manner the leading propositions of the science, and to illustrate and 

 apply those propositions in practice. In the practical part of the 

 subject he has advanced somewhat beyond the majority of preceding 

 writers ; particularly in Division, in Greatest Common Measure, 

 in Cube Root, in the chapters on Decimal Money and the Metric 

 System, and more especially in the application of Decimals to Per- 

 centages and cognate subjects. Copious examples, original and 

 selected, are given.

 CAL TRIGONOMETRY ; with the Construction and Use of 

 Tables of Logarithms. By J. C. SNOWBALL, M.A. Tenth 

 Edition. Crown Svo. cloth, "js. 6d. 



In preparing the present edition for the press, the text has been sub- 

 jected to a careful revision ; the proofs of some of the more import- 

 ant propositions have been rendered more strict and general ; and 

 a considerable addition of more than two hundred examples, taken 

 principally from the questions set of late years in the public exami- 

 nations of the University and of individual Colleges, has been made 

 to the collection of Examples and Problems for practice. 



Tait and Steele. DYNAMICS OF A PARTICLE. With 



numerous Examples. By Professor TAIT and Mr. STEELE. New 

 Edition. Crown Svo. cloth. loj. 6d. 



In this treatise will be found all the ordinary propositions, connected 

 with the Dynamics of Particles, which can be conveniently deduced 

 without the use of D' Alember? s Principle. Throughout the book 

 will be found a number of illustrative examples introduced in the 

 text, and for the most part completely vvorked out ; others with occa- 

 sional solutions or hints to assist the student are appended to each 

 chapter. For by far the greater portion of these, the Cambridge 

 Senate-House and College Examination Papers have been applied to.
