Paris, Mallet-Bachelier (for l' Académie des Sciences), 1857. 4to (28.3 x 22.6 cm). 4 pp. (pp. 913-916). Original printed wrappers.

First announcement of the "first demonstration of the connection between a specific fermentation and the activity of a specific microorganism" (Garrison and Morton), and "The birth of bacteriology based on the isolation of the organisms which cause milk to sour" (Horblit). This publication PRECEDES Pasteur's famous Mémoire sur la fermentation appelée lactique (1858). Louis Pasteur (1822-1895) was "A chemist by training and profession [who] in a career of intense and brilliant work, rose to eminence in the fields of immunology, medicine and public health. Biological chemistry and the food and silk industries owe him eternal gratitude" (Dibner). It is rare to see this publication, especially in its original wrappers, uncut, and without any library marking. We offer the complete issue 45(22) (30 November 1857; pp. 909-940) of the Comptes Rendus des Séances de l'Académie des Sciences. Wrappers ever so slightly faded at edges (as often with pink wrappers), and a bit frayed and chipped, as usual with uncut wrappers; otherwise in a truly excellent state. Dibner, Heralds of Science, 198; DSB X, p. 363; Garrison and Morton, 2472; Horblit, 82.AC
