But the chief question before us is, whether it is quite certain that, from the time of that which is called the Azoic Age, there ever was such an atmosphere as that hypothesized by the Naturalists. Not all the Physicists agree with this idea. Were the writer anxious to corroborate the teachings of the Secret Doctrine by exact Science, it would be easy to show, on the admission of more than one Physicist, that the atmosphere has changed little, if at all, since the first condensation of the oceans—_i.e._, since the Laurentian Period, the Pyrolithic Age. Such, at any rate, is the opinion of Blanchard, S. Meunier, and even of Bischof—as the experiments of the last Scientist with basalts have shown. For were we to take the word of the majority of Scientists as to the quantity of deadly gases, and of elements entirely saturated with Carbon and Nitrogen, in which the vegetable and animal kingdoms are shown to have lived, thriven, and developed, then one would have to come to the curious conclusion that there were, in those days, oceans of _liquid carbonic acid_, instead of water. With such an element, it becomes doubtful whether the Ganoids, or even the Primitive Trilobites themselves could live in the oceans of the Primary Age—let alone in those of the Silurian, as shown by Blanchard. The conditions that were necessary for the earliest Race of mankind, however, require no elements, whether simple or compound. That which was stated at the beginning is maintained. The spiritual ethereal Entity which lived in Spaces unknown to Earth, before the first sidereal “jelly‐speck” evolved in the Ocean of crude Cosmic Matter—billions and trillions of years before our globular speck in infinity, called Earth, came into being and generated the Monera in its drops, called oceans—needed no “elements.” The “Manu with soft bones,” could well dispense with Calcium Phosphate, as he had no bones, save in a figurative sense. And while even the Monera, however homogeneous their organism, still required physical conditions of life that would help them toward further evolution, the Being which became Primitive Man and the “Father of Man,” after evolving on planes of existence undreamed of by Science, could well remain impervious to any state of atmospheric conditions around him. The primitive ancestor, in Brasseur de Bourbourg’s _Popol Vuh_, who—in the Mexican legends—could act and live with equal ease under ground and water as upon the earth, answers only to the Second and early Third Races in our texts. And if the three kingdoms of Nature were so different in pre‐diluvian ages, why should not man have been composed of materials and combinations of atoms now entirely unknown to Physical Science? The plants and animals now known, in almost numberless varieties and species, have all developed, according to scientific hypotheses, from primitive and far fewer organic forms. Why should not the same have occurred in the case of man, the elements, and
