May we not suppose that masses of it were produced during the incandescence of the earth, and that, when the waters descended, they passed through a series of changes which culminated in living plasm? Such is the "cyanogen hypothesis" of the origin of life, advocated by able physiologists such as Pfluger, Verworn, and others.

Verworn attacks it at the lowest level, and attempts to solve it by reference to the surface tension to which all fluid bodies are subject, and to the partial relaxation of this, which forces the mass to give off radiating processes orpseudopodia.” The mechanical causes of the suspension of the surface tension are inquired into, and striking examples of pseudopod-like rays are found in the inorganic world, for instance, in a drop of oil.

We see matter all about us, acted upon by the mechanico-chemical forces, that never takes on any of the distinctive phenomena of living bodies. Yet Verworn is convinced that if we could bring the elements of a living body together as Nature does, in the same order and proportion, and combine them in the selfsame way, or bring about the vital conditions, a living being would result. Undoubtedly.

The most recent of these hypotheses is that set forth by Verworn in his bookDie Biogenhypothese.” He assumes, as the central vehicle of the vital functions, a unified living substance, thebiogen,” nearly related to the proteids which form the fundamental substance of protoplasm and of the cell-nucleus, and in contrast to which the other substances found in the living body are in part raw materials and reserves, and in part of a derivative nature, or the results of disruptive metabolism.

Professor Moore, of Liverpool University, as I have already pointed out while discussing the term "vital force," invents a new phrase, "biotic energy," to explain the same phenomena. Surely a force by any other name is no more and no less potent. Both Verworn and Moore feel the need, as we all do, of some term, or terms, by which to explain that activity in matter which we call vital.

It grasps the particle of sand by the feeler, and passes it into its body by enclosing it. Verworn removed the sand from the bottom of the tank, replacing it by very minute particles of highly colored glass. Shortly afterward he noticed a collection of these particles of glass in the body of the creature, and a little later he saw a tiny speck of protoplasm emitted from the parent by separation.
