Mercury-in-glass thermometer with a milk white tube. The supporting brass plate reads, at top, “WILLIAMS, BROWN / & EARLE / PHILADELPHIA, PA.” and at bottom “Chas. Wilder Co. / Troy, N.Y.” It is graduated from -32 to +120 degrees, with indications for “FREEZ/ING,” “TEMPE/RATE,” “SUMR/HEAT,” and “BLOOD/HEAT.” Williams, Brown & Earle manufactured and marketed mathematical and optical instruments. The Chas. Wilder Co., which had long been manufacturing thermometers in New Hampshire, was acquired by W. & L. E. Gurley in 1905 and moved to Troy, New York.
