530 Mr. Wardrop’s case of a lady born blind, who 
others do. He would not consider the ideas of sight with 
reference to, or as having any connection with the idea of 
touch.” It may also be observed, that in the present case the 
blindness was more complete, and the period at which vision 
was acquired was much later in life, than in any instance 
which has hitherto been recorded. 
The lady, whose case forms the subject of this paper, was 
observed, during the first months of her infancy, to have 
something peculiar in the appearance of her eyes, and an unu- 
sual groping manner, which made her parents suspect that 
she had defective vision. When about six months old, she 
was placed under the care of a Parisian oculist, who performed 
an operation on both her eyes, with a view to afford her sight. 
The operation on the right eye was, however, followed by 
violent inflammation, and a collapse of the eye-ball, thus 
causing a complete destruction of the organ of vision. The 
operation on the left eye, though equally unsuccessful in 
attaining its object, was not followed by any alteration in 
the form or size of the globe. From the account stated by 
her friends, it was impossible to form any correct notion of 
the state of her eyes previous to the operations which were 
performed. It seems, however, extremely probable that the 
blindness, which was attempted to be remedied, had been 
produced by congenital cataracts, and that these operations 
had for their object the removal of the opaque lenses. 
From the above early period she had continued totally 
blind, being able merely to distinguish a very light from a 
very dark room, but without having the power to perceive 
even the situation of the window through which the light 
entered ; though in sunshine or in bright moonlight, she
