girls. FORGET-ME-NOT.--1. We are much pleased to hear that your daughter’s hair has improved from using the wash. Continue to wash her hair once a week with the boracic acid. After having washed and dried her hair rub a little sulphur ointment into the scalp. It is useless to apply the ointment to the hair itself.--2. Your second question is rather difficult to answer. Your daughter is certainly suffering from blepharitis--a most intractable disease. The treatment that you are carrying out is the best we know; but we would suggest that she should bathe her eyes twice a day in warm solution of bicarbonate of soda (5 grains to the ounce). In your daughter’s case it is probable that something more than lotions and ointments is needed. It is well worth your while to consult an ophthalmic surgeon. The longer the disease has lasted the more difficult it is to cure. You should attend to the general health of your daughter and feed her well. HESPERUS.--Do not feed your children on condensed milk alone. If you continue to do so you will have five rickety children to look after. Cow’s milk diluted with fresh barley water is the best artificial food (excluding asses’ milk which is very expensive) for infants. The elder children may be allowed to eat much the same as you do yourself. It is always well to let children have plenty of milk even when they can digest ordinary adult diet. Give the child with “weak legs” a little cream with her milk. URSULA.--1. A pale swollen tongue is a symptom of many complaints. Usually it denotes indigestion, constipation or anæmia. It is constantly present in atonic and amylaceous dyspepsia.--2. The incubation period of mumps is rather variable. It is usually from two to three weeks. ROLY POLY.--1. The usual expedient adopted to cure children from the habit of biting their nails is to dip their fingers into tincture of aloes or solution of alum. If you cannot cure yourself of the habit by rational means, you might try one of these measures; but surely a girl of seventeen can restrain herself from such a habit. It is a very silly trick to get accustomed to, for it interferes with the proper development of the nails, and, consequently, spoils the look of the hands.--2. Clean your nails well and rub a very little lanoline into them. JANET.--Go to an ophthalmic surgeon and get your eyes seen to at once. If taken in time squint is usually cured without operation.
