PREFACE.

The present edition of Euclid's Elements of Geometry, like most of its contemporaries, is based on the invaluable work of Dr Simson. Its leading characteristics are the following: (a) In all the propositions, a clear line of demar

cation is drawn between the construction and

the proof or demonstration. (6) By a typographical expedient, the several steps

in the reasoning are clearly shown. (c) In describing the figures, those parts which are

given in the enunciation are represented by dark lines, and those which are added in the

course of the demonstration by dotted lines. (d) In all cases, the figure has been repeated,

wherever it was found necessary.

With the foregoing aids, the present Euclid cannot fail to be of very great service to every student of Geometry.
