Cheyne. — Works by C. H. H. Cheyne, M.A., F.R.A.S.:— 



AN ELEMENTARY TREATISE ON THE PLANETARY 

 THEORY. With a Collection of Problems. Second Edition. 

 Crown 8vo. cloth. 6.r. 6d. 



In this volume, an attempt has been made to produce a treatise on the 

 Planetary theory, which, being elementary in character, should be 

 so far complete as to contain all that is usually required by students 

 in the University of Cambridge. This Edition has been carefully 

 revised. The stability of the Planetary System has been more fully 

 treated, and an elegant geometrical explanation of the formula: for 

 the secular variation of the node and inclination has been in- 

 troduced. 



THE EARTH'S MOTION OF ROTATION. Crown 8vo. 

 3-r. bd. 



The first part of this work consists of an application of the method oj 

 the variation of elements to the general problem of rotation . In the 

 second part the general rotation formula: are applied to the particular
