In this examinationit seems desirable, first, to make the examinationif possible without rotation of the wrist; andsecond, that the plate should be on the radialrather than the ulnar side. Both are very con-veniently provided for by the device here illus-trated, which can be used on a wide chair-arm,as shown here, or by placing it upon a slot between the base and the upright servesto hold the plate in the vertical position.(Bowen) 184 HANDS
