Rittinger's theory and law of the energy expended in crushing of rock is that the work of crushing is proportional to the reduction in diameter; or, as I have more fully expressed it: "The work done in crushing is proportional to the surface exposed by the operation; or, better expressed for this purpose, the work done on a given mass of rock is proportional to the reciprocal of the ...

I happen to be one of those who believe that Rittinger probably meant what he said when he wrote what Stadler has quoted, "the increase of the surfaces exposed is directly proportional to the force required for reducing" "and therefore also to the work absorbed in effecting the separa­tions." (The italics are now mine instead of Rittinger's or Stadler's.)
