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.

The collection includes a copy of a letter from Voltaire to Albrecht von Haller, baron Haller dated 13 February 1759. In the letter, Voltaire sends a certificate [wanting] to introduce Grasset who wishes for recipient’s protection. He then discusses a text printed at Lausanne which represents an abominable libel against the Moors, religion etc. He adds that he thinks recipient should refuse a protection to such a rascal, noting that the author of the libel is a man named Verlecke or Leveche, formerly teacher of M. Constant, and is minister of a village near Lausanne
