An upright vulcanite rod at either extremity supportsthe wires connecting the Crookes tube with the terminals of the inductioncoil. It carries a travelling clamp to which the Crookes tube is attached.The chair used has a support for the head, to the upright of which twocurved arms are attached. One of these carries a pocket to receive thesensitive plate while the other serves as a support for the patients chin.By means of this arrangement the photographic plate can be broughtclosely into contact with the parts surrounding the eye to be X-rayed,and any movement of the patients head is effectually prevented by meansof the chin rest. The position of the anode of the focussing tube can bevaried at will by sliding the clamp along the graduated horizontal bar. PLATE XVIII.

If then the pointof the magnet be held against the centre of the cornea,and the current gradually increased by means of therheostat, the patient will, as a rule, suddenly give asharp cry of pain, and the metallic particle will be seento pass in front of the lens and to bulge the irisforwards. If, as sometimes happens, there is difficultyin attracting the foreign body, the operator must exer-cise patience and apply the current in such a way asto act on the metal by a series of jerks. The splinterreaches the aqueous by passing behind the lens andperforating the zonule; and, indeed, provided that thelens has escaped injury at the time of the accident, itis very seldom inju
