A TEXT-BOOK FOR THE SCIENCE OF SPACE BASED ON HILBERT'S FOUNDATIONS BY GEORGE BRUCE HALSTED FIRST EDITION FIRST THOUSAND NEW YORK JOHN WILEY & SONS LONDON: CHAPMAN & HALL, LIMITED PREFACE. WRITING to Professor Hilbert my desire to base a text-book on his foundations, he answered: "Ueber Ihre Idee aus meinen Grundlagen eine Schul-Geometrie zu machen, bin ich sehr erfreut. Ich glaube auch, dass dieselben sich sehr gut dazu eignen werden." Geometry at last made rigorous is also thereby made more simple. KENYON COLLEGE, GAMBIER, OHIO. GEORGE BRUCE HALSted. iii |
