INTRODUCTION. 101 
Europe, the fiercest dogs, such as the packs kept by 
the feudal nobility for boar and wolf hunting, were 
invariably fed on bread.* If the dog proceeded 
solely from one typical species, allowance being 
made for some modifications as above specified, all 
his developments would continue within the circle 
of powers and faculties belonging to the original 
type. They might diminish, but increase only in a 
trifling degree. We may infer, that food or climate 
would not truncate and widen the muzzle, nor raise 
the frontals, nor greatly alter the posterior branches 
of the lower jaw-bone, as in mastiffs.t It would 
scarcely have the effect, in other cases, of producing 
a high and slender structure, while it took away the 
sense of smelling and several of the best moral qua- 
lifications resulting from domesticity and education, 
as occurs in greyhounds. All these qualities appear 
to us indications of different types, whose combinable 
properties have enabled man to multiply the species 
of dogs into the several races his wants required. 
In these views we expect to have the concurrence 
of all sportsmen, who have studied the characters 
of the animals more than the books of systematic

and the household institutions of the dukes of Burgundy ; 
the ancient Welsh laws, &c. 
+ “ The deep jaw-bones of (some) domestic dogs are inde- 
pendent of the more general character of the family, and 
indicate a corresponding possession of actual physical power, 
as in the lion and jaguar, compared with the more insidious 
habits of the puma, we find a similar correspondence.—Ans-
