Not illustrated. 1916 Excerpt: ...on the enclosed gas is regulated by raising or lowering the open tube. The value of this pressure may be determined from the barometer-reading and the difference in the levels of the mercury on the two sides of the frame. Each time before taking the readings, the volume of the air in the bulb is made the same by bringing the mercury meniscus to the level of the wire point inside the glass tube attached to the bulb. Caution: --The mercury oh the bulb side should always be lowered some distance before changing to a lower temperature. Be especially careful to do this before removing the steam-bath when you have taken a reading at the boiling point; otherwise, on cooling, the mercury will run into the bulb. Do not hurry in taking the readings after changing the temperature, but wait until the meniscus set at the wire-point remains stationary. (a) Without any bath in the reservoir, while all is at the room-temperature, bring the mercury to the wire point and determine the difference in level of the mercury columns. Record the room-temperature, and the barometer-reading. (b) After having lowered the mercury on the bulb side, surround the bulb with shaved ice, and then determine the pressure with the menicus at the wire point. The temperature may be taken as 0C. Melt the ice with warm water, and then make a series of determinations of the pressure when the water in the vessel is successively at a temperature of (approximately) 10, 20, 30, 45, 60, and 80C. Remove the water-bath, substitute a steam-bath in its place, and make another determination. The temperature of the steam-bath may be found by determining the boiling point of water from the known atmospheric pressure (see Tables). Arrange all observations in tabular form. (c) Plot on coordinate paper the results ..
