NASAL BONES IN CATTLE, &C. 
the face by the development of the frontals, but not so far as in 
the ox—a more complex denticulated union with the frontals 
than in the ox, because a greater extent of border is opposed, and 
they are subject to greater danger from the brutality of those 
who ought to be their protectors whether biped or quadruped— 
lying in juxta-position with a longer line of the superior border of 
the superior maxillary, but having a more cartilaginous union with, 
or not coming into contact at all with the anterior maxillary • there¬ 
fore, in a manner, unconnected with two bones, the lachrymal 
and the anterior maxillary, to which the nasals are united by 
suture in the horse and the ox. The nasal bones are not prolonged 
further below the posterior process of the anterior maxillary than 
in the ox, because here, too, that bone does not contain any teeth, 
and is of comparatively little bulk ; and the bones terminate in 
two sharp points, as in the horse, and, uniting together, form, as 
in him, one central and sharp projection. This and the borders of 
the anterior maxillary give attachment to muscles sufficiently 
powerful to enable the upper lip of the sheep to compress and 
assist in breaking off the herbage ; or that which would be want¬ 
ing in power is supplied by a peculiar quickness andjerkiness of 
motion in the manner in which this animal grazes. The broad 
muzzle of the ox would be a deformity in the sheep; and the 
sheep in a state of nature is possessed of considerable activity and 
speed, and requires thinner and more flexible nostrils, to expand 
and accommodate themselves to the increased and more laborious 
respiration. The nasal bones in the sheep are more arched and 
rounded than in the horse, with, in many of the breeds, the pro¬ 
minency on the superior part, and w hich, in the horse, has been de¬ 
signated by the name of a Roman nose. There is also the same 
concavity of the nasal bones on their internal surface, forming the 
same enlarged superior meatus as in the ox, and for the same 
purpose. 
In the swine the nasal bones are forced farther down into the 
face than in the horse, ox, or sheep; but they are comparatively 
larger than in either of them, and present also points of differ¬ 
ence suited to the situation and destiny of the animal. They are 
attached to the frontals in a slightly curved direction across the 
face, and the suture is fully as complicated as, and considerably 
stronger than the same suture in the horse. It is botli squamous 
and denticulated. They are, as in the sheep, cut off from imme¬ 
diate contact with the lachrymal bones, by the interposition of a 
projection of the frontals on each side. The suture betw een them 
and the superior maxillary is mortised ; the anterior maxillary 
sends up a deep and broad process more than half the length of 
the nasals, and the suture between is peculiarly strong; the bony
