Kellv instrument when the sphincter vesicae will not retain theinjected fluid, when the injected fluid becomes turbid and bloody,and when the bladder is so contracted that it fails to distend and ureteral exploration in women, owing to the shortnessand dilatability of the urethra, may be accomplished satisfactorily bymeans of the simple Kelly cystoscope already described. In examin-ations of the male urethra the prismatic electroscope, on account ofits magnifying power and the greater distance of the field of inspec-tion from the eye, is indispensable. The Kelly instrument has the advantage over the electrical cysto-scope of not exposing the bladder to burns; and of giving a moreaccessible field for topical applications. V
