DOG. 275 
Dog (adds this author) cannot breed together, 
and produce an intermediate race : their disposi- 
tions are opposite, and their constitutions differ- 
ent: the Wolf also lives longer than the Dog; the 
former breeds but once a year, but the dog twice 
or thrice. These distinctions are more than suf- 
ficient to demonstrate the two animals to be of 
very different kinds. Besides, on a closer inspec- 
tion, we easily perceive that even externally the 
Wolf differs from the dog by essential and uni- 
form characters. The appearance of the head and 
the form of the bones are by no means the same. 
The cavity of the eye in the Wolf is placed ob- 
liquely; the orbits are inchned; the eyes sparkle 
and shine in the dark: instead of barking the 
Wolf howls; his movements, though quick and 
precipitate, are more uniform and equal : his body 
is stronger, but not so flexible : his limbs are finner^ 
his jaws and teeth larger^ and his hair coarser 
and thicker." All this, however^ was said long 
before the celebrated experiments had been made, 
which have clearly proved that a hybrid offspring 
may be obtained from the Dog and the Wolf^ and 
that the breed may be continued between the hy- 
brids themselves^ or with other Dogs. In his 
supplemental volumes the Count de Buffon him- 
self has amply detailed some experiments of this 
kind, and has given engravings of the descend- 
ants. But though the Wolf and the Dog may 
thus breed together, and their progeny may also 
prove fertile, yet this can hardly be allowed a 
sufficient proof of a real identity of species. The
