The earliest forms of Life, the unicellular "Beings," whether animal or vegetable--for both divisions, if they can be said to be divided, have the same protoplasmic cell as basis of life--were, and are still, immortal except for accidents; they are not subject to natural death as we know it; they multiply by fission and not by "budding." It was only with the building up of cell upon cell into communities, and the advent of polycellular beings of greater and greater complexity of structure, that the "Wisdom" behind natural laws introduced death as an _adaptation_, to prevent monstrosities in the shape of mutilated specimens being perpetuated on the earth. Life is purely physical and, in conformity with the modes under which our physical senses act, has the appearance of tri-unity. As white light is seen to be composed of but three primary colours, as Music is based on the Triad, as Space is known to us in three dimensions only, and Geometry, "the Head of all Learning," is based upon the Circle, Square, and Triangle, so may we see life in its three primary aspects: the Animal, Vegetable, and Material. The last-mentioned aspect, though long suspected, from the investigation of Crystallography, to have in some mysterious way a common basis with the animal and vegetable, was not fully grasped until, in the last few years, we have been able to study in our laboratories the actual evolution, or more correctly devolution, of matter from one form to another; and as all plants and animals are found to be built up of the same identical protoplasmic cells, so are we now able to break down and analyse not only these cells but even the very structure of matter, and find that all substances are built up of exactly the same bricks, the different forms known to us as Elements being the _designs_ of the great Architect upon which each structure has been built; and these completed designs again are used and become the "ashlars" of the higher forms of plant and animal structure. As Evolution in the Animal and Vegetable Kingdoms has given us Species, so in the Material it has developed Elements. The structures of animal and vegetable life are of comparatively recent formation, and are still apparently progressing in the direction of complexity, whereas the structures of matter appear to have long passed the stage of highest complexity, and the elements are now undergoing the retrograde process of being transformed, by radio-activity, from the more complex into simpler elements of lower atomic denominations--namely, having fewer bricks in each atom.
