Etymology: modern < Greek ὑγρο- hygro- comb. form + -σκοπος observing. French hygroscope.

An instrument which indicates (without accurately measuring) the degree of humidity of the air. Usually a device in which a vegetable or animal fibre (in Saussure's h., a human hair) which contracts with moisture, is made to move an index round a graduated scale as in the wheel barometer, or, in a familiar form, to make a small male or female figure emerge from a toy house.
