PREFACE.

To exhibit the scope and tendency of the present Treatise we need only insert here the PROSPECTUSs which has been some time before the public:

"Each volume of the Scientific Library proposes to develop the Elements of a Science, or Sciences, in a brief, systematic, demonstrative form, so that the entire Series may supply a body of Mathematical and Physical Knowledge complete, but in nothing superfluous. This Series will exhibit the abstract beauty and utility of Science, which it would not be judicious to impair by irrelevant matters. But there is likewise a practical beauty and utility in Science, which should be brought home to men's business and bosoms. To accomplish this we design publishing a Set of Companions to the Sciences, in which the abstract principles already developed in our first Series will be applied to practice, exemplifying their value in improving the worldly condition of man, as well as his intellectual. By means of this Companion Library we shall be enabled at once to confirm its readers in the Elements of our first Series, to instruct them in the method of drawing practical benefit from their acquired knowledge, and to furnish a ready answer to the often-repeated inquiryWhat is the use of abstract Science?"
