called cases brought under his notice) it does not bear 

 " critical inspection for a moment." 



Every year an immense number of telegony experiments 

 (mostly unintentional) are made with dogs, and though, 

 as a rule, no records of any value are kept, it would be 

 possible to submit a large amount of evidence to show 

 that, even when the circumstances are most favourable, 

 "infection" has been conspicuous by its absence. I shall, 

 however, only give the results of three experiments. 



1. Hepsy, a black-brindled Scottish terrier by Kilgreggan 

 out of Bannockburn Lady (two famous pure -bred terriers 

 by " Champion " Dundee), had first of all a litter of pups 

 to a curly-haired liver- and- white cocker-spaniel. These 

 pups being of a brown-and-white colour, and decidedly 

 spaniel -like in build, proved that Hepsy, though inbred, 

 was capable of being influenced by a sire of a different 

 strain. In due time Hepsy was mated with Roden, a pure- 

 bred dog of her own breed. Gorst, the result of this 

 union, was a typical black-brindled terrier with the small 

 erect ears and wiry straight hair characteristic of the breed 

 — i.e., there was nothing about Gorst suggestive of the soft 

 wavy hair and large drooping ears of Hepsy's previous 

 mate, the cocker-spaniel. 



Hepsy, next mated with " Champion " Revival, produced 

 Rustic Beauty, who was as true to the terrier type as her 

 half-brother Gorst. 



Rustic Beauty proved as free of infection as her mother. 

 To Heather Prince she produced " Champion " Gair, and 

 to another dog she gave birth to a daughter, which, mated 

 with her half-brother Gair, yielded " Champion " Glory. 



That the subsequent offspring of Hepsy were true to 

 type is attested by the fact that Gorst, Gair, and Glory 

 were all noted prize-winners.^ 



2. A pure-breed Scottish deerhound, while in the posses- 

 sion of Professor A. E. Mettam, B.Sc. (now Principal of 

 the Royal Veterinary College, Dublin), had first a litter 

 of pups to a retriever. All these pups took more after the 

 retriever sire than their deerhound dam. Subsequently

 these terriers from Mr Marshall, their breeder.
