 the European and west-oriental races of Dogs, the 

 connection being mainly through the Jackal and 

 the Indian Wolf (Canis pallipes). The races partly 

 lead back into prehistoric times. Closest to the 

 Jackals we have the so-called Turf-dog, known 

 from the turf deposits of the lake dwellings, and 

 which is probably the ancestor of our Pomeranian 

 dogs. Allied to it we have the terriers and turn- 

 spits. From Canis pallipes is descended the so- 

 called Bronze-Dog, which most probably came to 

 Europe with human immigrants from Asia, and 

 with it the sheep-dog of Central Europe, the larger 

 sporting dog, the poodle, cur-dog, and bull-dog. 

 The ancestor of a third group may perhaps be 

 found in the large jackal (Canis lupaster) of North 

 Africa, to which we should also have to refer the 

 ancient Egyptian dog, the Oriental street dog, and 

 the wild dog of Africa. 



This does not as yet settle the question as to 

 which fossil forms may be concealed among the 

 numerous races of the domestic dog. Various con- 

 jectures have been made, none of which, however, 

 are based upon any special reasons. According to 

 Blainville's opinion, a Diluvial species of a gentle 

 and sociable nature no longer existing in a wild
