received sight by the formation of an artificial pupil. 537 
notions 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 
gave a decided preference to some colours, liking yellow 
most, and then pale pink. It may be here mentioned, that 
when desirous of examining an object, she had considerable 
difficulty in directing her eye to it, and finding out its position, 
moving her hand as well as her eye in various directions, as 
a person when blind-folded, or in the dark, gropes with his 
hands for what he wishes to touch. She also distinguished a 
large from a small object, when they were both held up 
before her for comparison. She said she saw different forms 
in various objects which were shown to her. On asking what 
she meant by different forms, such as long, round and square, 
and desiring her to draw with her finger these forms on her 
other hand, and then presenting to her eye the respective 
forms, she pointed to them exactly : she not only distin- 
guished small from large objects, but knew what was meant 
by above and below ; to prove which, a figure drawn with ink 
was placed before her eye, having one end broad, and the 
other narrow, and she saw the positions as they really were, 
and not inverted. She could also perceive motions ,* for when 
a glass of water was placed on the table before her, on 
approaching her hand near it, it was moved quickly to a 
greater distance, upon which she immediately said, “ You 
move it ; you take it away.”
