In his long career he occupied various places of honor and importance in the profession, he was visiting physician to the New York hospital from 1819 till 1834, and consulting physician after that year: became a fellow of the College of physicians and surgeons in 1820 ; was its vice-president from 1827 until 1855; its president from 1855 till 1858; and president of the New York academy of medicine in 1852. He was also professor of anatomy and physiology in Queen's (now Rutgers) College, New Jersey, from 1812 till 1826. Dr. Cock was long an active member, and at his death a vice-president, of the American Bible society. Infirmity and ill health compelled him to retire from practice some years before his death.
