oped brain, but the senses are much inferior to those of mammals 
in general. The sense of touch is limited, since the skin is covered 
with feathers, the quills of which end in small bulbs or hollows 
under the skin. The sense of smell is not very keen, while the 
sense of taste varies considerably in individuals. All fowls reject 
things which are objectionable to them; probably, however, this 
is as much from sight as from taste; but it is clearly demonstrated 
that they have a sense of taste quite well developed, since they 
show a partiality for certain kinds of feed, whether there is any 
great difference in the physical nature of the feeds cr not. Palata- 
bility is an important consideration in poultry feeding. The sense 
of sight is very highly developed as well as the sense of hearing.
