pression, which denote the energy, the nobleness, and the distinction 

 of the horse. 



Such are the numerous beauties sought for in this region. 



Defects. The defects of the eye are not less important to 

 consider. We mention : 



1. The small eye, or pig's eye, in which the ocular globe is little 

 developed, the palpebral opening narrow, and the eyelids thick. It 

 accompanies, in general, a lymphatic temperament and a eonimon an- 

 cestry. It is said to be an index of a predisposition to diseases of this 

 region. 



2. The concealed eye, ordinarily small and but little salient, but 

 surmounted by a prominent and voluminous eyelid which partly con- 

 ceals it, implies a sullen and treacherous disposition and a natural 

 aggressiveness. 



3. The bovine eye, or gross eye, characterized by an excessive con- 

 vexity of the cornea, is very salient between the eyelids, little mobile, 

 ungraceful, and without expression. It is often predisposed to myopia. 



4. The hollow eye is seen only in old horses and in those deterio- 

 rated by age and hard labor. It is retracted into its orbit, covered 

 by flabby eyelids, surmounted by a hollow supra-orbit, and often 

 weeping. 



5. The circled or bordered eye is one in which a portion of the scle- 

 rotic around the edge of the cornea is visible through the palpebral 

 opening. It is very unseemly. 



6. The eyes are sometimes unequal in size; either from excess or 

 deficiency of growth. When this disproportion is not congenital, it is 

 a subject of apprehension, from always being a constant result of 

 repeated attacks of periodic fluxion. The eye which has experienced 

 repeated attacks of this disease is always the smaller. Its function is 

 practically lost. 



7. The myopic eye is very convex ; it resembles much the bovine 

 eye, save the volume, which is not exaggerated. It is observed most 

 frequently in young animals, and renders them irresolute and liable 

 to shy. 



8. The hypermetropic eye is, on the contrary, not sufficiently con- 

 vex. Such animals as possess it discern very poorly objects which are 

 near, whilst those which are at a distance can be easily recognized. It 

 predisposes them to stumbling and uncertainty of the limbs. 



9. A wall-eye is one in which the iris is of a pearly-white color, 

 being deprived of its pigment. Apart from the visual effect, it is none 

 the less excellent functionally.
