mporaneous incre-ments of y, i. e. the dys. But in this case the dysare all equal. Hence there being no difference be-tween two successive states of dy, as between PEand PE, there is no successive differential, or the differential of dy is 0, since dy is constant. This fact appears also from the… … Fig. 16. whose equation is y^ 2px ; whence dy =^—. Still con-
