[The art of Toulouse-Lautrec and medicine].

After mentioning the numerous designs done by Henri Toulouse-Lautrec, in 1891, in Péan's surgical department, the author presents and explains a lithography published in 1897 in Georges Clemenceau's book "Au pied du Sinaï". The particular story it was to illustrate relates "how I became presbytic" ("Comment je devins presbyte") and shows the ophthalmologist Mayer prescribing reading glasses to Clemenceau.
