Meldola, R. (October 1874). "Recent Researches in Photography" . Popular Science Monthly. Vol. 5. pp. 717–720. ISSN 0161-7370, copying from Nature. After summarizing the discoveries of Vogel and Edmond Becquerel, this article notes some of the prospective benefits to science and to photography in general. Caution: an error found in early English-language reports of Becquerel's results with chlorophyll is repeated here. In his original paper in French (Comptes Rendus (1874) 79:185-190) Becquerel reports strong action between Fraunhofer lines C and B (red), not C and D (orange) as it appears in a widely-copied English translation which is reflected here. Subsequent references to these lines in his paper confirm that "C et B" as it appears on page 188 of the original is correct.
