Collection consists of 10 holograph documents (letters, reports and financial agreements) concerning the writing of Lépecq
de la Cloture's 2 v. book (Collection d'observations sur les maladies et constitution épidémiques. De l'Imprimerie privilégiée;
et se trouve a Paris: Chez Didot le jeune ... [Chez] Méquignon, 1778), and supporting modern research material. The letters
chiefly discuss the business of payment for, distribution of, and reaction to Lépecq's work on the epidemiology of Normandy;
and his difficulties in arranging royal support from the agents of King Louis XVI, the patron of the first two vol., for publication
of a third volume.
