which he has treated the series of a real variable, the learner will owe him no 

 small debt of gratitude. 



We notice misprints on pages 141 and 278. 



The graph of y = cosec x on page 62 would be improved if the origin were in 

 the same relative position as that of its companion graph, y = sec x : and it should 

 be noted that the sides and angles of the pedal triangle of ABC are of different 

 forms according as ABC is an acute- or obtuse-angled triangle.

Problem Papers in Mathematics. By R. C. Fawdry. [Pp. viii + 240.] 

 (London : Macmillan & Co., Ltd., 1909. Price 4s. 6d.) 



Any teacher who has undertaken the preparation of candidates for army examina- 

 tions must have felt the difficulty of obtaining suitable examples to set to his pupils. 

 Whatever may be thought of the mathematics required for Sandhurst and 

 Woolwich, the fact remains that a distinct type of example is set, and that that 

 type is not to be found in the ordinary school text-books. Mr. Fawdry has done a 

 useful piece of work in compiling this book, which contains problems set to the 

 Military Side at Clifton during the past six years, as well as questions drawn from 

 other sources. The problems are arranged in graduated sets, and rise by easy stages 

 from arithmetic, algebra and geometry, through trigonometry, to mechanics, 

 analytical geometry and differential and integral calculus. Students preparing for 

 Mathematics I. or II. will find the book most useful : and we imagine that it will 

 be a great relief to teachers to have such a good store of examples ready to 

 hand. 



Revision papers, and a few papers from the examination for school certificates, 

 complete a book which should meet with a cordial reception.
