If a child is not in good health, it cannot keep up with its studies in school. It is more likely to contract any contagious disease, and it has not the proper chance to grow into a robust, healthy adult. If the child's teeth are decayed, it should be taken to a dentist at once. The teeth should be brushed after each meal, using a tooth brush and tooth powder. The following tooth powder is recommended: 2 oz. powdered precipitated chalk. ½ oz. powdered Castile soap, 1 dram powdered orris root. Thoroughly mix. This prescription can be filled by any druggist at a cost not to exceed fifteen cents. DEPARTMENT OF HEALTH CITY OF NEW YORK Instructions to Parents Regarding the Care of the Nose The physical examination of school children shows that in many instances they breathe through the mouth because they cannot breathe properly or sufficiently through the nose. This may be due to bad habits in regard to keeping the nose clean, or, in a majority of instances, to a growth which is known as "adenoids" and which stops up the back of the nose. In either case, the air is not breathed through the nose, and the child becomes what is known as a "mouth breather." Constant breathing through the mouth causes the child to become pale, restless in its sleep and dull in its actions. The child often speaks as though it had a cold in the head. Frequently there is an almost constant discharge from the nose. Mouth breathing renders a child especially liable to contract tuberculosis and other infectious diseases; in fact, the child has very little resistance to disease of any kind. Every child should be given a handkerchief, and be taught to thoroughly blow the nose several times each day. If, after doing this regularly, the child is still unable to breathe properly through the nose, it is probable that an adenoid growth is present. Such children should be taken to the family physician or to a dispensary for further advice and treatment. Do not wait too long in the hope that the child will outgrow the condition, for the effect of adenoid growths persisting throughout childhood may injure the person for life. Have your child's throat and nose examined one month after measles, scarlet fever, or diphtheria.

The following directions will cure the condition: Mix one-half pint of sweet oil and one-half pint of kerosene oil. Shake the mixture well and saturate the hair with the mixture.
