are used in chemical laboratories for a number of purposes, and are of three sorts. Triangular ones are used both for marking glass and assisting in the breaking of frlass tubing by partially filing through the surface and then applying pressure to the weakened part. The round ones arc chiefly employed for filing smooth the holes made in corks by borers, or for enlarging them whilst flat files are used for smoothing or reducing the diameter of corks and taking the ragged edges off the ends of glass tubes, etc.
