In effect, it may be declared emphatically that no one has a right to claim the exclusive merit of the brilliant discoveries of the past century. Science is essentially a collective work, prosecuted during the course of time by the efforts of a multitude of workers of every age and every nation, succeeding each other and associated in virtue of a tacit understanding for the research of truth in its purity, and for the application of this truth to the continual transformation of the condition of all men.
