Chamber, in building, a part of a lodging, or a partition of an apartment, usually intended for the accommodation of beds. We can-not enter into an explanation of Privy Chamber, Chambers of Jus-tice, Commerce, etc. as these are unconnected with our purpose : hence we shall only observe, that we have already given a few direc-tions for correcting a vitiated at-mosphere, particularly that of bed-chambers (see Air, p. 22 ; and Bed-room, p. 211); so that we may conclude this article with a short account of a curious mode of cooling the air in rooms, frequently practised by the Germans.

In the hot days of summer, es-pecially in houses exposed to the meridian sun, a capacious vessel idled with cold water is placed in the middle of a room ; and a few green branches (or as many as it will hold), of a vigorous lime, birch, or willow-tree, are plunged with their lower ends into the fluid. By this easy expedient, the apartment will, in a short time, be rendered much cooler; as the evaporation of water produces this desirable effect, in sultry weather, without any detriment to health. Besides, there can be no doubt, that the exhala-tion of green plants, under the. influence of the solar rays, greatly tends to purify the air ; and conse quently deserves every attention of persons liable to pulmonary, or other complaints, in which the organs of respiration are affected.
