Text -Books of Science. 



it is hoped that, while retaining the logical clearness and simple sequence 

 of thought which are essential to the making of a good scientific 

 treatise, the style and subject matter will be found to be within the 

 comprehension of working men, and suited to their wants. The books 

 will not be mere manuals for immediate application, nor University 

 text-books, in which mental training is the foremost object; they are 

 meant to be practical treatises, sound and exact in their logic, and with 

 evert/ theory and every process reduced to the stage of direct and useful 

 application, and illustrated by well-selected examples from familiar 

 processes and facts.
