F. hygrom[`e]tre.] (Physics)
An instrument for measuring the degree of moisture of the

[1913 Webster]
{Daniell's hygrometer}, a form of hygrometer consisting of a
bent glass tube terminating in two bulbs, the one covered
with muslin, the other of black glass, and containing
ether and a thermometer. Ether being poured on the muslin,
the black ball, cooled by the evaporation of the ether
within, is soon covered with dew; at this moment, the
inclosed thermometer gives the dew-point, and this,
compared with the reading of one in the air, determines
the humidity. Hygrometric
