EDMUND, an excellent English mathematician and astronomer, was born in Hertfordshire in 1681, and studied at Westminster-school; from whence he removed to Oxford, where he took the degree of master of arts in 1666, and afterwards entered into holy orders. In 1615 he took the degree of bachelor of divinity; but being peculiarly eminent for his knowledge in the mathematics, he had two years before been chosen professor of astronomy in Gresham-college, London; where he distinguished himself by his lectures and writings. He invented a small portable quadrant; and also the famous line of proportions, which, after the inventor, is called Gunter's scale. He likewise published Canon Triangulorum; and a work entitled Of the Sector, Cross-staff, and other Instruments. This last was published, with an English translation of his Canon Triangulorum, in 4to, by Samuel Foster professor of Gresham college. Mr Gunter died at that college in 1626.
