This edition of the Elements of Euclid, undertaken at the request of the principals of some of the leading Colleges and Schools of Ireland, is intended to supply a want much felt by teachers at the present day -- the production of a work which, while giving the unrivaled original in all its integrity, would also contain the modern conceptions and developments of the portion of Geometry over which the Elements extend.
