    with an outer case of wood lined The safe is divided into cham- cooled and also the ice.—[U.K. W. E. Newton. Proposes to preserve fruit and vegetables by exposing the same to a temperature “ nearly approaching the freezing “ point of water, but which will not actually freeze them.” The object is attained by means of a kind of ice-house, properly constructed with non-conducting sides, &c., the ice used for cooling being placed in an upper compartment, and the fruit, &c., to be preserved, below.—[U.K. 1846, September 17.
