Intellect, memory and will-power are necessary to produce two or more forces and motions in a prescribed order and within a given time. For example, each note in a piece of music requires, for its production, a certain force and peculiar motion (vibration) of cord, pipe or string within a certain time. It is obvious that intellect, memory and will-power are necessary to sing or play any piece of music. Before anyone can speak any given word he must have intellect, memory and will-power: (1) he must know the word to be uttered, (2) he must remember it until it is uttered, (3) he must have the will-power necessary to exert the force and produce the motion of air necessary to utter it. Let the reader speak the words: “earth,” “air,” “fire,” “water,” and analyze the process. Intellect, memory and will-power are necessary to generate, guide, and control the forces and motions required to make a watch or any other compound machine or structure, within a given time. Suppose that a watchmaker is required to make each spring, wheel and part of a watch by hand, to put every part in its place and start it to running on or about the 280th day after he begins the work. (Haeckel Ev. Man, p. 199.) To do this work he must have intellect, memory and will-power to generate, guide, and control and time the forces and motions which are necessary to make each part of the watch and to fit and group them together when completed. He must know and remember every part of it; remember the material of which it is made; remember its form and size; compare each piece with the pattern; remember the time in which he is to do the work. He must have the will-power to begin and continue the work until it is done, doing such part of it each day as to complete it on or about the day fixed. But the forces and motions, which build up the body of the embryo, work in the dark without brain or sense-organs. To put the watchmaker on the same basis with the Creator, we will have to suppose that the watchmaker is blind and has no sense of touch. Would it be possible for him to make a watch under these conditions? The mother’s food is taken into her mouth, chewed and mixed with saliva and passes into her stomach. Here it is mixed with gastric juice and converted into chyme. It then passes into the small intestine (duodenum) where it is mixed with pancreatic secretion, bile and “the secretion of the glands Brunner and the Crypts of Lieberkühn” and thus converted into chyle. Most of the “nutritive constituents” of the chyle pass through the epithelium of the small intestines into the subjacent blood and lymphatic vessels and are carried off. Those passing into the blood capillaries are taken by the portal vein to the liver; while those entering the lacteals are carried into the left jugular vein by the thoracic duct.
