A little charcoal mixed with clear water thrown into a sink will disinfect and deodorize it. Chloride of lime and carbolic acid considerably diluted, if applied in a liquid form, are good disinfectants, and carbolic powder--a pink powder with a smell resembling tar, and sold at about 2d. per lb.--is both useful and effective. The air of a bedroom may be pleasantly sweetened by throwing some ground coffee on a fire shovel previously heated.
