In a nearly pure state carbonic acid is heavier thanair, and where the air is of an even temperature, it willoccupy the lower part of the room near the floor, (^wingto the fact, however, that in most c-ases the air is Avarmer in VENTILATION. 95 some parts of the room than in othere, it is not at allimprobable that the carbonic acid diffiises itself throughoutthe room. The problem then is to remove this vitiated air, andMipply its place with pure air, by not subjecting- the occii-p;ints to cold draughts. To secure this end, ample meansof entrance and escape of air must be Fig. I. The best means which can be provided, is the open fireor grate for escape, as currents setting up the flue willchange the air very quickly if means of entrance areprovided l)y an open transom, a window lowered at thetop, or other means.

Fasten a neat piece of woodfrom 3 to 5 inches wide inside the bottom sash, fittingit tightly at ends and bottom, and leave it far enough awayso that the sash will move up and down with ease, and ifthere is half an inch between, it will only act the better. When the lower sash is raised, the air rushes into theroom between the piece of wood set in and the sash, andalso at middle between the two sash, as shown by thearrows pointing upward. It will be seen that the piece setin prevents the air from coming in and striking theoccupants as a direct draught, as when the air strikes theboard, it def
