Clark reports the birth of a child whose father had a stiff knee-joint, and the child's knee was stiff and bent in exactly the same position as that of its father.
Telegony.--The influence of the paternal seed on the physical and mental constitution of the child is well known. To designate this condition, Telegony is the word that was coined by Weismann in his "Das Keimplasma," and he defines it as "Infection of the Germ," and, at another time, as "Those doubtful instances in which the offspring is said to resemble, not the father, but an early mate of the mother,"--or, in other words, the alleged influence of a previous sire on the progeny produced by a subsequent one from the same mother. In a systematic discussion of telegony before the Royal Medical Society, Edinburgh, on March 1, 1895, Brunton Blaikie, as a means of making the definition of telegony plainer by practical example, prefaced his remarks by citing the classic example which first drew the attention of the modern scientific world to this phenomenon. The facts of this case were communicated in a letter from the Earl of Morton to the President of the Royal Society in 1821, and were as follows: In the year 1816 Lord Morton put a male quagga to a young chestnut mare of 7/8 Arabian blood, which had never before been bred from.
The result was a female hybrid which resembled both parents. He now sold the mare to Sir Gore Ousley, who two years after she bore the hybrid put her to a black Arabian horse. During the two following years she had two foals which Lord Morton thus describes: "They have the character of the Arabian breed as decidedly as can be expected when 15/16 of the blood are Arabian, and they are fine specimens of the breed; but both in their color and in the hair of their manes they have a striking resemblance to the quagga. Their color is bay, marked more or less like the quagga in a darker tint. Both are distinguished by the dark line along the ridge of the back, the dark stripes across the forehand, and the dark bars across the back part of the legs."The President of the Royal Society saw the foals and verified Lord Morton's statement.
"Herbert Spencer, in the Contemporary Review for May, 1893, gives several cases communicated to him by his friend Mr. Fookes, whom Spencer says is often appointed judge of animals at agricultural shows. After giving various examples he goes on to say: 'A friend of mine near this had a valuable Dachshund bitch, which most unfortunately had a litter by a stray sheep-dog. The next year the owner sent her on a visit to a pure Dachshund dog, but the produce took quite as much of the first father as the second, and the next year he sent her to another Dachshund, with the same result. Another case: A friend of mine in Devizes had a litter of puppies unsought for, by a setter from a favorite pointer bitch, and after this she never bred any true pointers, no matter what the paternity was.'
"Lord Polwarth, whose very fine breed of Border Leicesters is famed throughout Britain, and whose knowledge on the subject of breeding is great, says that 'In sheep we always consider that if a ewe breeds to a Shrop ram, she is never safe to breed pure Leicesters from, as dun or colored legs are apt to come even when the sire is a pure Leicester. This has been proved in various instances, but is not invariable.' "Hon. Henry Scott says: "Dog-breeders know this theory well; and if a pure-bred bitch happens to breed to a dog of another breed, she is of little use for breeding pure-bred puppies afterward.
Animals which produce large litters and go a short time pregnant show this throwing back to previous sires far more distinctly than others--I fancy dogs and pigs most of all, and probably horses least. The influence of previous sires may be carried into the second generation or further, as I have a cat now which appears to be half Persian (long hair). His dam has very long hair and every appearance of being a half Persian, whereas neither have really any Persian blood, as far as I know, but the grand-dam (a very smooth-haired cat) had several litters by a half-Persian tom-cat, and all her produce since have showed the influence retained. The Persian tom-cat died many years ago, and was the only one in the district, so, although I cannot be absolutely positive, still I think this case is really as stated."Breeders of Bedlington terriers wish to breed dogs with as powerful jaws as possible. In order to accomplish this they put the Bedlington terrier bitch first to a bull-terrier dog, and get a mongrel litter which they destroy. They now put the bitch to a Bedlington terrier dog and get a litter of puppies which are practically pure, but have much stronger jaws than they would otherwise have had, and also show much of the gameness of the bull-terrier, thus proving that physiologic as well as anatomic characters may be transmitted in this way.
After citing the foregoing examples, Blaikie directs his attention to man, and makes the following interesting remarks:--"We might expect from the foregoing account of telegony amongst animals that whenever a black woman had a child to a white man, and then married a black man, her subsequent children would not be entirely black. Dr. Robert Balfour of Surinam in 1851 wrote to Harvey that he was continually noticing amongst the colored population of Surinam 'that if a negress had a child or children by a white, and afterward fruitful intercourse with a negro, the latter offspring had generally a lighter color than the parents.'
