12 8 The Jrt of Farriery 



DMmUll's As I jufl: now faid, Dumhall ftill continued Blind, 



but a few Years afterwards, he happened to be jell- 

 ing and wrellling with one of his Neighbours, wlio 

 caught him round the Head in his Arms, and 

 fqueefed his Face againfl his Breail:, and a Button by 

 Accident happening to light againil: one of the 

 Blind Man's Eyes, it feemed to Hurt him very Sore, 

 and feme Blood was ( by the Violence of the Squeefe) 

 forced out of the Eye ; but what is moft to be 

 wondered at, the Blind-Man received Sight of that 

 Eye from this Accident ; which is more than all 

 the Surgeons, Oculifts, l^c. put together, could 

 have done by Art. And v/hofoever ihould tell me 

 he could have performed this by any Inilrument, 

 or other Contrivance, I fhould look on fuch Perfon, 

 as no more than a vain empty Coxcomb, who can 

 fay more in one Minute, than he will perform in 

 his whole Life, tho' he fhould outlive Methufclah. 



Now, in this Cafe, there is no Manner of Doubt 

 to be made, but the Cryllalline Humour of the Eye 

 mull (by the violent Squeefe of the Man's Thumb) 

 be forced out of its Capfula or that thin Covering 

 iy Anatomiils called Tunica Ara^iea ; and in fuch 

 C-i\.{t, the Rays of Light muft be brought to a Focus 

 or Point, quite in a different Part of the Eye to 

 wliat they ought to be, and of confequence the 

 Mari's Sight muft be loft while the Cryftalline con- 

 tinued in that State and Condition : And I am con- 

 vinced, this was the true Cafe ; for I could plainly 

 perceive a little of the Edge of the Cryftalline Hu- 

 mour (efpecially if I look'd fide-ways) through the 

 Pupilla or Sight of the Eye, and when this Eye 

 happened to be again prefs'd by the Button of a 

 Coat as aforefaid, the Cryftalline flipped back into 

 its proper Place, which is (as I have faid) imme- 

 diately behind the Iris, and into a fmall Cavity 

 in the Middle of the Vitreous Humour ; and by 

 this Means, the Rays became properly convergent 

 upon the Retina.
