IMPROVED. 107 



when I read it. But when I told the Do£lor that 

 he had puzzled me, he faid he was glad on it, for 

 he did not write in order to be underitood, fo that 

 he had gained his Point. But for Fear of naufeate- 

 ing the Reader too much with dwelling upon this 

 Man of Ability, I ^11 proceed. 



The fecond Humour is the Crxjlalllne. It lies zd. The 

 immediately next to the Aqueous, behind the C/t;^^,c:iyftalline. 

 oppofite to the Pupil or Sight of the Eye, nearer

 that he has negledled the Peruf^l even of fome of 

 our own Nation, particularly Dr. Kennedy : I fay, 

 if T-—r the Oculift had per u fed this Author, or 

 ( if he could not underftand him ) have got fome
