Gabriel Grasset writes that he has received from Mr. Faure a manuscript copy of Histoire l’Etablissement du Christianisme by Mr. Mallé, secretary to Lord Bolingbroke. This work was pseudonymously written by Voltaire. Grasset says that he will print the text in octavo with wide margins and in fine type, and that he will provide two dozen well-bound copies to Mr. Faure in Geneva. The receipt is dated 1 June 1774.

In a postscript, Grasset promises not to sell any copies of the text in Geneva. Theodore Besterman notes that if the dates provided in this MS are correct, the composition of the work must be brought forward from 1777.
