That Dr. Buchanan did not mention his name is explained by the fact that he died only six months before; and the audience, who had doubtless read the obituary notice just recited, or a similar one, knew who was meant. Besides, he was a native African, and had no name worth having. He was only Negro Tom. In Bishop Gregoire's work, however, he is ennobled by the by the name of Thomas Fuller, and in Mr. Needles' Memoir the name of Thomas Tuller.[5] Why Dr. Buchanan should have omitted to mention the name of "the New Orleans physician" does not appear, unless it be that he was equally well known. His name, I have found recently, was James Derham. Dr. Rush, in the American Museum for January, 1789, gave an account of Dr. Derham, who was then a practitioner of medicine at New Orleans, and, at the time the notice was written, was visiting in Philadelphia. He was twenty-six years of age, married, member of the Episcopal Church, and having a professional income of three thousand dollars a year. He was born in Philadelphia a slave, and was taught to read and write, and occasionally to compound medicines for his master, who was a physician. On the death of his master he was sold to the surgeon of the Sixteenth British regiment, and at the close of the war was sold to Dr. Robert Dove, of New Orleans, who employed him as an assistant in his business. He manifested such capacity, and so won the confidence and friendship of his master, that he was liberated on easy terms after two or three years' service, and entered into practice for himself. "I have conversed with him," says Dr. Rush, "upon most of the acute and epidemic diseases of the country where he lives. I expected to have suggested some new medicines to him, but he suggested many more to me. He is very modest and engaging in his manners. He speaks French fluently, and has some knowledge of the Spanish."[6] It was unfortunate that these incidents had not occurred early enough to have come to the knowledge of Mr. Jefferson before he wrote his "Notes on Virginia." These were precisely the kind of facts he was in quest of. He probably would have used them, and have strengthened the opinions he there expressed as to the intellectual capacity of the negro race.
