VETERINARY OPHTHALMOLOGY.

Right Eye .—Superficial examination shows already that 
le pupil is contracted considerably—elliptic ; the eye is sensi- 
le to the light and eyelids are partly closed when exposed 
> bright natural light. When a lighted candle is passed be- 
>re the eye two lights are reflected, indicating that the cor- 
ea and anterior surface of crystalline lens are transparent, 
xamined obliquely with or without No. 2 lens the iris is seen 
dherent (synechiae) to the crystalline lens, dark-colored de- 
osits are seen at two or three places, they are fixed, immov- 
ble; they belong to the crystalline lens. Other deposits of 
ime color are seen fixed, immovable at one end and the 
ther end moving to and fro, as the limb of a tree shaken by 
le wind. These belong to the vitreous body. Examined 
dth the ophthalmoscope, the above alterations are much more 
isible, but these deposits prevent the rays of light to pene- 
rate sufficiently the transparent parts of the eye to see the 
ottom of the organ. We only see the dark red shadow, but 
tie details escape investigation. 
Diagnosis and Prognosis .—Formation of a cataract, disease 
f vitreous body, and probably choroiditis with gradual atro- 
hy of retinia; actual partial blindness, with great tendency 
f aggravation and complete blindness as final result. 
Left Eye .—Superficial inspection shows pupil dilated tc 
:s extreme limit, immovable, the light of an ordinary No. 10 
lectric lamp directed suddenly into the eye causes no effect 
n pupil. A lighted candle passed before the eye shows two 
effected lights so that the cornea and anterior surface of 
rystalline lens are transparent. Examined obliquely, with 
•r without No. 2 lens, the same alterations of the crystal- 
ine lens and the vitreous body are observed as in the other 
ye, but larger and more numerous. The ophthalmoscopic 
xamination has no better result than with other eye, only a 
hade of the choroid being perceived. The cornea seems insen- 
ible, and to test it, a piece of paper is carefully applied, 
voiding the lashes, and made to touch the cornea; no sign of 
ensibility is evinced. In order to further test it, 6 drops of 
olution of eserine (1-25) are placed in the eye three times a 
lay during five days. If the eye is not paralyzed, the pupil
