but each of his children come into the world without the slightest knowledge of the subject, and, as far as direct and immediate heredity is concerned, will have to work just about as hard to master the subject as will the same average class of children whose parents were not surgeons. This must not be taken to mean that certain abilities and tendencies are not inheritable--for they are; but they are inherited through the parents--and not from them--directly. These transmitted characteristics are largely "stock" traits, and usually have long been present in the "ancestral strain."
MATERNAL IMPRESSIONS
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.
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.
Such unscientific and unwarranted teaching has been handed down from mother to daughter through the ages, while the poor, misguided souls of expectant women have suffered untold remorse, heaped blame upon themselves, lived lives literally cursed with fear and dread--veritable slaves to superstition and bondage--all because of the simple fact that a certain percentage of all children born in this world have sustained some sort of an injury or "embryological accident" during the first days of fetal existence. For instance, take the common birthmark of a patch of reddened skin on the face, brow, or neck. As soon as the baby is born, the worried mother asks in anxious tones: "Doctor, is it all right, is it perfect, has it got any birthmarks?" On being told that the baby has a round, red patch on its left brow, the ever-ready statement of the mother comes forth: "Yes, I knew I'd mark it, I was picking berries one day about three months ago, and I ate and ate, until I suddenly remembered I might mark my baby, and before I knew what I was doing, I touched my brow and I just knew I had marked my baby." Do you know, reader, that that birthmark was present fully four months before she passed through that experience in the berry patch? And yet so worried and apprehensive has been the pregnant mother, that, although she can never successfully predict the "birthmarks" and blemishes of her child, nevertheless when these defects are disclosed at birth she is unfailingly able immediately to recall some extraordinary experience which she has carefully stored away in her memory and which, to her mind, most fully explains and accounts for the defect.
Is it much wonder that in the very early days of embryonic existence, during the hours of delicate cell division, indentation, outpushing, elongation, and sliding of young cells--is it much wonder, I repeat--that there occur a few malformations, blemishes, or other accidents which persist as "birthmarks?"
CAUSES OF BIRTHMARKS
There are many factors which may enter into the production of birth-blemishes, deformities, monstrosities, etc. These influences are all governed by certain definite laws of cause and effect. A pre-existent systemic disease in
