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. EUGENIC SUPERSTITION There is probably more misinformation in the minds of the people on the subject of "maternal impressions" and "birthmarks" than any other scientific or medical subject. The popular belief that, if a pregnant woman should see an ugly sight or pass through some terrifying experience, in some mysterious way her unborn child would be "marked," deformed, or in some way show some blemish at birth, is a time-honored and ancient belief.
