ANATOMY OF REGIONS. 
155 
species of animals, according to the different breeds. They are often 
missing, and more so in females than in males. 
The fronto-parietal region of the pig, is considerably elongated from 
upwards, downwards—the fissures exist in the thickness of the two bones. 
In carnivorous , the region corresponding to the frontal bone, oc¬ 
cupies about the middle of the anterior face of the head. In short 
head breed it corresponds only to the frontal; the temporal regions, 
enormously developed, unite above the frontal, and bound it above and 
on the sides ; the frontal portion of the head stops a little above the 
inferior border of the orbits. 
SECTION 2.—NASAL REGION. 
This is limited superiorly by the frontal region, on the sides by the 
orbito-palpebral and alveolo-labial, downwards by the point of the nose. 
It has for base the nasal bones, the anterior portion of the superior max¬ 
illary bones; all the part extending from the frontal region to the nos¬ 
trils is called superior nasal , or of the chanfrin j the nostrils will be 
described separately. 
a .—SUPERIOR NASAL REGION, OR OF THE CHANFRIN. 
Much wider superiorly than inferiorly, it is flat in its middle, which 
represents a kind of elongated V. with the opening turned upwards, the 
sides run smoothly obliquely outwards, so as to unite with the lateral 
faces of the head. 
The form of that region varies much, according to breed, and even 
individuals; it is in intimate co-relation with that of the forehead. It 
ought td be straight and wide. Very often a depression, which gives to 
the head a peculiar aspect (rhinoceros head), is found on a point where 
the nose piece of the halter passes; this form may diminish the vertical 
diameter of the nasal cavities, but becomes of some importance only 
when excessively developed. The skin of the nasal region is more 
movable and loose inferiorly than superiorly. Through it, in the whole 
extent of the region, one can readily feel and well define all the different 
parts situated underneath, and thus all deformations, callus, osteitis, &c.., 
can be easily detected. Exactly in the middle of the region, the suture 
of the two nasal bones, always incomplete inferiorly, is easily detected. 
On each side of the branches of the V, representing the median 
part, one will observe a wide depression, slendering backwards, and 
continued along the ascending apophysis of the small maxillary bone; 
on the outside border of the groove, a longitudinal movable promin-
