I have just performed my first professional cure, and am already dubbed Dr. Blackwell by the household. I mesmerised away a severe headache that afflicted Miss O’Heara, a kind-hearted, child-like, black-haired little old maid, the favourite of the family and especial pet of the children. She had just recovered from a very severe attack of illness, and great suffering in the mouth from calomel, which made her declare that no physician ought to receive his diploma till he has been salivated, that he may know the torture he is inflicting on his patients. I went into her room last night, and found her suffering from an intense throbbing headache. I offered to relieve her, half doubting my own powers, never having attempted anything of the kind; but in a quarter or half an hour she was entirely relieved, and declared some good angel had sent me to her aid. I have just returned from the Sunday-school which we have organised to-day for the slaves. When I first came here I determined to teach all the slaves I could to read and write, and elevate them in every way in my power, as the only way I could reconcile it to my conscience to live amongst them; but to my consternation I found that the laws forbade it, and that Dr. Dickson was not willing to evade them. Not the slightest effort was made to instruct them in any way, except that now and then a sermon was preached to them; but they had to labour on without a ray of light or hope. It was intolerable to me, and I proposed at last we should have Sunday-school, and give them real instruction; and as such a scheme had been talked of about a year ago, I found a few who were willing to engage in the undertaking. Accordingly, this afternoon at three o’clock we made a beginning—four ladies and one gentleman, with about twenty-five scholars; we have a class of men, women, boys, and two of girls. I take one of the latter, four girls, from eight to twelve years old. I assure you I felt a little odd, sitting down before those degraded little beings, to teach them a religion which the owners professed to follow whilst violating its very first principles, and audaciously presuming to stand between them and the Almighty. As I looked round the little room and saw those ladies holding forth to their slaves, fancying that now they were fulfilling every duty and were quite model mistresses, I longed to jump up, and, taking the chains from those injured, unmanned men, fasten them on their tyrants till they learned in dismal wretchedness the bitterness of that bondage they inflict on their brethren. But one person can do nothing. I sat quietly teaching, and reserved my indignation to vent on this inoffensive white paper. I am afraid much cannot be done for the slaves in
