The clear front of the minimum stem is graduated every degree Fahrenheit from -65 to +132. The clear front of the other stem is graduated (but not numbered) every half degree Centigrade [?] from -37.5 to +51.5.

content: The thermometers are held in a Townsend support marked "Julien P. Friez & Sons." This support, which was introduced around 1905, enables the maximum thermometer to be released from its normal horizontal position and whirled rapidly around, and the minimum thermometer to be tilted so that the index can slide down to the end of the spirit column.
