Anat. Char. : " The muzzle more or loss shortened ; the skull 

 high ; the frontal sinuses considerable ; the condyle of the lower

 have the additamentary toe, or dew-claw so called. From the colly, of 

 little more than twelve inches in height, to the Apennine of nearly three feet, 

 one common character prevails among them, of fidelity, indefatigable industry, 

 and intelligence, with a deportment singularly grave throughout the race. 

 The origin of this dog is difficult to trace, particularly from the sources pointed 

 out by the naturalists of the last century ; yet if we direct our attention closely 

 to the siibject, we shall detect a very near resemblance between him and some 

 of those specimens derived from Australia and high northern latitudes, but 

 which, it may be observed, differ among themselves ; the dog used to prevent 

 the destructive attack of wolves on the rein-deer, and which drives them to the 

 fold, being, we are told, not the same with tliat used about the Mackenzie 

 river.
