Similarprecautions to those adopt-ed in the Austrian fuseWM/mtf/y/M${ are taken in making and gauging the break in the conducting wire, and in fillingin the composition, which is the same as that used by BaronYon Ebner. The opening is stopped with a cork, shown at(i) in sketch. Of these two last forms the Austrian seems
