This is a glass thermometer filled with a red liquid that the manufacturer termed “Permacolor or Mercolor.” The tube has a milk-white back and a front configured so as to magnify the liquid column. The supporting metal plate is marked, at top, “Tycos / ROCHESTER, N.Y. U.S.A. / TORONTO, CANADA.” This is graduated from 26 to 102 degrees Fahrenheit, and provided with a metal bulb guard. This is mounted, in turn, on a wood board. The Taylor Instrument Companies donated it to the Smithsonian in 1923. It was apparently made in 1913, the year Taylor opened an office in Toronto.
