 PLES IN MATHEMATICS. With Answers. By H. A. 

 Morgan, M.A., Sadlerian and Mathematical Lecturer of Jesus 

 College, Cambridge. Crown 8vo. cloth. 6j. 6d. 



This book contains a number of problems, chiefly elementary, in the 

 Mathematical subjects usually read at Cambridge. They have been 

 selected fmm the Papers set during late years at Jesus College. Very

Newton's Principia.— 4t0 . cloth. 3 u. 6d. 



It is a sufficient guarantee of the reliability of this complete edition of 

 Neivtoris Principia that it has been printed for and under the care 

 of Professor Sir William Thomson and Professor Blackburn, of 

 Glasgow University. The following notice is prefixed :— ' ' Finding 

 that all the editions of the Principia are now out of print, we have 

 been induced to reprint Newton's last edition [of 1726] without note

 with large type, fine thick paper, and cleanly-cut figures, and is 

 the only recent edition containing the whole of Newton's great 

 work.

AN ELEMENTARY TREATISE ON MECHANICS. For the 

 Use of the Junior Classes at the University and the Higher Classes 

 in Schools. With a Collection of Examples. Fourth Edition, 

 revised. Crown Svo. cloth. 95. 6d. 



In preparing a fourth edition of this work the author has kept the 

 same object in view as he had in the former editions — namely, to in- 

 clude in it such portions of Theoretical Mechanics as can be con- 

 veniently investigated without the use of the Differential Calculus, 

 and so render it suitable as a manual for the junior classes in the 

 University and the higher classes in Schools. With one or two short 

 exceptions, the student is not p7-esumed to require a knowledge of any
