may be turned a little fideways, and his Sight lofl, 

 although the Eye keeps its due Fullnefs and Propor- 

 tion : But this Diforder cannot well be known, but 

 by thofe who underftand the Anatomy of this lb 

 admirably contrived Organ of the Body. 



I remember a very odd Cafe, fomething like 

 this I am treating of, which happened to a Man*s 

 Eyes, and, as it is I think fcarcely to be parallel'd, 

 I muft beg leave to name it in this Place. 



The Cafe was this ; one Hefiry Dumhall, near A very odd 

 V/igan^ happened to receive a Stroke upon one of C*'^^- 

 his Eyes in a Quarrel, which entirely deprived him 

 of Sight on that Side, although his Eye was as 

 plump and full as the other ; nor did he tell me 

 when I favv it, that he had much Pain after the 

 Misfortune 



I obferved the Humours of the Eye difplaced, 

 though I had reafon to believe their Coats or Cover- 

 ings pretty whole and entire. The Cryftalline was 

 advanced nearer the Pupil (or little Hole in the 

 middle of the Iris) than it ought to be, and with 

 all turned fide-ways ; fo that by this ( I mean the 

 Cryftalline's being advanced nearer the Pupil ) the 

 Rays of Light mull fall confufedly upon the Retina, 

 in tiie fame Manner as when, in the Camera Ob/cur a 

 before defcribed, the Paper which reprefents the 

 Reti7ia is held at too great a Diilance from the 

 Convex Glafs which reprefents the Cryllalline 

 Humour. So that finding the Eye in this Pickle, 

 I advifed the poor Man to reft contented, and not 

 throw away his Money upon ignorant Itinera-nts^ 

 which we daily fee is too often the Cafe of the de- 

 luded Vulgar : But this Man's Evils did not end 

 I here ; for a few Years afterwards he happened to 

 I fall out with one of his Neighbours, who in the 

 I Fray twifted his Finger into poor Dumball's Hair, 

 I and fqueezed his Thumb with fuch Violence into 

 his Eye, that, as the firft, fo was the other Eye 

 loft, and as near as poflible remained in the like Si- 

 i tu:ition and Circumftances with it. And this in-
