Owners were very apt to tumble in the day-time, if it were bright 
and Sun-lhine, but traveTd very well and fecurely in the even- 
ing and in dark cloudy Weather. 
What the caufe may be of that fungous ExcrefTence, or why 
Horfes are peculiarly obnoxious to it , or what kind of Horfes 
moftj I have not confidered. But, I cannot think, it comes 
from draining in great draughts , and races, orfrom hard travel, 
becaufe I have feen very large Spunges f as I may call them ) in 
young Horfes eyes of 2 and 4 years old, before they were back- 
ed> which, after they have been taken up from grafie, and kept 
with dry meat, have very much abated, and afterwards being 
turn’d to grafie in the Spring tocleanfe and cool their bodies^ 
have increafed again to the wonted bignefs. But whether it were 
from their moift feeding, or holding down their heads to eat 
( whereby there might be a greater defluxe of humors to that 
part ) I cannot determine. But for as. much as there are few 
Horfes quite free from this evil , and many rendred very inconsi- 
derable by it, I will recount the moft remarkable Cafes, which 
make Horfes moftufelefs andfufpe&ed 5 
1. The more and greater thofe Excrefcences are , the more 
the pupill of the Eye or the Sight is in danger of being quite 
obftru<aed| which you may farther examine by turning the 
Horfes Eye to the light, and obferving, how much of the 
pupill they doe obftrudt 
2. Hhdespunges on the upper edgeof theMvea are apt to 
grow the large/!, and hinder the Sight moft, 
J.That which grows on the middle of the 2 /^, does more hin- 
der the fight by diflra&ing the Objeft, than that, which grows in 
either Corner or angle of it. 
As for the Cure , I-foppofe there can be none exfpe&ed, but 
from a dry ing kind of dyet-; though perhaps outwardly fome- 
thingmaybe devifed to firadow the Eyes, and keep them from 
being nakedly expofed to the Sun, whereby the pupili\m\\ not be 
fo clofely contra&ed, and confeqaently the Sight not fo much
