 found peculiarly adapted to the wants of students who are without 

 the aid of a ^eacher. The Answers to the Examples, with hints 

 for the solution of some in which assistance may be needed, are 

 given at the end of the book. In the present edition two New 

 Chapters and Three hundred miscellaneous JExamples have been 

 added. "It has merits which unquestionably place it first in the

This treatise contains all the propositions which are usually included 

 in elementary treatises on the theory of Equations, together with 

 Examples for exercise. These have been selected from the College 

 and University Examination Papers, and the results have been 

 given when it appeared necessary. In order to exhibit a compre- 

 hensive view of the subject, the treatise includes investigations which 

 are not found in all the preceding elementary treatises, and also 

 some investigations which are not to be found in any of them. For 

 the second edition the work has been revised and some additions 

 have been made, the most important being an account of the 

 Researches of Professor Sylvester respecting Newton' s Rule. "A 

 thoroughly trustworthy, complete, and yet not too elaborate treatise."

The design of this work has been to render the subject intelligible 

 to beginners, and at the same time to afford the student the oppor- 

 tunity of obtaining all the information which he will require on 

 this branch of Mathematics. Each chapter is followed by a set 

 of Examples : those which are entitled Miscellaneous Examples, 

 together with a few in some of the other sets, may bi advantageously 

 reserved by the student for exercise after he has made some progress 

 in the subject. In the Second Edition the hints for the solution of 

 the Examples have been considerably increased.
