Io INTRODUCTORY CHAPTER. 
As before remarked, this division is on the whole founded on 
natural laws, but there are some anomalies which we shall en- 
deavour to remove. For instance, the greyhound is quite as ready 
to hunt in packs as any other hound, and is only prevented from 
doing so by the hand of his master. The same restraint keeps 
him from using his nose, or he could soon be nearly as good with 
that organ as with the eye. So also Cuvier defines his sixth 
section as “having an inclination to chase and point birds,” 
whereas they have as great, and often a greater, desire for hares 
and rabits. Bearing, therefore, in mind these trifling defects, we 
shall consider the dog under the following heads :— 
Cuap. I, Wild and half-reclaimed dogs, hunting in packs. 
Cuap. II. Domesticated dogs, hunting chiefly by the eye, and 
killing their game for the use of man. 
Cuap. III. Domesticated dogs, hunting chiefly by the nose, and 
both finding and killing their game. 
Cuar. IV. Domesticated dogs, finding game by scent, but not 
killing it; being chiefly used in aid of the gun. 
Cuar. V. Pastoral dogs, and those used for the purposes of 
draught. 
Cuar. VI. Watch dogs, house dogs, and toy dogs. 
Car. VII. Crossed breeds, retrievers, &c.
