MA THE MA TICS. 2 9 



Todhunter (I.) continued. 



determining the subjects to be included and the space to be assigned to each, 

 the Author has been guided by the papers given at the various examinations 

 in elementary Algebra which are now carried on in this country. The 

 book may be said to consist of three parts. The first part contains the 

 elementary operations in integral and fractional expressions ; the second 

 the solution of equations and problems ; the third treats of various subjects 

 which are introduced but rarely into examination papers, and are more 

 briefly discussed. Provision has at the same time been made for the 

 introduction of easy equations and .problems at an early stage for those 

 who prefer such a course.

Intended to serve as an introduction to the larger treatise on Plane 

 Trigonometry, published by the Author. The same plan has been adopted 

 as in the Algebra for Beginners : the subject is discussed in short chapters, 

 and a collection of examples is attached to each chapter. The first fourteen 

 chapters present the geometrical part of Plane Trigonometry ; and contain 

 all that is necessary for practical purposes. The range of matter included 

 is such as seems required by the various examinations in elementary Tri- 

 gonometry which are now carried on in the country. Answers are appended 

 at the end.

Intended as a companion to the two preceding books. The work forms 

 an elementary treatise on demonstrative mechanics. It may be true that 

 this part of mixed mathematics has been sometimes made too abstract and 

 speculative ; but it can hardly be doubted that a knowledge of the elements 

 at least of the theory of the subject is extremely valuable even for those
