeãs theory of amoeboid movement (Ueber periodische Ausbreitung von Flû¥sôÙsigôÙkeitsoôÙberôÙflûÊchen, etc., SB. Berlin. Akad. 1888, pp. 791ã806; cf. Pflû¥gerãs Archiv, 1879, p. 136).

330 We may trace the first steps in the study of this phenomenon to Melsens, who found that thin films of white of egg become firm and insoluble (Sur les modifications apportûˋes û lãalbumineã...ãpar lãaction purement mûˋcanique, C. R. Acad. Sci. XXXIII, p. 247, 1851); and Harting made similar observations about the same time. Ramsden has investigated the same subject, and also the more general phenomenon of the formation of albuminoid and fatty membranes by adsorption: cf. Koagulierung der EiweisskûÑrper auf mechanischer Wege, Arch. f. Anat. u. Phys. (Phys. Abth.) 1894, p. 517; Abscheidung fester KûÑrper in OberflûÊchenschichten Z. f. phys. Chem. XLVII, p. 341, 1902; Proc. R. S. LXXII, p. 156, 1904. For a general review of the whole subject see H. Zangger, Ueber Membranen und Membranfunktionen, in Asher-Spiroãs Ergebnisse der Physiologie, VII, pp. 99ã160, 1908.
