532 Mr. Wardrop’s case of a lady born blind , who 
introduced a very small needle through the cornea, passing it 
also through the centre of the iris ; but I could not destroy 
any of the adhesions which had shut up the pupillar opening. 
After this operation she said she could distinguish more light, 
but she could perceive neither forms nor colours. The 
result of this first attempt justified the favourable views en-

at this time was consulted, coincided with me in this opinion.

was very imperfect ; for although there was an incision made 
in the iris, some opaque matter lay behind this opening, which 
must have greatly obstructed the entrance of light. 
On the 17th of February, a third operation was performed, 
which consisted in still further enlarging the opening in the

at my house, she returned home in a carriage, with her eye 
covered only with a loose piece of silk, and the first thing 
she noticed was a hackney coach passing, when she ex-

In the course of the evening she requested her brother to
