Ebook: Modern Pure Solid Geometry

The scope of this book is more limited than its title indicates. The nine chapters deal respectively with preliminary ideas, trihedral angles, skew quadrilaterals, tetrahedra, transversals, oblique cones, spheres, inversion, and recent geometry of the tetrahedron. The treatment is synthetic; but excluding anharmonic ratios, involution, conies, and even the complete quadrilateral. On the other hand, the author uses the concept of the imaginary sphere. The book may be criticised for its limited scope, but it is a useful collection of theorems on elementary topics. In particular, the chapters on tetrahedra bring together information not readily accessible elsewhere.Modern Pure Solid Geometry. -- From review.
