#S CASK OF A YOUNG LADY, $C. 



preceding pages, in the prefence -of Mr. Scott, furgeoa, iii St. 

 AlbanVftreet. The operation gave her no pain ; and, in the 

 courfeofa few days, the opacity was evidently dim inifhed, 

 particularly in the right eye, the patient diicovering the co- 

 lour of Objects more plainly than before, but being ftill unable 

 to diftinguifh their figure. At the end of a month, finding no 

 further improvement in her vifion, it appeared to me moll 

 probable that the remaining opacity was fituated in the cap- 

 iules. I therefore determined to extract either a part or the 

 whole of each of them. The incifions of the cornea were 

 made in the u.fual manner ; after which, I punctured the an- 

 terior parts of both the capfules with the fharp end of a gold 

 curette. The punctures became immediately tranfparent, 

 without affo.rdmgjin iflfue to the liquor Meibomii, or any other 

 humjmr. from hence it feems evident, that nothing was con- 

 tained within the capfules, or, in other words, that the cryftal- 

 line humours w^ere abforbed; and it appears to me highly 

 probable, that: their abforption had been occalioned by the 

 previous operation of puncturing their capfules with the 

 couching needle. J dilated the new punclures with the end 

 of the curette ; and afterwards, being Itill afraid that the 

 apertures in the capfules might not be large enough to admit 

 a fufficient number of the rays of light, I removed a portion 

 of each of them with a fmall forceps. This was accompliflied 

 in the left eye, without occalioning the difcharge of any part 

 of the vitreous humour ; and, in the right, the quantity of this 

 humour that came away was very fmall. In the courfe of a 

 week, the inflammation that followed the operation was 

 nearly removed ; a large portion of both pupils was quite 

 clear ; and the young lady diftinguifhed objects with quicknefs 

 and precifion.
