Ther*mom"e*ter, n. Etym: [Thermo- + -meter: cf. F. thermomètre. See Thermal.] (Physics)
Definition: An instrument for measuring temperature, founded on the principle that changes of temperature in bodies are accompained by proportional changes in their volumes or dimensions.
Note: The thermometer usually consists of a glass tube of capillary bore, terminating in a bulb, and containing mercury or alcohol, which expanding or contracting according to the temperature to which it is exposed, indicates the degree of heat or cold by the amount of space occupied, as shown by the position of the top of the liquid column on a graduated scale. See Centigrade, Fahrenheit, and Réaumur. To reduce degrees Fahrenheit to degrees Centigrade, substract 32° and multiply by Air thermometer, Balance thermometer, etc. See under Air, Balance, etc.
– Metallic thermometer, a form of thermometer indicating changes of temperature by the expansion or contraction of rods or strips of metal.
– Register thermometer, or Self-registering thermometer, a thermometer that registers the maximum and minimum of temperature occurring in the interval of time between two consecutive settings of the instrument. A common form contains a bit of steel wire to be pushed before the column and left at the point of maximum temperature, or a slide of enamel, which is drawn back by the liquid, and left within it at the point of minimum temperature.

(noun) a member of a learned society; “he was elected a fellow of the American Physiological Association”
The Boston Tea Party helped popularize coffee in America. The hefty tea tax imposed on the colonies in 1773 resulted in America switching from tea to coffee. In the lead up to the Revolutionary War, it became patriotic to sip java instead of tea. The Civil War made the drink more pervasive. Coffee helped energize tired troops, and drinking it became an expression of freedom.
