LS in French, signed “L. Pasteur,” one page both sides, 8.5 x 10.75, October 7, [1883]. Untranslated letter to "Monsieur Mancuer," with six lines in Pasteur's hand on the reverse commenting on the vaccination of swine. In very good to fine condition, with scattered staining, two small chips to the left edge, and a short split to the end of the horizontal fold. Accompanied by the original mailing envelope.

In 1882, Pasteur sent his assistant Louis Thuillier to southern France because of an epidemic of swine erysipelas, commonly called 'diamond skin disease.' Thuillier identified the bacillus that caused the disease in March 1883. Pasteur and Thuillier increased the bacillus's virulence after passing it through pigeons, then passed it through rabbits, weakening it and obtaining a vaccine.
