a town of Northumberland, on the coast, situated north-west of Tynemouth, where Lord Delaval has constructed a pretty haven, whence coals are shipped for London. Here are large salt works and copperas works, and likewise considerable glass works; and there is here a canal cut through a solid rock to the harbour, 52 feet deep, 30 broad, and 900 long. These works are the sole property of Lord Delaval, and yield a revenue of above 20,000l. per annum.

Hartley, David, M. A. born at Ilkleyworth, where his father was curate, received his academical education at Jesus college, Cambridge, of which he was a fellow. He first began to practise physic at Newark, in Nottinghamshire; from whence he remo- Hartogia wed to St Edmund's Bury, in Suffolk. After this, he settled for some time in London; and lastly went to live at Bath, where he died in 1757, aged 53, leaving two sons and a daughter. He published "A view of the present evidence for and against Mrs Stephen's* medicines as a solvent for the stone, containing 155 cases, with some experiments and observations," London 1739. He is said to have also written against Dr Warren, of St Edmund's Bury, in defense of inoculation; and some letters of his are to be met with in the Philosophical Transactions. The doctor was certainly a man of learning, and reputed a good physician; but too fond of nostrums. But his most considerable literary production is a work entitled, "Observations on man, his frame, his duty, and his expectations, in two parts;" London, 1749, 2 vols. 8vo. The first part contains observations on the frame of the human body and mind, and on their mutual connections and influences. The second part contains observations on the duty and expectations of mankind.
