12 ORIGIN OF THE DOG. 



again, showing plainly that their original normal type, differed 

 from that of the wolf. 



Another most conclusive proof of the non-lupine origin of 

 all the varieties of the dog, is the few fossil remains which 

 have been found in the ossiferous caverns. 



The canis Spelaeus of Goldfuss, the fossil remains of which 

 were discovered at Gailenrenth, differed materially in the 

 skull from the wolf, the muzzle being decidedly broader and 

 blunter. 



Kauf describes the Agnotherium, as an animal allied to 

 the dog but to have equalled a lion in size. 



Professor Low in his domesticated animals of Great Britain, 

 under the molossian group says : " We do not know of any 

 species of canis yet existing in a natural state, which may be 

 regarded as the parent stock of the mastiff, though such may 

 exist or have existed, is rendered probable by the characters 

 of the race, which have remained constant from age to age, 

 and distinguished the true mastiff from every other race of 

 dogs."
