received Sight by the formation of an artificial Pupil. 25 



She drove in a carriage, on the fourteenth day, four miles 

 on the Wandsworth road ; admired most the sky and the 

 fields, noticed the trees, and likewise the river Thames as she 

 crossed Vauxhall bridge. At this time it was bright sun- 

 shine, and she said something dazzled her when she looked 

 on the water. 



On the fifteenth day, being Sunday, she walked to a chapel 

 at some distance, and now evidently saw more distinctly, but 

 appeared more confused than when her sight was less perfect. 

 The people passing on the pavement startled her ; and once

 of my eye. All that I can say is, that I am sure, from what 

 I do see, a great change has taken place ; but I cannot de- 

 scribe what I feel."" 



Eighteen days after the last operation had been performed, 

 I attempted to ascertain by a few experiments her precise no- 

 tions of the colour, size, forms, position, motions and dis- 

 tances of external objects. As she could only see with one 

 eye, nothing could be ascertained respecting the question of 

 double vision. She evidently saw the difference of colours ; 

 that is, she received and was sensible of different impressions 

 from different colours. When pieces of paper one and a half 

 inch square, differently coloured, were presented to her, she 

 not only distinguished them at once from one another, but
