[Franco-Mexican medical action and the Mexican Expedition (1864-1867)].

In the days when French expeditionary troops were fighting in Mexico, Napoleon the Third founded a "Mexican Scientific Committee" in the same wave length as his uncle, General Bonaparte in Egypt. The Committee was headquartered in Paris and since April 1864, a "Franco-Mexican Committee" took place at Mexico-City. The medical branch was led, in Paris, by the Baron Hippolyte Larrey and chaired on the spot by Dr Ehrmann; it will become the "Academia de Medicina de Mexico" and published the "Gaceta Medica". Numerous researchs were undertaken and most of them printed in the "Gaceta Medica" with some regards to many diseases, particuliarly Yellow Fever and Typhus. The Academia and Gaceta will last long after war ending and, in 1970, a special session was hallowed to their foundation, more than one century before.
