modified that, as feveral writers have obferved, it 

 does not now clofely referable any exifting native 

 dog in Newfoundland." 1 



With regard to this variety of canine breeds, 

 their extinction and the rife of others in their 

 place, Mr. Darwin again fays : " Through the 

 procefs of fubftitution the old Englifh hound has 

 been loft ; and fo it has been with the Irifh wolf- 

 dog, the old Englifh bulldog, and feveral other 

 breeds, fuch as the alaunt, as I am informed by 

 Mr. Jefle. But the extinction of former breeds is 

 apparently aided by another caufe ; for whenever 

 a breed is kept in fcanty numbers, as at prefent 

 with the bloodhound, it is reared with fome 

 difficulty, apparently from the evil effects of long- 

 continued clofe interbreeding." 2 Many an ex- 

 tinct breed (unlefs the animals exifted only in the 

 imagination of their painters) may be feen in 

 Berjeau's illuftrations of dogs, taken from old 

 fculptures and pictures. And every admirer of 

 Diirer's pictures muft remember the curious hairy 

 dog with large ears, fomething like an eccentric 

 Scotch terrier, which appears in fo much of his 

 work; while at other times a dog is introduced 

 which refembles a modern bull-terrier pup, both 

 of which, however, it would be difficult to find 

 examples of at the prefent day. 



Mr. J. E. Harting confiders that all the dif- 

 ferent breeds of our dogs may be conveniently 

 deduced from the croffing of fix large groups :
