But, as far as I know, this is the only instance of this observation on record. Herbert Spencer has shown that when a pure-bred animal breeds with an animal of a mixed breed, the offspring resembles much more closely the parent of pure blood, and this may explain why the circumstance recorded by Balfour has been so seldom noted. For a negro, who is of very pure blood, will naturally have a stronger influence on the subsequent progeny than an Anglo-Saxon, who comes of a mixed stock. If this be the correct explanation, we should expect that when a white woman married first a black man, and then a white, the children by the white husband would be dark colored. Unfortunately for the proof of telegony, it is very rare that a white woman does marry a black man, and then have a white as second husband;nevertheless, we have a fair number of recorded instances of dark-colored children being born in the above way of white parents.
"Dr. Harvey mentions a case in which 'a young woman, residing in Edinburgh, and born of white (Scottish) parents, but whose mother, some time previous to her marriage, had a natural (mulatto) child by a negro man-servant in Edinburgh, exhibits distinct traces of the negro. Dr. Simpson --afterward Sir James Simpson--whose patient the young woman at one time was, has had no recent opportunities of satisfying himself as to the precise extent to which the negro character prevails in her features; but he recollects being struck with the resemblance, and noticed particularly that the hair had the qualities characteristic of the negro.' Herbert Spencer got a letter from a 'distinguished correspondent' in the United States, who said that children by white parents had been 'repeatedly' observed to show traces of black blood when the women had had previous connection with (i.e., a child by) a negro. Dr. Youmans of New York interviewed several medical professors, who said the above was 'generally accepted as a fact.' Prof. Austin Flint, in 'A Text-book of Human Physiology,' mentioned this fact, and when asked about it said:
'He had never heard the statement questioned.'
"But it is not only in relation to color that we find telegony to have been noticed in the human subject. Dr. Middleton Michel gives a most interesting case in the American Journal of the Medical Sciences for 1868: 'A black woman, mother of several negro children, none of whom were deformed in any particular, had illicit intercourse with a white man, by whom she became pregnant. During gestation she manifested great uneasiness of mind, lest the birth of a mulatto offspring should disclose her conduct. . . . It so happened that her negro husband possessed a sixth digit on each hand, but there was no peculiarity of any kind in the white man, yet when the mulatto child was born it actually presented the deformity of a supernumerary finger.'
Taruffi, the celebrated Italian teratologist, in speaking of the subject, says: 'Our knowledge of this strange fact is by no means recent for Fienus, in 1608, said that most of the children born in *****ery have a greater resemblance to the legal than to the real father'--an observation that was confirmed by the philosopher Vanini and by the naturalist Ambrosini. From these observations comes the proverb: 'Filium ex *****era excusare matrem a culpa.' Osiander has noted telegony in relation to moral qualities of children by a second marriage. Harvey said that it has long been known that the children by a second husband resemble the first husband in features mind, and disposition. He then gave a case in which this resemblance was very well marked.
Orton, Burdach (Traite de Physiologie), and Dr. William Sedgwick have all remarked on this physical resemblance; and Dr. Metcalfe, in a dissertation delivered before this society in 1855, observed that in the cases of widows remarrying the children of the second marriage frequently resemble the first husband.
"An observation probably having some bearing on this subject was made by Count de Stuzeleci (Harvey, loc. cit.). He noticed that when an aboriginal female had had a child by a European, she lost the power of conception by a male of her own race, but could produce children by a white man. He believed this to be the case with many aboriginal races; but it has been disproved, or at all events proved to be by no means a universal law, in every case except that of the aborigines of Australia and New Zealand. Dr.
William Sedgwick thought it probable that the unfruitfulness of prostitutes might in some degree be due to the same cause as that of the Australian aborigines who have had children by white men.
"It would seem as though the Israelites had had some knowledge of telegony, for in Deuteronomy we find that when a man died leaving no issue, his wife was commanded to marry her husband's brother, in order that he might 'raise up seed to his brother.' "We must omit the thorough inquiry into this subject that is offered by Mr. Blaikie. The explanations put forward have always been on one of three main lines:--(1) The imagination-theory, or, to quote Harvey: "Due to mental causes so operating either on the mind of the female and so acting on her reproductive powers, or on the mind of the male parent, and so influencing the qualities of his semen, as to modify the nutrition and development of the offspring."(2) Due to a local influence on the reproductive organs of the mother.
(3) Due to a general influence through the fetus on the mother.
Antenatal Pathology.--We have next to deal with the diseases, accidents, and operations that affect the pregnant uterus and its contents; these are rich in anomalies and facts of curious interest, and have been recognized from the earliest times. In the various works usually grouped together under the general designation of "Hippocratic" are to be found the earliest opinions upon the subject of antenatal pathology which the medical literature of Greece has handed down to modern times.
