Thermometer

(thur-mom' -et-er). An instrument for measuring the ini of heat, consisting of a reservoir of mercui alcohol expanding into a vacuous capillary tube, tin intensity being measured by the length of the columi of mercury. T., Centigrade, one in which freezing-point is at and the boiling-point at 100°. T., Clinical, a thin-bulbed, self-registering thermom eter for ascertaining the bodily temperature. T. Fahrenheit, one in which the interval between ing and boiling is divided into 180 equal pail. called a degree, the zero-point being 32 degn divisions below the freezing of water. T., Reaumur, one in which the freezing-point is o°, and tin boiling-point To convert the registration 1 thermometer into that of another the following formulae are useful Let F=- No. of degrees Fahrenheit. " C= " " Centigrade. " r= " " Reaumur. Then to convert Fahr. into Cent. Cent, into Fahr. Fahr. into Reaiitn. Reaum. into Fahr. 33 Surface, a +thermometer for registering th. temperature of any portion of the body. Si page for Table of Comparison of Thermometers. 9/?
