A bstract A volumcnometer of improved design has been developed for measuring the solid volumes of specimens varying in size up to that of standard refractory bricks. The chief feature of the new design is the use of a closed‐cistern, altitude‐type mercurial barometer to replace the simple manometer previously used. The barometer is de signed for use in a constant temperature room (21.1°C.) where the acceleration of gravity is 980.1 cm. per sec. 2 . Under these conditions, pressure readings are auto matically corrected to standard conditions. A vernier permits rapid readings to 0.1 mm. of mercury.
