The book aims at giving a pupil who has already mastered the portions 

 of Euclid usually read, most of the pure geometry required for an honours 

 degree at Oxford, Cambridge, London, or Manchester. The subject has 

 been considered primarily from the projective point of view, but consider- 

 able trouble has been taken to deduce the more important metrical pro- 

 perties of conies from the projective theorems with which they are 

 related, 



In these days, when the analytical method seems to hold the field in 

 mathematics, the author hopes that the book may encourage the student 

 to pay due attention to the methods of pure geometry, ten years' experience 

 as examiner in the university of London having shewn him the value of a 

 mastery of the principles of pure geometry. 



"The student whose tastes lie in the direction of pure geometry will find here a 

 mass of excellent material upon which he can exercise his faculties." — Sihool ll'orUi 



Architectural and Building Construction Plates. Part L Thirty draivlngs

These drawings, which form the first volume of The Cambridge Technical 

 Series (see p. 30), were prepared by the author as a basis for a series of 

 Lectures upon Building Construction, and are intended to cover an -ele- 

 mentary course of instruction in that subject. The examples have been 

 carefully chosen from work actually carried out under the direction of the 

 author, and will form a progressive series of drawings adapted to the 

 requirements of architectural and building students just entering upon their 

 professional studies. 



In some cases, the plates will form a ready source of reference, both for 

 architect and builder, upon items of construction not readily found in 

 text books. 



For teachers of building construction the plates, supplemented by 

 models, carefully made from the data given, will be found most useful 

 in imparting knowledge of what is, admittedly, a difficult subject. 



The drawings illustrate Brickwork, Excavating, Masonry, Carpentry, 

 "Joinery, Roof Coverings, Plumbing, and Standard Steel and b'on Sections.
