John Ewing, an American clergyman, born in Nottingham, Md., June 22, 1732, died in Philadelphia, Sept. 8, 1802. He was educated in the college of New Jersey, was tutor in that college and instructor of the philosophical classes in the college of Philadelphia, and in 1759 became pastor of the first Presbyterian church in Philadelphia. In 1773 he visited England, and had interviews with Dr. Robertson, Lord North, and Dr. Johnson; the last of whom, affirming that the Americans were as ignorant as rebellious, said to Dr. Ewing, You never read. You have no books there." Pardon me," was the reply, we have read the ' Rambler.' When the college of Philadelphia was changed in 1779 to the university of Pennsylvania, Dr. Ewing was placed at its head as provost, and remained in this station together with his pastorate till his death. He was vice president of the American philosophical society, and made several contributions to its Transactions." His collegiate lectures on natural philosophy (2 vols., 1809) and a volume of sermons were published after his death.
