Weather compendium combining cistern mercury barometer, alcohol thermometer and thread hygrometer by George Graham, Fleet Street, London, 1739

This weather compendium combined a barometer, thermometer and hygrometer for measuring air pressure, temperature and humidity. The measure of humidity by the hygrometer depends on the stretching and shrinking of a piece of weighted whipcord, suspended inside the tapered wooden spindle.

The instrument was made by clock- and watchmaker George Graham (1673-1751); he has signed the dial of the central hygrometer. In addition to his status as a leading craftsman, Graham was also a Fellow of the Royal Society.

This weather compendium reflects a growing interest in observing and measuring meteorological phenomena during the 1700s. It was also a decorative item suitable for the home of a wealthy owner.
