Marie Jean Antoine Nicolas de Caritat, marquis de Condorcet (1743-1794)

Letters and notes by Condorcet, and associated documentation:

1. Letter, signed, 1776; recipient is given in an attached manuscript dealer's note as "M. Trudaine", but this may not be accurate. Concerning two sous-ingenieurs who have been working at Ribemont (Condorcet's birthplace), Condorcet's correspondence on the subject with M. Le Pelletier, and his intention to deliver a tribute to the recently deceased Linnaeus.

2. Letter, unsigned, undated, but endorsed 1781.

3. Notes, headed "Travaux Anatomiques." Undated.

4. Notes, headed "Interscendentes". 1762.

5. Notes, headed "Pieces fugitives interées dans le comentaire". Undated, but probably from the first half of 1780. This piece relates to Kehl's edition of Voltaire, published in seventy volumes from 1785 to 1789, the first complete edition of Voltaire's work to appear after his death.

6. Extract, manuscript, from the Registers of the Académie Royale des Sciences, recording work by M. Hassenfratz (presumably the scientist Jean Henri Hassenfratz (1755-1827)) on nutrition in plants, signed by Condorcet. 1792.

7. Note to an unnamed individual indicating how they should communicate whilst Condorcet is ill. 1775.
