 CONJUNCTIVITIS, 



Caused by a Llow, as the stroke of a "whip, bites of insects, 

 common cold, or the lodgment of a foreign body. 



Inflammation of the superficial structures of the eye is mam-^ 

 fested by clos\ire of the eyelids, swelling of them, and increased 

 secretion of tears, which fio'w down the cheeks, scalding the skin 

 to such an extent that it soon becomes divested of hair at every 

 part over which the tears floAv, and the eye is retracted and 

 partly coA'^ered by the membrana nictitans. If the eyelids be 

 turned up, the conjunctiva will be found in a state of extreme 

 congestion, and covered by a number of red streaks. The pro- 

 gress of inflammation, as seen in the eye, when conjunctivitia 

 proceeds perhaps from a simple catarrhal affection, is yery 

 instructive. First of all, there is a slight weeping, and if one 

 may judge from actual personal feeling and experience, there ia 

 a sense of irritation, as if a foreign body were in the eye. The 

 surface of the cornea is dim and blue-looking, and vascularity is 

 seen only at its margin and the parts external to it, because it 

 possesses no vessels in its intimate structure, and the gradually 

 increasing opacity is due to exudation (as already explained) 

 within its ultimate cellular stinicture.
