and thereupon made the tryal, and found thecffeft fully to an- 
ft er to my cafe, and to be moft proper for Ch;ra&eis, as there 
printed. And then I blamM not a little my own ftupidnefs, th: r. 
J did no fooner apply to my felf the hint, I might have takers 
from the Ingenious Dr. Lowers Obfervations concerning a Ble- 
Mfh in hoifes eyes , printed in Number }2. though that be no- 
thing to my cafe, forafmuch as I fee very little, if the Air be 
gloomy, or the Sky clouded -, neither have I any refort of hu- 
mors or fenfible defluxions about my eyes. 
And now give me leave to add, that if I had confulted with 
the learnedft and wifeft men living , I make no doubt but I fhould 
have been difappointed of all relief; and perhaps I might have 
loft the Cref ufcular remains of my Sight by adventurous Effayes 
upon fuch a tender Organ. Who knoweth how often the wifeft 
of Mortals are loft, whilft they trample on the remedy, that of- 
fers it felf at hand * We fee how many ingenious and laborious 
Artifts have long labour'd for the Elliptical or Hyperbolical Sec- 
don of Gaffes, hoping thereby to make that britle body oiclajs 
of more worth, than the faireft Diamonds ; yet if this were ob- 
tained toperfe&ion, I doubt it would not afford me the kindnefs 
and relief , I gain by thefe empty and dark Tubes. And now I 
hope, that all who pretend to Vertue and Philofophy, will ufe 
fuch juft fcales for the virtue of things, as to eftimate every 
thing, how cheap and contemptible foever it may feem to be, 
according as 'tis beneficial, and as it brings relief andfupply to 
the diftreffed. ' 
I muft not let this pafs, without inferring here a few Notes, 
feme of which referre to thofe Observations, you received from 
Dr. Lcrver^ and communicated in the late mentioned Num- 
1. That Horfes of an Iron gray, or Dapple-gray are frequent- 
ly inclining to loofe one or both Eyes, if back'd and hard ridden 
too foon. 
2. That in Man, and Beaft (in Horfes at leaft) the right eye is 
the weakeft, and moft frequently failing. 
3. That the pupil or black of the eye is wider and larger in 
thofe that are (hort-fighted, than inthofe that fee at greater di- ; 
itance. ■ \ ;i I y 4 J
