    not figured in any of them. The cases are also quite different. The fii'st is— Cornelius Cronin, who came to me here on the 6th of FebiTiaiy, in the present year. He came from Cork, where he had been educated for a schoolmaster. For eight or nine years, he says, he had studied. He was very fond of it, and had “ strained” his eyes. He had learnt several books of Euclid, as he informed me. For some years past his imperfect vision had obliged him to work as a labourer, and, seeking work, he had come to London. He had evi- dently read more than most labouring men, and was much better educated in every way than they generally are. He told me he had “ no permanent residence, but had been recently dwelling in St. Giles!” He had never sought any advice, but his sight being so very defective, and because he squinted, his friends sent him here. He was 25 years of age, slight and fair, in good health. His parents were not short-sighted, nor had they any defects of vision, but they had not had the education he had had. When he was 14 years old his sight began to fail, and to get shorter and shorter. In three or four years afteiwvards he had to give up reading and wiiting. The external strabismus of the right eye began about this time ; it was of about three lines when I measured its extent. Since that time his sight has been gi-adually getting worse and worse. With the right eye he could hardly spell No. 16 of Jager’s types, at any distance or in any dii'ection. With the other he could, at six inches distance at farthest, read No. 1 fluently. So that I suppose he meant by his fading sight that it was so gradually in the right eye tested separately, and that with the left eye he could only, as at present, see objects brought nearer and nearer to the eye. As a boy he had kept sheep, and he could make them out at a distance like any one else. He had sometimes seen muscae, like strings of pearls, when looking at a light. He had seen no flashes of light; he had felt no pain or any sensation of tension
