"A bulb of liquid is placed in the base of the glass graduated tube. As temperature increases, the volume of the liquid increases and it expands up the tube where its level is read on the graduated scale." —Quackenbos 1859

"Used to compare the temperature between two environments. As the temperature in one bulb increases, the liquid reading changes according to the air expanding within the bulb. If both bulbs are the same temperature, the scale measures zero." —Quackenbos 1859

"The whole length of the tube of the wheel barometer, from C to A, is 34 or 35 inches, and it is filled with mercury, as usual. The mercury rises in the short leg to the point a, where there is a small piece of glass floating on its surface, to which there is attached a silk string, passing over the pulley p. To the axis of the pulley is fixed an index, or hand, and behind this is a graduated circle, as seen in the figure. It is obvious, that a very slight variation in the height of the mercury at o, will be indicated by a considerable motion of the index, and thus changes in the weight of the atmosphere, hardly perceptible by the common barometer, will become quite apparent by this." —Comstock, 1850
