René-Théophile LAENNEC. L.A.S., Paris March 25, 1807, to his father Théophile Laennec, member of the prefecture council of Finistère, in Saint-Brieuc; 1 page in-4, address on the back with red wax seal (broken; small tear due to breakage of seal). He thanks his father for the "Celtic mustard, which seemed to me of a very good taste". He has no place at the Court and does not seek one. "The only place I am aiming for is to be attached to the public teaching of medicine one day, and I cannot reasonably hope to get there before ten years. In the meantime, he is practicing medicine and still asking his father for money, because his patients are taking a long time to pay. He hopes to be in line for a position "that would attach me in a more special way than that of a member of the Society", but nothing is certain, and he asks his father not to speak "absolutely about this to anyone, to any living, speaking and thinking being"...
