ALPHABETS OP THE SCIENCES. 



FOR THE USE OF SCHOOLS A^ 7 D SELF-INSTRUCTION. 



This series of little Volumes was undertaken with the design of furnishing 

 young learners with plain, easy, short, and cheap introductions to the different 

 sciences, at the same time making them more substantial and trust-worthy in 

 fact and inference than has been usually done in introductory works. To attain 

 this object, it was necessary to exclude every unimportant detail, and to con- 

 dense into as small a compass as possible the valuable materials which had hi- 

 therto remained scattered through many volumes both British and Foreign. In 

 preparing these little volumes for the press, the aim of the Editor, and those 

 Gentlemen who have assisted him, has not been directed so much to originality 

 of information, as to present a fair epitome of the present state of knowledge 

 in the branches of science treated of, and a detail of such facts as seemed to bear 

 more immediately upon the principles of the science ; it has been laid down as 

 a rule to admit no technical terms in the text without a plain and intelligible 

 explanation of them, either as a foot-note or otherwise. This plan has been 

 strictly adhered to throughout the Series, and these little volumes will be found 

 highly useful both in schools and to those who wish to acquire the principles of 

 a science without the aid of a teacher.
