fox, erect ears, and their instincts lead them to watch and follow the flocks. The mastiff, the greyhound, the large Dane, and the Irish hound, have, besides the resemblance of form and long snout, the same dispositions; they love to course and to follow horses; they have but indifferent noses, and hunt rather from their sight than their scent. The real hunting dogs are the hounds, harriers, terriers, spaniels, and water-dogs, and notwithstanding they differ in figure yet they have all thick muzzles, the same instincts, and therefore ought to be classed together; the only difference between the water-dog and the spaniel is, that those with long bushy hair take to the water with more facility than those whose hair is short and straight. The small Dane and Turkish dog must be ranked together, since they are in fact the same; the latter having only lost his hair by the effects of heat. Lastly, the bull dog, (_fig. 47._) seems to form a particular variety, and even to belong to a particular climate; he is a native of England, and it is difficult to preserve the breed even in France. The pug-dog, (_fig. 48._) and mastiff, (_fig. 49._) are mongrels from him and they succeed much better; they all have short muzzles and but little scent. The acuteness of the scent, however, seems in general to depend more on the largeness than the length of the muzzle, for the greyhound, large Dane, and the Irish greyhound, have their scent very inferior to the hound, hairier, terrier, spaniel, and water-dog, although their muzzles are more than proportionally longer. _Engraved for Barr's Buffon_ [Illustration: FIG. 46. _K.

I shall not here take upon myself to enumerate all the qualities of the sporting dogs; it is well known how much the excellence of their sense of smelling, together with their education, gives them the superiority over other animals; but these details belong only to a distant part of Natural History. Besides the tricks and dexterity, though proceeding from nature alone, made use of by wild animals to elude the researches, or to avoid the pursuit of the dogs, are perhaps more wonderful than the most refined methods practised in the art of hunting.
