this Operation with Succefs, that he fails in the At- 

 tempt : But then I will not take his Judgment, but 

 my own, whether the Dillemper be a Gutta Serena 

 or no : For I know very well this common Trick Some Ac- 



of Dr. T r^njiz. that he frequently calls a"^'-"'^^^ 



Catara^ or Glaucoma by the Name of a Gutta pc - " iV to 

 Serena^ when there are no better Judges than him- the ^— -«. 

 felf by ; and therefore he is faid ( by the ignorant 

 By-ftanders) to cure a Gutta Serena^ when he has 

 only done what many a one before him has, (with- 

 out a Quarter of the Noife he makes, ) njix. couched 

 a CataraSf. But this the Do6lor thinks is too bald 

 an Expreffion ; and notvvithftanding it is true, yet 

 it fecms Truth will not always take with the World 

 if in a plain Drefs. Therefore this Itinerant cun- 

 ningly ftyles fuch Operation (different from our 

 Forefathers ) by his common Term of Remo-ving the 

 Diforders of Sights or Depreffing a Glaucoma ; for 

 the Word Catara^ would be too intelligible to the 

 Country People, and would hinder the Dodlor's 

 Bufmefs. 



I cannot part with this Fellow, who travels up 

 and down the Kingdom, and pretends that he can 

 perform fuch Wonders in removing the Diforders of 

 Sight, when in Faft (for I have difcourfed him over) 

 he is ignorant of the very Fundamentals, 'viz.. the 

 Anatomy of the Eye : And, as to Vilion, he knows 

 no more of it, nor of the Theory of Light and 

 Colours, than the Creatures I am treating of in this 

 Book. Indeed I muft own, he can couch a Cata- 

 raft and brufh the White of the Eye ( by the La- 

 tins called Tunica Adnata) with a Brufh made of a 

 few Rye or Barley-angs, (tied together in the 

 Middle with a little Silk ) when it is inflamed, and 

 by this Means cut afunder the fmall Capillary Blood- 

 VefTels, which are full and turgid in an Opthalmia 

 or Inflammation of the Eye, upon which the Eye 

 looks much better and clearer : But then, all this 

 While, fuch Operation is no new Thing ; for, it 

 has been a Pradice amongfl the French Surgeons,
