If opening at top, it istroublesome of access and difficultto make its space available. If ithave doors at the sides, the coldair flows out every time it isopened; and if the ice is placedat the bottom, there is no circu-lation of air or means of coolingthe upper space. A. S. Ltmax, of N. Y., has obviated these defects bya newly devised arrangement (Fig. 107). The ice is placed in an upperchamber over a grate opening to the flue a, through which, ice-coldair constantly falls. The body of the refrigerator is occupied by threedrawers, I c d, c being represented as partially withdrawn. The coldair fills these drawers, and as it becomes slightly wanner is pressed.

It descends again throngh the flue, tlie temperature of thewhole refrigerator being thus kept down nearly to freezing. Thewaste water is caught at g. The arrangement of drawers makes thewhole space available, and is as convenient as a common one is partially withdrawn, as at f, the air in, it being heavierthan that of the room, does not escape, while the circulation of air con-tinues within. There is also a twofold means of purifying the f there is a filter consisting of a wire-gauze box, through whichthe air passes and is disinfected.
