borough and market town in Sussex, seated on the north-west side of the river Arun, over which there is a bridge. It had a harbour, wherein a ship of 150 tons burden might ride; but the sea had ruined it so far, that, in 1733, an act passed for repairing it, and for erecting new piers, locks, &c. The castle, which gives the title of earl to its possessors, is seated on the east of the Tame, and is reputed to be a mile in compass. It sends two members to parliament; and is 55 miles south-west-by-south of London, and 10 miles east of Chichester. Arundel is the premier earldom in England, belonging to the illustrious family of Norfolk; and is the only title in England that goes along with the lands. W. Long. o. 25. N. Lat. 50. 45.

ARUNDEL Oil, in the Materia Medica. At Bombay, Gombroon, and Surat, in the East Indies, there grows a tree which bears a nut enclosed in a rough husk, which resembles much the horse-chestnut; and the kernel of the nut yields an oil by expression, which is of a purgative nature. A tea-spoonful of it is reckoned a dose. The tree goes by the name of the arundel tree at Bombay, and its oil by that of the arundel oil. Mr Sinclair, one of the surgeons belonging to the royal regiment of artillery, who was formerly surgeon to an East India ship, gave Dr Monro of London a small bottle full of this oil, which he said was much used for the cure of the dysentery in India, and that he had given it in four recent cases of dysentery with success. Dr Monro thinks it probable that this is the oil of the purging nuts mentioned in Dale's Pharmacologia, which are got from the tree called lignum moluccense, pavonia diutium, fructu avellanae, J. B. i. 342; and pinus Indica, nucleo purgante, C. B. 402; and the palma Chrissi Indica, Tournefort Mat. Med.
