these adventitious mixtures ; but we do not believe that any of the established and recognized 
"breeds of dogs are the result of such a process. There is, no doubt, a tendency to branching 
•out into varieties, implanted by nature as well in dogs as other animals, and these varieties, 
Iranning in the grooves Providence has furnished for them, become fixed and permanent. " It 
must be observed," says Prichard, speaking of the climatic differences in the hair of dogs, " that 
these as well as other traits in the breed of dogs have in the first place a relation to climate, but 
have yet the character of permanent varieties, which remain for generations constant and unde- 
viating. The varieties of the dog tribe' have become inrmanent varieties P 
But now ai'ises another question : admitting that the dog is an original and distinct race, are 
all dogs of the same species ? Are the silken lap-dog and the Cuban blood-hound of the same 
parentage ? Are the fox-hound that follows by scent, and the greyhound that follows by sight ; 
the sly lurcher and the frank Newfoundland dog ; the submissive spaniel and the gruff mastiff ■; 
the terrier that hunts rats, and the bull-dog that pinions a bull ; the Dalmatian that struts behind 
a coach, and the cur that turns up his nose at all the world as he trudges behind a tinker ; — are 
these all of one species ? Can we, by any process, conceive the grand and generous ally of the 
monks of St. Bernard to be of the same race as the impudent and spiteful pug that lives only to 
snap at every stranger's heels ? Can we conceive the sleek, long-legged, graceful Italian grey- 
hound and the vulgar, woolly poodle to be brothers? 
These questions have been often put and variously answered. The general conclusion is, alike 
by those who find the parentage of the dog in the wolf and those who assert its originality, that 
all the kinds of dogs are of one descent and one species. The diversities which we see in form, 
size, color, instincts, and aptitudes, and even the differences of structure already alluded to, are 
all held to be but the results of that principle of variation and development which nature has 
pronded for in many other instances, through the influence of climate and condition.
