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

 to beghiners, and at the same time to afford the student the oppor* 

 tunity of obtaining all the information tvMch he will require on 

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

 of Exampi,es : those which are entitled Miscellaneous Examples, 

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

 reserved by the student for exeixise 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,

 account of Napier'' s Rules of circular parts, an explanation has 

 been given of a method of proof devised by Napier, which seems to 

 have been overlooked by most modern writers on the subject. Con- 

 siderable labour has been bestotved on the text in order to render it 

 comprehensive and accurate, and the Examples (selected chiefly 

 from College Examination Papers) have all been carefully verified,

The author has here endeavoured to exhibit the subject in a simple 

 manner for the benefit of beginners, and at the sa?ne time to include
