De l'Atténuation des virus, avec la collaboration de MM. Chamberland, Roux et Thuillier. Quatrième Congrès international d'hygiène et de démographie. Séance du 5 Septembre 1882

Very rare first edition printed in a small number of copies of this offprint from the Fourth International Congress of Hygiene and Demography, session of 5 September 1882.

Spine and boards slightly faded and yellowed at the margins; interior in pleasing condition.

In this communication, Louis Pasteur examines all the new studies carried out in collaboration with Chamberland, Roux and Thuillier since the publication of the 1880 memoir.

Its principal purpose is to provide examples of the attenuation of viruses under the influence of atmospheric oxygen. He also summarizes the criticisms that had appeared in the collected works of the German Sanitary Office.
