We will not go into the very complicated details of the actual process of the growth and division of the protoplasmic cells. It is enough to say that in the case of living creatures provided with more complicated organisms, such as the higher plants, animals and man, the little cell units divide and grow as they do in the case of the lower organisms. The fact is one which shows the intimate inner relationship of all living beings. THE LADDER OF ORGANIC ASCENT As we mount the ascending ladder of plant and animal life the unit-cell of the lower organisms is replaced by a great number of individual cells, which have grown together to form a completed whole. In this complete whole the cells, in accordance with the specific purpose for which they are intended, all have a different form and a different chemical composition. Thus it is that in the case of the plants leaves, flowers, buds, bark, branches and stems are formed, and in that of animals skin, intestines, glands, blood, muscles, nerves, brain and the organs of sense. In spite of the complicated nature of numerous organisms we find that many of them still possess the power of reproducing themselves by division or a process of "budding." In the case of certain plants and animals, cell-groups grow together into a so-called "bud," which later detaches itself from the parent body and forms a new individual living organism, as in the case of the polyps or the tubers in plant life. A tree, for instance, may be grown from a graft which has been cut off and planted in the ground. And ants and bees which have not been fecundated are quite capable of laying eggs out of which develop perfect, well-formed descendants. This last process is called parthenogenesis. It is a process, however, which if carried on through several generations, ends in deterioration and degeneracy. In the case of the higher animals, vertebrates and man, such reproduction is an impossibility. These higher types of animal life have been provided by nature with special organs of reproduction and reproductive glands whose secretions, when they are projected from the body under certain conditions, reproduce themselves, and increase and develop in such wise that the living organism from which they proceed is reproduced in practically its identical form. Thus it perpetuates the original type. Philosophically it may be said that these cells directly continue the life of the parents, so that death in reality only destroys a part of the individual. Every individual lives again in his offspring. THE TRUE MISSION OF SEX
