This Geometry introduces the student systematically to the solution of geo- 

 metrical exercises. It provides a course which stiniulati;s him to do original 

 work and, at the same time, guides him in putting forth his efforts to the best 

 advantage. 



The Schultze and Sevenuak Geometry is in use in a large number of the 

 leading schools of the country. Attention is invited to the following impor- 

 tant features : i. i^rcliiniiiary Propositions are presented in a simple manner ; 

 2. The numeruus and well-graded Exercises —jwoxt than 1200 in number in 

 the complete book. These are introduced from the beginning; 3. State- 

 ments from whicli General Principles may be obtained are inserted in the 

 Exercises, under the heading " Remarks "; 4. Proofs that are special cases 

 of general principles obtained from the Exercises are not given in detail. 

 Hints as to the manner of completing the work are inserted ; 5. The Order 

 of Propositions \i2A a distinct pedagogical value. Propositions easily under- 

 stood are given fh"st and more difficult ones follow; 6. 'J'he Analysis of 

 Problems and of Theorems is more concrete and practical than in any other 

 text-book in Geometry; 7. Many proofs are presented in a simpler and 

 more direct manner than in most text-books in Geometry ; S. Difficult Prop- 

 ositions are made somewhat easier by applying simple Notation; 9. The 

 Algebraic Solution of Geometrical Exercises is treated in the Appendix to the 

 Plane Geometry; 10. Pains have been taken to give Excellent Figures 

 throughout the book.

This key will he helpful to teachers who cannot give sufficient time to the 

 solution of the exercises in the text-book. Most solutions are merely out- 

 lines, and no attempt has been made to present these solutions in such form 

 that they can be used as models for class-room work.
