Taylor Maximum Thermometer

<< >>
This mercury-in-glass thermometer is so designed that an air bubble separates a small bit of mercury from the main part of the column. When the instrument is mounted horizontally, the detached mercury remains in place when the rest of the column falls, thereby indicating the maximum temperature. John Phillips, an English geologist, introduced the form at the 1832 meeting of the British Association for the Advancement of Science.
The bulb is spherical. The tube has a milk white back; the scale on the front extends from -30 to +110, graduated by degrees, The supporting metal plate is marked "Taylor, Rochester, N.Y." and "U.S.W.B." and "No.43191" and "MAXIMUM."
