Pasteur (Louis, chemist, 1822-95) Autograph Letter signed [to Walter Raleigh Browne], in French, 1p. with conjugate blank, 8vo, Paris, 10th December 1881, declining to write an article for Browne on account of pressing laboratory work and because he needs to write a speech in consequence of his recent election to Académie Française, folds.

⁂ In this year Pasteur was very much taken up with his work on developing a vaccine for the prevention of anthrax in animals. The vaccine was successfully demonstrated later in the year. Less than a week before the date of the present letter he had drafted a letter to Baron Kemeny about the preparation and distribution of the vaccine, promising to be able to distribute it the following spring at a "modest" price.

Walter Raleigh Browne (1842-84), civil engineer and Christian writer.
