FUNGOID GROWTHS.

to ascertain the exact position occupied by the defect: upon all this 
evidence put together, make up your opinion. 
To distinguish between the different kinds of cataract, apply the bella- 
donna. Next place the horse near a window or 
under a door. Should the sun shine, have the 
animal led into the full glare of day. Look 
steadily into the eye from different points of 
view. Then have the horse’s head moved about, 
all the time keeping your sight fixed upon the 
part you are desirous of inspecting. 
Should one spot continue in every position, 
of one bulk, and of one aspect, never becoming 
very narrow and always occupying one place 
throughout the examination,—it is a lenticular 
cataract that is beheld. 
If the whiteness changes appearances, in some 
positions seeming very thin or perceptibly less 
bulky, it is assuredly a capsular cataract which 
is inspected. 
Most cataracts may either be partial or com- 
plete; but a spurious cataract is always partial, 
never permanent, and invariably caused by vio-

lence. 
For spurious cataract, treat the injury to the exterior of the eye. 
For other cataracts, do nothing: there is no known medicine of any 
beneficial effect. However, it is well to add, the author’s and the gen- 
eral opinion favors the absorption of cataract; or that these opacities 
may appear and after a time go away without the aid of medicine. 
Nevertheless, to hasten such a process, have the interior of the stable 
colored. However much in favor a clean white wall may be with grooms 
or with the lower order, exercise an informed judgment; have the wall 
shaded of the tint most pleasant to the inhabitants’ sight, and the 
prospect of recovery will by so trivial an outlay be materially facilitated. 
FUNGOID TUMORS WITHIN THE SUBSTANCE OF THE EYE. 
These, fortunately, are rare affections. We know of no immediate 
cause for their production. No man can prophesy their appearance. 
The horse, to human judgment, may enjoy the top of health; may be in 
flesh and full of spirit—altogether blooming. Nevertheless, the action 
of the legs may perceptibly grow higher, and the ears become more 
active. The animal will wait to be urged or guided, when the road is
