Dr. Franklin, though confined to his chamber, and suffering under a most painful disease, could not allow the occasion to pass without indulging his humor at the expense of Mr. Jackson. He wrote to the editor of the _Federal Gazette_, March 23, 1790, as follows: "Reading, last night, in your excellent paper, the speech of Mr. Jackson, in Congress, against their meddling with the affair of slavery, or attempting to mend the condition of the slaves, it put me in mind of a similar one made about one hundred years since by Sidi Mehemet Ibrahim, a member of the Divan of Algiers, which may be seen in Martin's Account of his Consulship, anno 1687. It was against granting the petition of a sect called _Erika_, or Purists, who prayed for the abolition of piracy and slavery as being unjust. Mr. Jackson does not quote it; perhaps he has not seen it. If, therefore, some of its reasonings are to be found in his eloquent speech, it may only show that men's interests and intellects operate, and are operated on, with surprising similarity, in all countries and climates, whenever they are under similar circumstances. The African's speech, as translated, is as follows." He then goes on to make an ingenious parody of Mr. Jackson's speech, making this African Mussulman give the same religious, and other reasons, for not releasing the white Christian slaves, whom they had captured by piracy, that Mr. Jackson had made for not releasing African slaves.[32] There were inquiries in the libraries for "Martin's Account of his Consulship," but it was never found. The paper may be read in the second volume of Franklin's Works, Sparks' edition, p. 518. None of Dr. Franklin's writings are more felicitous than this _jeu d' esprit_; and it was written only twenty-four days before his death.
