£06 Account of two Children 



sule of the lens was found to be opaque, and the sight cori- 

 sequently imperfect. The eyes were not examined with re- 

 spect to their vision till the 13th of October, during which 

 period the bov leniained quiet in the hospital. On that day 

 the upper part of the pupil of the left eye had in some mea- 

 sure recovered its natural state, apd had become transpa- 

 rent, but the cicatrix in the cornea was more extensively 

 opaque than before. The light now was not distressing to 

 either eye, and when strong, he could readily discern a 

 white, red, or yellow colour, particularly when bright and 

 shining. The sun and other objects did not now seem to 

 touf;h his eyes as before, ihcy appeared to be at a short di- 

 slance froni'him. The eye which had been couched had 

 the most distinct vision of the two, but in both it was im- 

 perlect. The distance at which he saw best was five inches. 

 When the object was of a bright colour, and illuminated 

 bv a strong light, he could make out that it was flat and 

 broad ; and when one corner of a square substance was 

 pointed out to him, he saw it, and could find out the other, 

 ^vhich was at the end of the same side, but could not do 

 this under less favourable circumstances. When the four 

 corners of a while card were pointed out, and he had exa- 

 mined them, he seemed to know them : but when the op- 

 posite surface of the same card, which was yellow, was 

 placed before him, he could not tell whether it had corners 

 or not, so that he had not acquired any correct knowledge 

 of them, since he could not apply it to the next coloured 

 surface, whose form was exactly the same, with that, the 

 outline of which the eye had just been taught to trace. 



Case II. 



.John Salter, seven years of age, was admitted into St. 

 Ccorae's Hospital on the 1st of October, ISOG, under my 

 care, with cataracts in both eyes, which according to the 

 accounts of his relations had existed from his birth. 



After he was received into the hospital, the following cir- 

 cumstances were ascertained respecting his vision. The pu-' 

 pile contracted considerably when a lighted candJe -was 



placed
