    • n pyrometer An instrument, in the form of a simple metallic bar, employed by Muschenbroek, about 1730, for measuring the changes produced in the dimensions of solid bodies by the application of heat. The name is now applied, however, to any instrument the object of which is to measure all gradations of temperature above those that can be indicated by the mercurial thermometer. Wedgwood's pyrometer, the first which came into extensive use, was employed by him for testing the heat of his pottery- and porcelain - kilns, and depended on the property of clay to contract on exposure to heat. Many different modes have been proposed or actually employed for measuring high temperatures: as by contraction, as in Wedgwood's

No doubt the figures mounted high--
She sighed and said she could not roam,
Then pitt (i) ed me with cherry pie.
