TELEGONY AND EEVEKSION. 135 



Lord Morton and his followers believed the Arab mai-e 

 had been "infected," because her subsequent progeny to a 

 black Arab horse had stripes and a more or less upright 

 mane. If, however, purely-bred horses have sometimes a 

 hog-mane and as many stripes as the Gore Ouseley " colts," 

 how is it possible to prove that "infection" has occurred 

 in any given instance ? To take a concrete case, to what 

 extent would Mulatto's second foal require to differ from 

 an ordinary foal in order to prove " infection " has taken 

 place ? and, more especially, will the telegonous foal 

 require to resemble Matopo (the previous sire) or one of 

 Mulatto's or Matopo's less remote ancestors ? 



Hitherto experimenters seem to have invariably looked 

 for some resemblance to the previous sire in the pure-bred 

 subsequent offspring, and to have neglected or considered 

 worthless resemblances to remote ancestors. The late Sir 

 Everett Millais (who, as already mentioned, made all sorts 

 of experiments during a breeding experience of nearly 

 thirty years' standing, and made over fifty special experi- 

 ments to induce a case of, telegony for Mr. Romanes) 

 records what he considered a perfectly authentic instance 

 of telegony.* In this case a pure-bred fox terrier " was 

 spotted exactly like a Dalmatian." The litter previous to 

 the one in which the spotted fox terrier appeared was 

 sired by a Dalmatian, and hence it was inferred that " in- 

 fection " had taken place, the result being in this case a 

 striking resemblance on the part of the subsequent off- 

 spring to the previous sire. 



At a meeting of the Zoological Society held on No- 

 vember 17th, 1896, "Mr. Chalmers Mitchell exhibited 

 and made remarks on a supposed case of telegony as 

 shown by a fox terrier whose mother, a pure fox terrier, 

 had previously bred some mongrel dachshunds." Sir 

 Everett Millais " denied that the specimen exhibited any 

 trace of the influence of the dachshund sire of the previous 

 litter, and traced the divergences of the puppy from the 

 modern fox terrier type to the original source of the
