The objection that all these actions are merely reflex-actions does not detract an iota from the marvel. Then the coördination of all these reflexes is miraculous. It only changes the name of instinct into reflex, just as the change of the name of the creative power from the old name of God into that of the atheist’s “Nature,” or of Plato’s “idea,” or Nietzsche’s “Wille zur Macht,” or Bergson’s “Élan vital,” or Shaw’s “Life force,” etc., does not in the least change the nature of the creative power. [U] Hegar says that in civilized men we can not speak at all of an instinct of propagation. For with them so many reflexions and considerations enter into play that to speak of anything impulsive is to ignore the state of mind of the society of our days. [V] The old German law punished adultery or granted a divorce only when intermissio penis in vaginam has been witnessed. [W] M. Maupus (Archives de Zoologie expérimentelle, 1889) has shown that without conjugation, the members of an isolated family of infusoria eventually cease to feed and divide and pass through the stages of degeneration and senility to extinction. (In the train of conjugation there is always death. Non-conjugating protozoa are immortal. Eve and Death.) [X] Colonies arise when the individual animals do not leave each other, after their division, to live a separate life but remain together. After the second division there are four animals or members, after the third division eight, then sixteen, thirty-two, etc., until an entire colony of millions of cells has risen. The human body is composed of some twenty-six trillions of cells (26,000,000,000,000,000,000). Brain and spinal cord alone contain two billion cells. [Y] It must be quite a shock to the prude, in the knowledge that the much admired flower represents in its ensemble the sex-organs of the plants, or those parts which in men possess for the sensualist a peculiar aesthetic attraction. Most perfumes, so generally used by the sensual, are extracts from flowers, i. e., the sexual parts of the plants; some perfumes are taken even from the sexual organs of the animal, e. g., musk. This fact may account for the exaggerated love of the sensualists for flowers and perfumes. [Z] Weissman believes that in each individual, produced by sexual generation, a portion of germ-plasm, derived from both parents, is not employed in the construction of the cells and tissues of the soma, or personal structure of the individual, but is set aside, without change, for the formation of the germ-cells of the succeeding generation. According to Boveri, the ovum has all the organs and qualities necessary for the development of the foetus, except that its centrosome, which starts segmentation, is in a state of inactivity, while the spermatozoön possesses the active centrosome but lacks the protoplasma or the material by means of which this organ could begin its activity.
