20i Acconnt of two Children 



account of bis niollur, existed at the time of birth. From 

 earliest infancy he never stretched out his hand to catch at 

 any thins:, nor were his eyes directed to objects placed before 

 him, but rolled about in a verv vmnsual maimer, ahhoiigb 

 in other respects he was a lively child. The eyes were not 

 examined till he was six months old, and at that time the 

 catiracis were as distinct as when he was received into the 

 hospital. 



Pievious to an operation being pciFormed, the following 

 circumstances were ascertained respecting his vision. He 

 could distinguish light from darkness, and the light of the 

 sun from that of fire or candles : he said it was redder, and 

 more pleasant to look at, but lightning made a still stronger 

 impression on his eyes. All these dilfcrent lights he called 

 red. The sun appeared to him the size of his hat. The 

 candle flaine was larger than his finger, and smaller than his 

 arm. When he looked at the sun he said it appeared to 

 touch his eye. When a lighted candle was placed before 

 him both his eyes were directed towards it, and moved to- 

 gether. When it was at any nearer distance than 12 inch- 

 es, he said it touched his eves. When moved further off 

 he said it did not touch them ; and at l'2 inches it became in- 

 visible. 



On the 21st of July the operation of extracting the cry- 

 stalline lens was performed on the left eye. The capsule of 

 the lens was so very strong as to require some force to pe- 

 netrate it. When wounded, the contents, which were fluid, 

 rushed out with great violence. Light became very distress- 

 ing to his eye, and irave him pain. After allowing the 

 eve-lids to remain closed for a few minutes, and then open- 

 ing them, the pupil appeared clear, but he could not bear 

 exposure to light. On my asking bins what he had seen, he 

 suid, " Your head, which seemed to touch my eye:" but he 

 could not ti-li iis shape. He went to bed, and took an opi- 

 ate draught : the pain in his eve lasted about an hour, after 

 which he fell asleep. The whole of that day the light was 

 distressing to his eye, so that he could noi bear the least ex- 

 posure to it. 



On the 22d the eve-lids were opened to examine the eye.
