%* The Authors were induced to undertake the task of producing a series of Scientific Manuals. 

 by the consideration that as there existed no medium between the abstruse and voluminous work* 

 adapted to the wants of the advanced Student, and the so-called popular scientific treatises of 

 the day, many intelligent and well-educated persons were compelled, in the pursuit of knowledge, 

 to rest satisfied with loose and inaccurate statements on scientific subjects. Their object was to 

 supply this class of readers with brief but thoroughly scientific compendiums which should in- 

 clude" every question of practical value, and at the same time require no further knowledge of 

 Mathematics than that possessed by a person well instructed in elementary Algebra and Trigo- 

 nometry. As a valuable aid to both Teacher and Learner, they have illustrated every question 

 treated in their Manuals by copious and well-selected examples of a thoroughly practical character. 



The great success which these Manuals have already obtained in England is a sufficient proof 

 that the Authors have accomplished their object. In future Editions they hope, by the aid of 

 their own experience as Teachers, and the valuable suggestions they have received, to render 

 their Manuals a valuable adjunct to education in all the first-elass Schools of England. 



This Series is now placed on the List of Books recommended by the Committee 

 of Privy Council for Fducation.
