Xll ADDRESS TO THE READER. 



farious occupations, can find leisure for rational recreation, 

 and mental improvement. Do not believe that the acqui- 

 sition of scientific knowledge will obstruct your worldly 

 prosperity, or that it is incompatible with your worldly 

 pursuits. Rely upon it, you cannot sharpen your intellec- 

 tual faculties, you cannot widen the range of your know- 

 ledge, without becoming more skilful and successful in the 

 business or profession in which you are engaged."* 



I may add, that by that happy connexion, whereby the 

 useful is indissolubly linked with the true, the exalted, and 

 the beautiful, science thus followed for its own sake, w T ill 

 pour forth abundant overflowing streams to enrich and 

 fertilize that industrial prosperity, which is the conquest of 

 the intelligence of Man over matter.f
