    blesome tension of the eyes, were the immediate conse- quences of this occurrence. These would soon have disappeared, if the sufferer had not on the following morning exposed himself, in the same manner, to the rays of the suu. On the next day he was attacked with a violent ophthalmia, which for a time resisted with great obstinacy all curative measures; and finally left the eyes with a considerable debility and such a predisposition to inflammation, that for a very long time after he was un- able to bear the slightest wind, or the least heating of the body, without suffering from red, weak, and watery eyes. Another case in point is related by Himly, from a small tract entitled Fabric of the Eye.* A lawyer took lodgings in Pall Mall. The front windows of the house faced the street, and were exposed to the full blaze of the meridian sun ; while the back room, having no opening but into a small, close yard, surrounded by high walls, was very dark. In this room he performed all his labours and studies; but came into the other to his breakfast and dinner. His sight soon became weak; and at last, he was troubled with a continual pain in the eye-balls. He tried glasses of various kinds, and sought counsel of various oculists, but tvithout obtaining relief. At last it occurred to him, that the frequent alternation of light, in going and coming suddenly from the darki study into the bright blaze of the dining-room, might be the cause of his disorder. He immediately hired other lodgings in a different quarter of the city, more favoura- bly situated in regard to the light; and discontinued reading and writing for a while in the evening. This was sufficient, and soon effected a cure. These cases are very instructive. They show the great danger of sudden changes from weak to strong, * Himly, Ophthalmologische Beobachtungen und Untersuchun- gen, oder Beytrage zur richtigen Kenntniss and Behandlung der Augen im gesunden und kranken Zustande.
