Dunstan wrote many chem ical papers, notably on the pharmacology of the alkaloids, and on the aconite alkaloids in particular. He was concerned in the identi fication of the new mineral, thorianite, which he isolated during an examination of the minerals of Ceylon.

During his term of office as director of the Imperial Institute, Dunstan visited Cyprus, Asia Minor, India and New foundland at the request of the Colonial Office. Reports on agri cultural and mineral resources were presented to parliament.

DUNSTER, a market town in the Bridgwater parliamentary division of Somersetshire, England, i - m. from the shore of the Bristol channel, on the Minehead branch of the G.W. railway. Pop. of civil parish (1921) 705. Its streets, sloping sharply, con tain many old houses. On an eminence stands the ancient castle, with its two massive gateways of the i3th and i sth centuries and other early portions, though it has been restored and modernized as a residence. The church of St. George, with its fine tower, is mainly Perpendicular, but has Norman and Early English portions. Near the church are traces of the Benedictine house to which it was attached. The Yarn market, a picturesque octagonal building with deep sloping roof, in the main street, dates from c. 1600. There were British, Roman and Saxon settlements at Dunster (Torre Dunestorre, Dunester), fortified against the piracies of the Irish Northmen. The Saxon fort of Alaric was replaced by a Nor man castle, dating from the Domesday Survey, built by William de Mohun, first lord of Dunster, who founded the priory of St. George. Before 1183, Dunster had become a mesne borough, owned by the de Mohuns until the i4th century when it passed to the Luttrells, the present owners. Reginald de Mohun granted the first charter between 1245 and 1247. John de Mohun granted other charters in 1301 and 1307. Dunster was represented in parliament in conjunction with Minehead, one of its tithings being part of that borough. Representation began in 1562, and was lost in 1832. During this time the port had a considerable wool, corn and cattle trade with Ireland. In the middle ages the Friday mar ket and fair in Whit week, granted by the first charter, were cen tres for the sale of yarn and cloth called "Dunsters," made in the town. With the silting up of the harbour, its importance as a port disappeared. An i8th century tower on Conegar hill forms a well-known landmark.
