88 THE ANATOMY OF SCIENCE 



recourse to the concept of mass or to the laws 

 of mechanics. The two sciences do, however, 

 overlap here and there, and their interrelation- 

 ships have suggested certain mechanical theo- 

 ries of electricity and magnetism which, if the 

 order of development of the two sciences had 

 been changed, would more frequently have ap- 

 peared as electromagnetic theories of mechan- 

 ics. 



In proceeding from geometry through kine- 

 matics to either of these larger sciences we are 

 getting farther away both from the formality 

 of mathematics and from everyday experience; 

 we depend more upon evidence furnished by 

 new observations and by experiments with more 

 or less elaborate apparatus. Yet the transition 

 is a gradual one, and the remarkable develop- 

 ments in mechanics and electromagnetics which 

 are now going on promise to reduce these two 

 sciences to a more comprehensive but also a 

 more difficult geometry. 



In introducing the science of mechanics, we 

 may dwell for a moment upon the earlier devel- 

 opment of the principles of statics, which is so 

 admirably set before us in the beautiful treatise 

 of Mach.^ When Archimedes presented his dis-
