Apparatus.— The apparatus provided is a constant volumeair thermometer consisting of a thin glass, spherical (or cylin-drical) bulb A blown atthe end of a capillarytube B, which is bent inthe manner shown infigure 5. The otherend of the capillary isconnected to a glasstube C, about one centi-meter in diameter whichis sealed into a threeway steel stop-cock S,by means of wax. Thiscock is connected byheavy rubber pressuretubing to a second glasstube D, of the same in-ternal diameter as C and D are fixedto movable slides whichcan be clamped at anydesired height along thevertical support height of D maybe further adjusted bymeans of a fine adjust-ing screw E.
