The heavy metals, once organic elements, no longer melted, and did not return into the circulation from which they had been cast out. They are the signs of the rigor mortis of the gigantic, cooling, primaeval organisms, whose breath perchance was luminous iron-vapour, whose blood was liquid metal, and whose food was meteorites." 4. Pfliiger's Idea In one of the most suggestive works in physiological literature Pfliiger ('75,1) has discussed very fully the question of the origin of life upon the earth, and has defended the idea of spontaneous generation, that living substance originated upon the earth itself out of lifeless substances. Pfliiger's ideas are especially valuable in that in a strictly scientific manner he discusses the problem in intimate connection with the facts of physiological chemistry, and follows it out far into detail. The essential point of Pfliiger's investigation is constituted by the chemical characteristics of proteid as that substance with which life in its essentials is inseparably united. There exists a fundamental difference between dead proteid, as it occurs, e.g., in egg-albumin, and living proteid, as it constitutes living substance: this difference is the self-decomposition of the latter. All living substance is continually being decomposed, in some degree spontaneously and more through outside influences, while dead proteid under favourable conditions remains intact for an unlimited time. The chief condition of this decomposition is intramolecular oxygen, i.e., the oxygen that occurs in the living proteid molecule, and is continually being received by it from the outside through respiration. That this oxygen is the essential condition follows from the facts that during the decomposition...
