“Mr. La Beaume’s father, who lived in the East Indies, employed the lotion of the malic acid for many years; and at the time of his death, when he was upwards of seventy years of age, he had not lost one tooth, and all were not only sound, but firmly fixed in their sockets. He also employed regularly the levigated areca charcoal, and vinegar diluted with water, which Mr. La Beaume constantly uses.”
