Irido-cyclitis occurred, resulting in total An instrument devised for the purpose of ex-amining ones own fundus. Various forms have been invented, butthe first successful one was constructed by Coccius; since then Hey-mann, Giraud-Teulon, Zehender, Gould and others have describeddifferent instruments. One of the simplest and best is that of Giraud-Teulon. Its action is explained by the accompanying Giraud-Teulons Auto-ophthalmoscope. The instrument consists of two plane mirrors, m m, inclined to oneanother at an angle of 90°, and placed in front of the observer. Aconcave mirror (c c) is held obliquely before the left eye (g), sothat the rays from a flame (F) are reflected on to m, and thence on tom, which will reflect them into the right eye (d). A double-convexlens, 1, is placed between d and m, by which an inverted aerialimage of A is formed, which is situated in reality at a betweenthe two mirrors, but which will appear to g to be situated beyondthe mirror, m, at a. In fact the rays emanating from d, instead ofpassing straight on, are bent twice at a right angle, and broughtback to g, without having undergone any change in their relativepositions. Another method is described by E. Wessley (Centralhl. f. prakt. AUTO-OPHTHALMOSCOPE 713 Avgenheilk., Oct
