Σελίδα 78 - It consists of a glass tube of uniform bore closed at A, and terminating at the other end in a bulb. The bulb contains mercury, which extends part of the way up the tube. The space between the mercury and the top of the tube is a vacuum. If the mercury in the instrument be subjected to an increase of heat, it expands and rises higher in the tube.
