Guichainville informs Brownson that a M. Ponce de Leon has shown him a lithographic facsimile of the autograph. He mentions that this signature was found under a work having for title: "Codice Diplomatico Columbo Americano" Second Edition, published in January 1857. Another one was published in 1867 in Havana illustrated on page 291. Also, that a Samuel Barlow informed Guichainville that these two facsimiles were executed by a man named La Croix, sometimes called "Enrico Croce". Guichainville does not know whether facsimiles of Columbus' letters were made but he can not reconcile the fact that no authorization was given for their production. He is not satisfied with the person recommended by W. E. Curtis. However, Guichainville promises him to write to Curtis asking him what day he will arrive in New York. In reference to the "History of Columbus" Guichainville suggests that it may be a continuation of the work of Samuel Barlow. Nevertheless, he counsels Brownson to wait and see. He closes assuring Brownson of his most devoted sentiments. :: III-3-d A.L.S. French 4pp. 12mo.
