HEALTH AND THE LAWS OF MECHANICS 123 



All forces are correlative harmonic rhythmic 

 vibrations, which are mutually transformed into 

 simple relations in the numeric series expressive 

 of universal harmony. 



Sound, light, heat, electricity, mechanical work, 

 chemical affinity, constitute forms of universal 

 energy equivalent to one another, and can, in the 

 majority of cases, be weighed and measured. 



We can study in special treatises the mechanical 

 equivalents of heat, of work, of chemical reaction ; 

 and though the series is not complete, ever ex- 

 tending with new discoveries, it is none the 

 less certain that man has been enabled to fix 

 the definite proportions of the majority of these 

 rhythms. 



The law of gravity continually attracts matter in 

 direct ratio to its mass, and inversely as the square 

 of the distance. 



For the so-called chemical forces, Lavoisier dis- 

 covered the simple numeric relation formulated in 

 his law : The weight of any combined bodies is equal 

 to the sum of the weights of their components. 



No less simple is Dalton's law of multiple 

 proportions : Whenever two elements are combined 

 in variable ponderable quantities, if we take as a 

 fixed quantity that of one of them, that of the other 

 then becoming variable, the quantities of the varying 

 body are multiples or submultiples of the others.
