ABSTRACT
Newton himself phrased it in his Opticks [2-7], was the inherent tendency for the emanation to reunite with the parent body. Ultimately, the corpuscular theory of light, as espoused in a tentative way by Newton and his followers, particularly Wilhelm Jacob 'sGravesande, came to be seen as a model of emissions too rare and subtle to cause perceptible loss of weight, and the doctrine of the retum of effluvia was dropped [2-8].
