or ECLUSE, CHARLES II.**, a celebrated botanist, born at Arras, Feb. 18, 1526. He had been intended for the profession of the law, but disliking this study, he went to Montpellier, where he became the pupil of the naturalist Rondelet, and took the degree of M.D. From France he travelled into different parts of Europe, and on his return to Antwerp began to publish his botanical researches. The Emperor Maximilian II. appointed him to the direction of the botanical garden at Vienna; and there he remained until a court cabal drove him from his situation in 1587, and obliged him to seek an obscure retreat at Frankfort-on-the-Main. Thence he was called in 1593 to occupy the chair of botany at Leyden. The life of Clusius was one of much bodily suffering. In a botanical excursion in early life he had the misfortune to dislocate his ankle and hip joint, and to fracture his thigh, which rendered him lame. In after years he became dropsical, and had vesical disease, which occasioned him much bodily suffering; yet his mental activity was undiminished, and he continued to teach and write till within a short period of his death, which took place at Leyden April 4, 1609. His botanical works are remarkable for the time he flourished; and he translated several from the Latin into French and Spanish.
