[On the discovery of the parasite of malaria by A. Laveran: Bône 1878 - Constantine 1880].

Books published on malaria and parasites do not mention the exact place and date of the discovery of the hematozoa. We think it is important to specify this point of the history of medicine. From Laveran's three main writings about this subject, the first one written on the 8th of November 1880 was summarized at the "Académy de Médecine" on the 23rd of November by Colin but never published. We got it from the archives. The parasite of malaria, Laveran's great discovery, was the result of a patient work and long microscopic examinations which started in Bône in 1878 where he first saw pigmented and crescent shaped bodies of Plasmodium falciparum. Then, on November 6, 1880 in Constantine, he was definitively convinced when he saw pigmented spherical bodies with flagella, that is to say exflaggelations. Nearly ten years passed before this etiology was universally admitted.
