"Mr. Willis, a rich American planter, settled in Florida," said Murphy, "had discovered in one of his young black slaves, named David, who was employed in the infirmary attached to his dwelling, a very remarkable degree of intelligence, combined with a constant and deep commiseration for the sick poor, to whom he gave, with the utmost attention and care, the medicine ordered by the doctors, and, moreover, so strong a prepossession for the study of botany, as applied to medicine, that without any tuition he had composed and classified a sort of flora of the plants around the dwelling and the vicinity. The establishment of Mr. Willis, situated on the borders of the sea, was fifteen or twenty leagues from the nearest town; and the medical men of the district, ignorant as they were, gave themselves no great deal of care or trouble, in consequence of the long distance and the difficulty in procuring any means of conveyance. Desirous of remedying so extreme an inconvenience in a country subject to violent epidemics, and to have at hand at all times a skilful practitioner, the colonist made up his mind to send David to France to learn surgery and medicine. Enchanted at this offer, the young black set out for Paris, and the planter paid all the expenses of his course of study. David, having for eight years studied with great diligence and remarkable effect, received the degree of surgeon and physician with the most distinguished success, and then returned to America to place himself and his skill under the direction of his master." "But David ought to have considered himself free and emancipated, in fact and in law, when he set foot in France." "David's loyalty is very rare: he had promised Mr. Willis to return, and he did so. He did not consider as his own the instruction which he had acquired with his master's money; and, besides, he hoped to improve morally as well as physically the sufferings of the slaves, his former companions; he trusted to become not only their doctor, but their firm friend and defender with the colonist." "He must, indeed, be imbued with the most unflinching probity and the most intense love for his fellow creatures to return to a master,--an owner,--after having spent eight years in the midst of the society of the most democratic young men in Europe."
