A mother may sing and pray all through the nine months of expectancy, or she may weep and scold, or even curse. In neither case can she influence the spiritual or moral tendencies of her child and cause it, through supposed prenatal influence, to be born with criminal tendencies or to grow up a pious lad or become a devout minister. These tendencies and characteristics are all largely determined by the "depressors," "suppressors," and "determiners" which were present in the two microscopic and mosaic germ cells which united to start the embryo at the time of conception.

The child is destined to be born, endowed, and equipped with the mental, nervous, and physical powers which his line has fallen heir to all through the past ages. Down through the ages education, religion, environment, and other special influences have no doubt played a small part in influencing and determining hereditary characteristics; just as environment in the ages past changed the foot of the evolving horse from a flat, "cushiony" foot with many toes (much needed in the soft bog of his earlier existence) into the "hoof foot" of later days, when harder soil and necessity for greater fleetness, assisted by some sort of "selection" and "survival," conspired to give us the foot of our modern horse, and this story is all plainly and serially told in the fossil and other remains found in our own hemisphere. It would appear that many, many generations of education and environment are required to influence markedly the established and settled train of heredity regarding any particular element or characteristic in any particular line or lines of hereditary tendencies.
