“Worlds without number
Lie in this bosom like children.”
While unanimously agreeing that physical causes, such as blows, accidents, and bad quality of food for the mother, effect the fœtus in a way which endangers its life; and while admitting again that moral causes, such as fear, sudden terror, violent grief, or even extreme joy, may retard the growth of the fœtus or even kill it, many physiologists agree with Magendie in saying, “there is no reason for believing that the imagination of the mother can have any influence in the formation of monsters;” and only because “productions of this kind are daily observed in the production of other animals and even in plants.”
In this opinion he is supported by the leading teratologists of our day. Although Geoffroi St. Hilaire gave its name to the new science, its facts are based upon the exhaustive experiments of Bichat, who, in 1802, was recognized as the founder of analytical and philosophical anatomy. One of the most important contributions to teratological literature is the monograph of G. J. Fisher, M. D., of Sing Sing, N. Y., entitled Diploteratology; an Essay on Compound Human Monsters. This writer classifies monstrous fœtal growths into their genera and species, accompanying the cases with reflections suggested by their peculiarities. Following St. Hilaire, he divides the history of the subject into the fabulous, the positive, and the scientific periods.
It suffices for our purpose to say that in the present state of scientific opinion two points are considered as established: 1, that the maternal, mental condition has no influence in the production of monstrosities; 2, that most varieties of monstrosity may be accounted for on the theory of arrest and retardation of development. Says Fisher, “By a careful study of the laws of development and the order in which the various organs are evolved in the embryo, it has been observed that monsters by defect or arrest of development, are, to a certain extent, permanent embryos. The abnormal organs merely represent the primitive condition of formation as it existed in an early stage of embryonic or fœtal life.”[621]
With physiology in so confessedly chaotic a state as it is at present, it seems a little like hardihood in any teratologist, however great his achievements in anatomy, histology, or embryology, to take so dangerous a position as that the mother has no influence upon her offspring. While the microscopes of Haller and Prolik, Dareste and Laraboulet have disclosed to us many interesting facts concerning the single or double primitive traces on the vitelline membrane, what remains undiscovered about embryology by modern science appears greater still. If we grant that monstrosities are the result of an arrest of development—nay, if we go farther, and concede that the fœtal future may be prognosticated from the vitelline tracings, where will the teratologists take us to learn the antecedent psychological cause of either? Dr. Fisher may have carefully studied some hundreds of cases, and feel himself authorized to construct a new classification of their genera and species; but facts are facts, and outside the field of his observation it appears, even if we judge but by our own personal experience, in various countries, that there are abundant attainable proofs that the violent maternal emotions are often reflected in tangible, visible, and permanent disfigurements of the child. And the cases in question seem, moreover, to contradict Dr. Fisher’s assertion that monstrous growths are due to causes traceable to “the early stages of embryonic or fœtal life.” One case was that of a Judge of an Imperial Court at Saratow, Russia, who always wore a bandage to cover a mouse-mark on the left side of his face. It was a perfectly-formed mouse, whose body was represented in high relief upon the cheek, and the tail ran upward across the temple and was lost in his hair. The body seemed glossy, gray, and quite natural. According to his own account, his mother had an unconquerable repugnance to mice, and her labor was prematurely brought on by seeing a mouse jump out from her workbox.
In another instance, of which the writer was a witness, a pregnant lady, within two or three weeks of her accouchement, saw a bowl of raspberries, and was seized with an irresistible longing for some, but denied. She excitedly clasped her right hand to her neck in a somewhat theatrical manner, and exclaimed that she must have them. The child born under our eyes, three weeks later, had a perfectly-defined raspberry on the right side of his neck; to this day, when that fruit ripens, his birth-mark becomes of a deep crimson, while, during the winter, it is quite pale.
Such cases as these, which are familiar to many mothers of families, either in their personal experience or that of friends, carry conviction, despite the theories of all the teratologists of Europe and America. Because, forsooth, animals and plants are observed to produce malformations of their species as well as human beings, Magendie and his school infer that the human malformations of an identical character are not at all due to maternal imagination, since the former are not. If physical causes produce physical effects in the subordinate kingdoms, the inference is that the same rule must hold with ourselves.
But an entirely original theory was broached by Professor Armor, of the Long Island Medical College, in the course of a discussion recently held in the Detroit Academy of Medicine. In opposition to the orthodox views which Dr. Fisher represents, Professor Armor says that malformations result from either one of two causes—1, a deficiency or abnormal condition in the generative matter from which the fœtus is developed, or 2, morbid influences acting on the fœtus in utero. He maintains that the generative matter represents in its composition every tissue, structure, and form, and that there may be such a transmission of acquired structural peculiarities as would make the generative matter incapable of producing a healthy and equally-developed offspring. On the other hand, the generative matter may be perfect in itself, but being subjected to morbid influences during the process of gestation, the offspring will, of necessity, be monstrous.
To be consistent, this theory must account for diploteratological cases (double-headed or double-membered monsters), which seems difficult. We might, perhaps, admit that in defective generative matter, the head of the embryo might not be represented, or any other part of the body be deficient; but, it hardly seems as if there could be two, three, or more representatives of a single member. Again, if the generative matter have hereditary taint, it seems as if all the resulting progeny should be equally monstrous; whereas the fact is that in many cases the mother has given birth to a number of healthy children before the monster made its appearance, all being the progeny of one father. Numerous cases of this kind are quoted by Dr. Fisher; among others he cites the case of Catherine Corcoran,[622] a “very healthy woman, thirty years of age and who, previously to giving birth to this monster had born five well-formed children, no two of which were twins ... it had a head at either extremity, two chests, with arms complete, two abdominal and two pelvic cavities united end to end, with four legs placed two at either side, where the union between the two occurred.” Certain parts of the body, however, were not duplicated, and therefore this cannot be claimed as a case of the growing together of twins.
