The other defect, at times quite disagreeable, was that the handleof the instrument would often become so greatly heated as to burnthe hand of the operator, and to prevent sometimes his turning thecontact screw to break the electrical current. Examination soonshowed that this was due to bad contact. Recognizing more and more during two years work withFreudenbergs instrument the drawbacks referred to, and especiallyfeeling the need of blades of different size, th writer finally con- A NEW BOTTINI INCISOR—Young. 153 suited the Kny-Scheerer Company of New York during April,1901, with reference to the construction of an instrument whichwould, if possible, fill all the requirements. After considerable ex-perimentation we have produced, we believe, a satisfactory instru-ment, the construction of which is thoroughly explained by theaccompanying cuts. As seen in the illustrations, the form of Freudenbergs instru-ment is adhered to (Fig. i), the only changes being in its havingfour in
