Eye injuries and their treatment . hich can be raised or lowered) firmly fixed to a heavy base,and connected by a circular hinge joint with a horizontal bar graduated asa centimetre and millimetre scale running on either side of a centralpoint marked zero. 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 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 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 PENETRATING WOUNDS 87 the splinter may be most readily extracted by enlargingthe rent, if necessary, and applying the point of themagnet to its lips; but as a general rule the eye willbe damaged less if the magnet be used in such a wayas to draw the foreign body to the aqueous chamberalong the path of least resistance. 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
