This is owing, mainly, to two causes: discoveries in the higher mathematics have thrown new light upon the elements of the science; and the demands of schools, in all enlightened nations, have called out many works by able mathematicians and skillful Professor Hayward, of Harvard University, as early as 1825, defined parallel lines as lines having the same direc-tion. Euclid's definitions of a straight line, of an angle, and of a plane, were based on the idea of direction, which is, in-deed, the essence of form. This thought, employed in all these leading definitions, adds clearness to the science and simplicity to the study. In the present work, it is sought to combine these ideas with the best methods and latest discoveries of the most distinguished writers on Geometry. By careful arrangement of topics, the theory of each class of figures is given in uninterrupted connection. No attempt is made to exclude any method of demonstration, but rather to present examples of all. In explaining the doctrine of limits, the axiom stated by Dr. Whewell is given in tho words of that eminent scholar. The books most freely used are, "Cours de géométrie Glémentaire, par 4. J. H. Vincent et M. Bourdon;" " Gé-ométrie théorique et pratique, etc., par H. Sonnet;" " Die reine elementar-mathematik, von Dr. Martin Ohm;" and "Treatise on Geometry and its application to the Arts, by Rev. D. Lardner." Occasional use has been made of the works of Schlömilch, Briot, Bobillier, Leslie, and Lund; also, of Blanchet's edition of Legendre, Prouhet's edition of Lacroix, and Law's and Lardner's editions of Euclid. The works of Bland, Colenso, and Potts have been used for the selection of exercises. A large portion of the work has been used in class in-struction, and the author takes pleasure in acknowledging that many valuable hints have been received from his pupils. The subject is divided into chapters, and the articles are numbered continuously through the entire work. The convenience of this arrangement for purposes of reference, has caused it to be adopted at the present day by a large majority of writers upon Geometry, as it had been already by writers on other scientific subjeets. If this treatise shall contribute to render the study of Geometry less complex, and more interesting to the student, and hence lead to a wider cultivation and more thorough knowledge of this branch of mathematics, the chief object of the author in its preparation will have been accom-plished.
