"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. That there were medical writers before the time of
Hippocrates cannot be doubted, and that the works ascribed to the
"Father of Medicine" were immediately followed by those of other
physicians, is likewise not to be questioned; but whilst nearly all the
writings prior to and after Hippocrates have been long lost to the
world, most of those that were written by the Coan physician and his
fo
