Dr. Mantell, a number of years ago, sustained a severe injury on the spine, in consequence of a fall from his carriage, and an incurable tumor arose, which, by its pressure upon the nerves of the spinal chord, produced at first temporary paralysis, and subsequently through life, frequent and intense neuralgic suffering, attended by great emaciation. Still his powerful and enthusiastic mind rose above his sufferings, although they often deprived him of sleep. He wrote several of his works while he was a martyr to pain; at the same time he continued his professional visits, and at the bed side of his patients, and when in society at home or abroad, he assumed a degree of cheerfulness which might have led any one to suppose that he was in perfect health. During the last week of his life he suffered intensely, and was deprived almost entirely of sleep; still, although observed to look unusually ill, he gave a public lecture, with his usual animation, two days before his exit, and visited his patients the very day before he died.
