The author s principal intention is to explain difficulties which maybe 

 encountered by the student on first reading the Principia, and to 

 illustrate the advantages of a careful study of the methods employed 

 by Newton, by showing the extent to which they may be applied in 

 the solution of problems ; he has also endeavoured to give assistance 

 to the student who is engaged in the study of the higher branches oj 

 mathematics, by representing in a geometrical form several of the 

 processes employed in the Differential and Integral Calculus, and in 

 the analytical investigations of Dynamics. 



AN ELEMENTARY TREATISE ON CURVE TRACING. 



8\0. 1 2S. 



The author has written this book under the conviction that the skill 

 and power of the young mathematical student, in order to be 

 thoroughly available afterwards, ought to be developed in all possible 

 directions. The subject which he has chosen presents so many fads, 

 pointing in directions towards which the mind of the intended 

 mathematician has to radiate, that it would be difficult to find 

 another which, with a very limited extent of reading, combines, to 

 the same extent, so many valuable hints of methods of calculations 

 to be employed hereafter, with so much pleasure in its present use. 

 In order to understand the work it is not necessary to have much 

 knowledge of what is called Higher Algebra, nor of Algebraical 

 Geometry of a higher kind than that which simply relates to the 

 Conic Sections. From the study of a work like this, it is beliez'ed 

 that the student will derive many advantages. Especially he will 

 become skilled in making correct approximations to the values of 

 quantities, which cannot be found exactly, to any degree of accuracy 

 -which may be required. 



Frost and Wolstenholme. — a TREATISE ON SOLID 



GEOMETRY. By Percival Frost, M.A., and the Rev. J.

College. Svo. cloth. i8j. 



Intending to make the subject accessible, at least in the earlier portions 

 to all classes of students, the authors have endeavoured to explain 

 completely all the processes -which are most useful in dealing with 

 ordinary theorems ana problems, thus directing the student to the 

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

 problem. In the mere difficult portions of the subject, they have 

 considered themselves to be addressing a higher class oj' students ;
