Roux's treatise on photomicrography, illustrated by 11 photomicrographs, with one additional photomicrograph in a composite alongside 3 images of cultures. Plates V and VI on Rouget du porc, are probably the first published images of the E. rhusiopathiae bacillus affecting swine, isolated by Pasteur and Thuillier in 1882. They also may be among the photomicrographs that Roux presented to the Société de biologie in 1885 and described in a paper titled, Présentation de photographies du microbe du rouget du porc, published without the images in the records of the society (Comptes rendus, vol. 37, p. 681).
There are also 2 in-text phototypes of the apparatus he used to capture his images of microscopic organisms. Fitted behind the stage mount is a magnesium ball and oxy-hydrogen jet lantern that Roux invented, subsequently publicized by a number of journals including that of the Royal Microscopical Society (vide: 1890, Pt 1, p. 241). As director of services under Duclaux at the powerful l'Institut Pasteur, Roux had the funds to fabricate or purchase the most technologically advanced instruments for his research. Roux assumed Duclaux's position as general director of the Institut in 1904.
