MATHEMATICS, 



The authors have endeavoured to. present before students as comprehensive 

 a view of the subject as possible. Intending to make the subject accessible, 

 at least in the earlier portion, to all classes of students, they have endea- 

 voured to explain completely all the processes "which are most useful in 

 dealing with ordinary theorems and problems, thus directing the student 

 to the selection of methods which are best adapted to the exigencies of each 

 problem. In the more difficult portions of the subject, they have considered 

 themselves to be addressing a higher class of students ; and they have there 

 tried to lay a good foundation on which to build, if any reader should 

 wish to pursue the science beyond the limits to "which the work extends. 



Godfray. A TREATISE ON ASTRONOMY, for the Use of 

 Colleges and Schools. By HUGH GODFRAY, M.A., Mathematical 

 Lecturer at Pembroke College, Cambridge. 8vo. cloth. \2s. 6d. 



This book embraces all those branches of Astronomy which have, from 

 time to time, been recommended by the Cambridge Board of Mathematical 

 Studies : but by far the larger and easier portion, adapted to the first three 

 days of the Examination for Honours, may be read by the more 

 advanced pupils in many of our schools. The author's aim has been to 

 convey clear and distinct ideas of the celestial phenomena. 



AN ELEMENTARY TREATISE ON THE LUNAR THEORY, 

 with a Brief Sketch of the Problem up to the time of Newton. 

 By HUGH GODFRAY, M.A. Second Edition, revised. Crown 

 8vo. cloth. $s. dd. 



These pages will, it is hoped, form an introduction to more recondite 

 works. Difficulties have been discussed at considerable length. The 

 selection of the method followed with regard to analytical solutions, 

 which is the same as that of Airy, Herschel, &^c. was made on account 

 of its simplicity ; it is, moreover, the method which has obtained in the 

 University of Cambridge.
