162 THE DOMESTIC DOG. 



than one hundred and eighty-five varieties, nor do we think his 

 enumeration excessive. He groups these varieties in seven categories, 

 as follows : (1) House Dogs, 48 varieties; (2) Spaniels, 30 varieties ; 

 (3) Terriers, 12 varieties; (4) Hounds, 35 varieties; (5) Mastiffs, 

 19 varieties; (6) Greyhounds, 35 varieties, and (7) Hairless Dogs, 

 6 varieties. 



With the ancient Romans, dogs seem to have been classed as either 

 Canes mllatici (House Dogs), Canes pastorales (Shepherd Dogs), or 

 Canes venatici (Sporting Dogs) ; the last category being subdivided into 

 A, pugnaces (probably like our Bull-dogs and Terriers), B, nare 

 sagaces (hunting by scent), and C, pedibus celeres (like our Grey- 

 hounds). 



Lieut.-Col. C. Hamilton Smith * grouped the breeds thus : 

 (1) Wolf-Dogs (such e. g. as the Esquimaux, Newfoundland, St. 

 Bernard, and Pomeranian Dogs, with the Shepherd's Dog and great 

 AVolf-dog) ; (2) Watch-dogs (such as the German Boar-hound, the 

 Danish Dog, &c.) ; (3) Greyhounds (including the Lurchers and the 

 j*V Egyptian street-dog) ; (4) Hounds (including the Bloodhound, Dalma- 

 tian Coach-dog, Turnspit, Spaniel, and Maltese Dog) ; (5) Cur-dogs 

 (including with the Terrier the Pariah dog of India and the dogs of the 

 natives of Tierra del Fuego), and (6) Mastiffs (including that of Thibet 

 with the Bull-dog, the Pug-dog, and the little Danish Dog). 



Mr. Edmund Harting, E.L.S., a naturalist who has paid so much 

 attention to the birds and beasts of our Islands, has proposed f to 

 arrange the breeds in six groups (founded to a certain extent on the 

 form and development of the ears), which he regards as perhaps affording 

 an approximation to a natural classification. These groups are : 

 I. Wolf-like dogs ; II. Greyhounds ; III. Spaniels ; IV. Hounds ; 

 ,V. Mastiffs; VI. Terriers. 



By a judicious crossing of these half-dozen types, he believes it 

 possible to produce every one of the present existing races of domestic 

 dog.
