CROOKES, William (1832-1919). "The mechanical action of light". 2 parts. In: Quarterly journal of science, new series 5, July 1875, pp. 337-352 (Part I); new series 6, April 1876, pp. 228-256 (Part II). London: Offices of the Quarterly Journal of Science; Paris: Friedrich Klincksieck; Berlin: A. Asher, 1875-1876.
8o (214 x 138 mm). Text diagrams. Contemporary half green morocco, gilt-ruled, gilt-lettered spines, marbled boards (joints starting (Part I); joints split (Part II), extremities worn). Provenance: Newberry Library, Chicago (shelfmark label, withdrawal label on front pastedown; stamp on title).
FIRST EDITIONS, journal issue. The observations that led to Crookes' "light mill" or radiometer. Crooke erroneously thought that differences in a vacuum balance occasioned by different temperatures of specimens were caused by a link between heat and gravitation. Further investigation showed that light produced the same results, and Crookes attributed this to "light pressure", a theory proposed by both the corpuscular theory of light and by Maxwell in his electromagnetic theory. The movements were in reality the result of internal movements of molecules in the residual gas. Dibner Heralds of Science 160 (offprints); Norman 535. (2)
