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 the father, or a coexistent disorder in the mother, 
may be a leading factor. A mechanical injury, such as a sudden fall, a 
blow, or a kick, or certain kinds of prolonged pressure, not to mention 
restrictions and contractions of the maternal bony structures, may all 
possibly contribute something to these prenatal miscarriages of growth 
and development. Maternal or prenatal embryonic infections could 
bring about many sorts of birthmarks and malformations. These defects 
might also be caused by certain types of severe inflammatory disorders 
in the uterus during the early days of pregnancy. 
The same factors that produce the accidents of embryology resulting in 
malformations or monstrosities in the human family, are also operative 
in the case of our lesser brethren of the animal kingdom, for 
monstrosities and birth-defects are very common among the lower 
animals, notwithstanding the fact that the animal mother probably does 
not "believe in birthmarks." 
"It is a striking fact that during the nineteenth century, the teratologists, 
those who have scientifically investigated the causes of monstrosities 
and fetal morbid states, have almost without exception, rejected the 
theory of maternal impressions." Scientists and physicians are coming 
to recognize the fact that fears and frights do not in any way act as 
causes in the production of monstrosities and deformities. Let us seek 
forever to liberate all womankind from the common and harassing fear 
and the definite dread and worry that, because they failed to control 
themselves at the instant of some terrifying sight or experience, they 
were directly responsible for the misfortune of their abnormal 
offspring. 
It should be remembered that there exists no direct connection 
whatsoever between the nervous system of the unborn child and the 
nervous system of the mother. The only physiological or embryological 
relationship is of a nutritional order, and even that is indirect and 
remote.
ROLE OF THE PLACENTA 
By the end of the third month, the "cocoon" attachment described in 
chapter two has disappeared; the fetus is slowly pushed away from the 
uterus which has so snugly held it for more than eleven weeks; while 
upon the exact site of its previous attachment the thickened uterine 
membrane undergoes a very interesting and important change--definite 
blood vessels begin to form--which begin indirectly to form contact 
with the maternal vessels, and thus it is that the placenta, or "after 
birth" is formed; and then, by means of the umbilical cord, nourishment 
from the mother's blood-stream is carried to the growing and rapidly 
developing child. In exchange for the nourishing stream of life-giving 
fluid by which growth and development take place, the embryo gives 
off its poisonous excretions which are carried back to the placenta, 
from which they are absorbed into the veinous circulation of the mother; 
so, while the mother does, through the process of nutrition, influence 
growth and development in the embryo, she is wholly unable to 
produce specific changes and such definite developmental errors as 
birthmarks and other deformities. 
Just as truly as it would be impossible so to frighten a setting hen as to 
"mark" or otherwise influence the form or character of the chicks which 
would ultimately come forth from the eggs in her nest, it is just as truly 
impossible to frighten the pregnant mother and thereby influence the 
final developmental product of the human egg which is so securely 
tucked away in its uterine nest; for, when conception has occurred, the 
human embryo is just as truly an egg--fashioned and formed--as is the 
larger and shell-contained embryo of the chick which lies in the nest of 
the setting hen. 
And so we are compelled to recognize the fact that there is little more 
danger to the unborn child when the mother is frightened than when the 
father is scared. The one contributes as much as the other to the general 
character of the child, while neither is to blame for development errors 
and defects.
