Many of the cases given as examples, and by physicians too, are so ridiculous that no scientific man can give them the slightest credence for one moment. When a physician (Dr. Thomas J. Savage) tells us that he attended a lady who had been frightened by a large green frog at or about the middle of pregnancy, and that she gave birth to a monstrosity, the head of which was that of a large frog in shape, with the eyes and mouth and even the coloring of a frog, then he is either telling an untruth, or he shows himself as ignorant and credulous as any illiterate old woman can be. The doctor should know that at the middle of pregnancy the child is _fully formed_ and that there is no possibility of an already formed human being changing its shape into that of an animal. Another example given by the same doctor, and showing the calibre of his mentality, is that of a child which, when an infant, not old enough to walk, "would crawl over the floor and pick up little objects such as pins, tacks, small beads, without the slightest difficulty or fumbling." The reason for this "remarkable" skill the good doctor ascribes to the fact that four months before the birth of this child the mother had an outing in the woods and had derived great enjoyment from gathering hickory nuts which she found scattered among the leaves with which the ground was thickly covered! Very often the so-called shock or fright which the mother experiences during gestation is simply a product of her imagination. We know of many cases where the mothers never mentioned that anything happened to them, and only after the child was born with some kind of mark or defect they began to hunt for causes and claimed that such and such a thing happened to them while they were pregnant, but on close investigation the alleged event was found to have originated in the mother's brain. In short, while the subject of maternal impressions is an interesting one and demands further investigation, there is at the present time no scientific justification for the belief in maternal impressions. Particularly must we scout any stories of maternal impressions during the latter part of pregnancy, during the fifth, sixth, seventh, eighth, or ninth month. Because after the child is fully formed no mental or psychic impressions can make birthmarks on it, amputate its limbs, or convert it into any sort of monstrosity. After the above was written and ready for the printer I came across four cases of alleged maternal impressions in a book by Laura A. Calhoun ("Sex Determination and Its Practical Application"). The first three cases the author relates without any comment, taking them evidently for pure coin. The fourth case the lady investigated, and she is frank to say that what seemed at first as a clear case of maternal impression was nothing of the kind but merely a case of heredity. In order to break the monotony for a little while I will reproduce here the four cases in the lady's own words.
