COTES, ROGER (1682-1716), English mathematician and philosopher, the son of a clergyman, was born at Burbage, Leicestershire, on July I o, 1682. He was educated at St. Paul's school and Trinity college, Cambridge, and in I706 became Plum ian professor of astronomy and experimental philosophy at Cam bridge. He died on June 5, 1716, at the age of 34. Newton is reported to have said : "If Cotes had lived, we should have known something." His papers were published by his cousin and successor in the Plumian chair, Dr. Robert Smith, as Har monic Mensurarum (1722).
a maritime department of the north west of France, formed in 1790 from the northern part of the province of Brittany, and bounded north by the English Channel, east by the department of Ille-et-Vilaine, south by Morbihan, and west by Finistere. Pop. (1931) 539,531. Area, 2,786 square m. It consists of much denuded Devonian, Silurian and Cambrian rocks with granitic intrusions. The higher parts in the interior form the watershed between the rivers running respectively to the Channel and to the Atlantic Ocean. The rivers of the Channel slope are the Rance, Arguenon, Gouessan, Gouet, Frieux, Treguier and Leguer, while the Blavet, Meu, Oust and Aulne belong to the southern slope. In the south-east are the Landes du Menez which run in a north-westerly direction, while further west the watershed bifurcates to form the Montagnes Noires in the south-west and the Monts d'Arree in the west of the department. Both these lines are continued into Finistere. Exposure to strong rain-bearing winds from the Atlantic and a thin soil limit agriculture on the interior plateaux which pasture cattle and horses. Seaweed manure promotes coastal agriculture with wheat, oats and buckwheat as the chief crops, also potatoes, flax, mangels, apples, plums, cherries and honey. Paimpol equips a large fleet which sets out annually for the Icelandic fishing grounds. Sardines are caught locally and large quantities are preserved. The department produces slate, building-stone, lime and china-clay. Flour-mills, saw-mills, sardine factories, tanneries, iron-works, manufactories of polish, boat building yards and rope-works employ many people and cloth, agricultural implements and nails are manufactured. The chief imports are coal, wood and salt. Exports include agricultural pro ducts (eggs, butter, vegetables, etc.), horses, flax and fish. The chief commercial ports are Le Legue and Paimpol. The depart ment is served by the Ouest-Etat railway; its chief waterway is the canal from Nantes to Brest which traverses it for 73 miles.
Cotes-du-Nord is divided into the four arrondissements of St. Brieuc, Dinan, Guingamp and Lannion which contain 48 cantons and 390 communes. Bas Breton is spoken in the arrondisse ments of Guingamp and Lannion, and in part of that of St. Brieuc. The department belongs to the ecclesiastical province, the academie (educational division), and the appeal court of Rennes, and is in the region of the X. army corps. Extensive remains of an abbey of the Premonstratensian order, dating chiefly from the 13th century, exist at Kerity; and Lehon has remains of a priory of the same period. The churches of Ploubezre (12th, 14th and i6th centuries), Perros-Guirec (12th century), Plestin-les-Greves (i6th century) and Lanleff (12th century) are of interest. The church of St. Mathurin at Moncontour, a celebrated place of pilgrimage, contains fine stained glass of the i6th century, and the mural paintings of the chapel of Kermaria-an-Isquit near Plouha, which belongs to the i3th and 14th centuries, are well known. Near Lannion is the ruined castle of Tonquedec, built in the 14th century. At Corseul there is a temple and other Roman remains. (See also DINAN, GUINGAMP, LAMBALLE, and TREGUIER.)
