In the 'Charleston (South Carolina) Mercury' of October 12, 1838, we find an advertisement of half a column, by a Dr. T. Stillman, setting forth the merits of another 'Medical Infirmary,' under his own special supervision, at No. 110 Church street, Charleston. The doctor, after inveighing loudly against 'men totally ignorant of medical science,' who flood the country with quack nostrums backed up by 'fabricated proofs of miraculous cures,' proceeds to enumerate the diseases to which his 'Infirmary' is open, and to which his practice will be mainly confined. Appreciating the importance of 'interesting cases,' as a stock in trade on which to commence his experiments, he copies the example of the medical professors, and advertises for them. But, either from a keener sense of justice, or more generosity, or greater confidence in his skill, or for some other reason, he proposes to _buy up_ an assortment of _damaged_ negroes, given over as incurable by others, and to make such his 'interesting cases,' instead of experimenting on those who are the 'property' of others. Dr. Stillman closes his advertisement with the following notice:— "TO PLANTERS AND OTHERS.—Wanted, _fifty negroes_. Any person having sick negroes, considered incurable by their respective physicians, and wishing to dispose of them, Dr. S. will pay cash for negroes affected with scrofula or king's evil, confirmed hypocondriasm, apoplexy, diseases of the liver, kidneys, spleen, stomach and intestines, bladder and its appendages, diarrhœa, dysentery, &c. The highest cash price will be paid on application as above."
