[24]: "Know ye not that ye are the temple of God, and that the spirit of God dwelleth in you?" 1 Cor. 3. xvi. [25]: Dr. Drysdale, in his work on the "Protoplasmic Theory of Life," says: "Matter cannot change its state of motion or rest without the influence of some force from without. True spontaneity of movement is, therefore, just as impossible to it as to what we call dead matter.... So we are compelled to admit the existence of an exciting cause in the form of some force from without to give the initial impulse in all vital actions." In all life-manifestations, this "force from without," must be a pre-existing vital principle operating to effect the otherwise impossible change in matter. [26]: A favorite set-phrase of Professor Bastian in speaking of morphological cells or "units," as he sometimes calls them. [27]: That great and justly celebrated naturalist, Buffon, in speaking of the universal origination of the lower forms of animal life by a process termed, in his time, "spontaneous generation," says: "There are, perhaps, as many living things, both animal and vegetable, which are produced by the fortuitous aggregations of 'molécules organiques,' as there are others which reproduce themselves by a constant succession of generations." It is said that Buffon was for some time associated with the Abbé Needham in his experiments in vital directions, and was much influenced by them. So that it is by no means certain that he did not accept the Abbé's "force végétative" in place of his more materialistic views respecting "molécules organiques." At all events, his statement that as many living things appear in nature independently of reproducing causes as by successive generation, is no doubt true. [28]: M. Tréviranus, who followed Spallanzani and M. Bonnet in these flask experimentations, first noticed the important fact that the animalculæ appearing in different organic infusions, depended on the nature and quality of the infusions themselves, and that the changed conditions of the same infusion produced new and independent forms of life.
