Routh. AN ELEMENTARY TREATISE ON THE DYNA- 

 MICS OF THE SYSTEM OF RIGID BODIES. With 

 numerous Examples. By EDWARD JOHN ROUTH, M.A., late 

 Fellow and Assistant Tutor of St. Peter's College, Cambridge ; 

 Examiner in the University of London. Second Edition, enlarged. 

 Crown 8vo. cloth. 14^. 



In this edition the author has made several additions to each chapter: 

 he has tried, even at the risk of some little repetition, to make each 

 chapter, as far as possible, complete in itself, so that all that relates 

 to any one part of the subject may be found in the same place. This 

 arrangement will enable every student to select his own order in 

 which to read the subject. The Examples which will be found at 

 the end of each chapter have been chiefly selected from the Examina- 

 tion Papers which have been set in the University and the Colleges 

 in the last few years.

 CAL TRIGONOMETRY ; with the Construction and Use of 

 Tables of Logarithms. By J. C. SNOWBALL, M.A. Tenth 

 Edition. Crown 8vo. cloth, 'js. 6d. 



In preparing the present edition for the press, the text has been sub- 

 jected to a careful revision ; the proofs of some of the more import- 

 ant propositions have been rendered more strict and general ; and 

 a considerable addition of more than two hundred examples, taken 

 principally from the questions set of late years in the public exami- 

 nations of the University and of individual Colleges, has been made 

 to the collection of Examples and Problems for practice.
