|Label||This thermometer came to the APS along with the papers of Charles Moore Wheatley, a natural scientist and mine owner. Wheatley, a member of the APS, was born in England in 1822 and emigrated to the United States as a child. Interested in geology, paleontology, and mineralogy at a young age, as an adult he managed mines in Pennsylvania and worked in mineralogical exploration before opening his own mine near Phoenixville, Pennsylvania. While there is no information about the function of this particular thermometer, thermometers and barometers were both used at mining sites to monitor conditions in the mines, to ascertain the temperature of the mine and likelihood of explosion, and in the refining of metals.|
