Fig. 2. The state of the pupil when the horse is 

 brought out of the stable and placed in the shade. 



Fig. 3. The form of the pupil when the eye is 

 exposed to the direct rays of the sun. 



Fig. 4. A morbid dilatation of the pupil of the 

 eye. The black, or dark brown substance represent- 

 ed at the superior margin of the pupil is a natural 

 appearance, though sometimes mistaken for a disease. 



Fig. 5. The pupil dilated in a less degree, with 

 an incipient and general opacity of the part. 



Fig. 6. Appearance of the pupil when the eye 

 is affected with cataract. 



Fig. 7 represents a partial cataract ; that is, the 

 appearance of white or opaque spots in the pupil. 

 In this case, a considerable portion of the pupil is 

 free from those spots, particularly the centre ; so 

 that vision would not be materially impeded. 



Fig. 8 represents a similar disease, with some slight 

 variation as to the situation of the spots. 



Fig. 9. A more circular pupil, with opacity in 

 the centre and on one side. 



Fig. 10. A contracted pupil vvith considerable 

 opacity, causing almost total blindness. 



Fig. 11. A pupil of the natural size, with opacity 

 in the centre, materially obstructing vision.
