Series III contains a manuscript volume which appears to be unrelated to Usher, Lawrence, or Haiti. It is written in various hands and opens with records of meetings of the Committee of Ways and Means of the New York State Legislature held between February 6 and April 7, 1863. The minutes are followed by a manuscript translation of Les sectes et sociétés secrètes, politiques et religieuses: essai sur leur histoire depuis les temps les plus reculés jusqu'à la Révolution française (titled "Sects and Secret Societies, both Political and Religious"), by Jean Baptiste Emmanuel Hector, comte Le Couteulx de Canteleu, which was published in 1863.
