hope from this book alone to study and understand the very large number of 

 problems that are dealt with unless he has had a good technical and mathematical 

 training. Thus the intimation in the preface as to the amount of mathematics 

 required appears to be misleading, and there are very few students who could 

 understand the differential and integral calculus from the few remarks given in 

 the first chapter. In fact, this chapter is only to be justified by the point of view 

 of reference. To take another instance, the whirling of shafts, which is really a 

 difficult subject, should at least contain a reference to Prof. Dunkerley's original 

 investigations in the Phil. Trans, to enable the student to understand the subject 

 properly, since there are variations in whirling which are dealt wich in that paper 

 .vhich might easily be called for by an examiner as well as the simple cases 

 given by the writer. Aided by the instruction of a good teacher, who can ref~r 

 the student to other books for further information on subjects such as the Ellipse 

 of Stress and various other problems, the book might be safely recommended to 

 students of engineering.
