It is quite 'Common to be told by the patient that he saw a stone as big as his fist strike him on the eye and fly off*, and then to find a piece of iron in the depths of the eyeball. The illusion may be explained by the fact that the patient sees the foreign body entoptrically magnified during its pas- .sage through the vitreous, and projects its flight outward. In all such cases, therefore, it is of the utmost impor- tance to make a thorough search for particles of iron, and to remove the intruder as quickly as possible. By ])rompt removal the eye may be saved even when the particle of iron is from a hoe; but every minute of delay makes the prog- nosis more doubtful. The best method to pursue is the one described on p. 175. GLAUCOMA.

I. Primary Glaucoma. Primary glaucoma is spontaneous, usually bilateral, and may be acute or chronic, with a varying increase of intra- ocular tension. In the acute form we have all the ex- ternal signs of inflamniation : Redness, pain, edema of the conjunctiva and iris; in the chronic form these arc absent most or all of the time. Primary glaucoma is therefore subdivided into inflammatory and non-infiammatory or simple f/Iaucoma, al though the latter may at any time change to the inflammatory form.
