one arm "similar to" those the mother saw on the corresponding arm of her husband. Another story is that of a lady who had a great craving for raspberries before her child was born, and accordingly bore a child with a red raspberry mark on its body! In no case does Mr. Heape give any picture of the birth-mark and the thing supposed to be represented by it, nor state that he has seen either the mark or a picture of it. In no case is the statement of the mother as to her having been "influenced" as described in the narration, tested or examined in any way. These and similar stories are related to-day, and such stories have been related from time immemorial. But they are always "hear-say." The witnesses and the facts are never carefully examined, and the degree of closeness of the agreement between the mark and its supposed cause are never really demonstrated. Nor has anyone undertaken a statistical examination with the view of showing that the vague agreement of the mark with the arresting object seen by the mother is anything more than an accidental coincidence, nor (in regard to many such stories) has it been proved that the mother really did see or notice any such terrifying object as she afterwards declares (and possibly thinks) she did. Moreover, no one has carefully and scientifically made crucial experiments with animals, similar to that of the patriarch Jacob. The experiments and their record would not be difficult with animals. Though some farmers may believe that such influences do operate on their breeding dams, there is no known or recognized application of Jacob's method to the production of desired form or colour in domesticated animals. We are not concerned with "possibilities." What is needed is a series of demonstrative experiments, or critical cases. And these are, as yet, not forthcoming. Telegony is the name given to the hypothesis that the offspring of a known sire sometimes inherit characters from a previous mate of their dam. The name means reproduction (Greek, gonos) influenced by a remote agent (Greek, tele = from afar). There is no question about "possibility" here. Such an "infection" of a dam by a previous mate is not improbable. According to Darwin "farmers in South Brazil are convinced that mares which have once borne mules, when subsequently put to horses, are extremely liable to produce colts striped like a mule." On the other hand, the Baron de Parana states that he has many relatives and friends who have large establishments for the rearing of mules where they obtain from 400 to 1000 mules in a year. In all these establishments, after two or three crossings of the mare and ass, the breeders cause the mare to be put to a horse; yet the pure-bred foals so produced have never in a single case resembled either an ass or a mule.
