Ointments are also applied by inunction. A small quantity at a time should be rubbed in, using a circular motion. If an ointment is ordered to be applied where the skin is broken, the ointment should be spread upon gauze and applied without friction. Liniments are rubbed in in the same way as ointments. In many cases rubbing accomplishes more than the ointment or liniment itself, so that this part of the treatment must not be slighted. HOUSEHOLD MEDICINE CUPBOARD.--In every household a small cupboard is needed for medical and surgical supplies. Glass shelves are desirable, because they show when dirty and are easily cleaned, but a wooden cupboard can easily be lined with clean paper or white enamel cloth held in place with thumb tacks. Dirty, stained shelves should not be tolerated. The cupboard should be kept locked and the key put well out of the reach of children. In the cupboard should be kept medicines in daily use; they should not be paraded on family dinner tables. Poisonous drugs should have rough glass bottles and conspicuous labels. All medicine bottles should be kept well corked, since evaporation may take place and the remaining solution, by becoming stronger, may be dangerous to use in the ordinary amount. Pills and tablets sometimes deteriorate by standing, and may become so hard that they pass through the stomach and intestines without dissolving. It is best to buy drugs and surgical supplies in small quantities; when it is cheaper to buy more at a time the druggist should be asked whether they will deteriorate or not. Almost every family needs to keep on hand some cathartics, some disinfectants, some material for first aid, and a few simple appliances. Most families have certain other needs peculiar to themselves, and for those who live at a distance from drug stores a greater quantity and variety may be required. Elaborate equipment and extensive supplies of medicines are neither economical nor necessary for household use. Castor oil, Rochelle or other laxative salts, and two grain cascara tablets ordinarily constitute a sufficient supply of cathartics. The dose of castor oil is one or two teaspoonfuls for a baby up to a tablespoonful for an adult. Rochelle salts and seltzer aperient are given dissolved in water; the ordinary dose is from one to four teaspoonfuls. Seidlitz powders come in two packets, one white and one blue. The contents of the packets should first be dissolved in separate glasses each filled about a quarter full of water. One solution should then be poured into the other and the mixture taken while it is effervescing. Cascara tablets are generally given in one to ten grain doses.
