Catalogue Note

RARE: no copy in the British Library. The author, a teacher of mathematics in London, here claims to have invented a horizontal dial which made it possible to tell the time and establish the place of the sun without difficult calculations. His book inaugurated a bitter quarrel with William Oughtred and with Oughtred's pupil, William Forster, over the true inventor of the instrument.
