I advise that it be given in all cases of sore throat, for although it is not so important a remedy in all these cases, it will very generally be useful in a greater or less degree, and as the sore throat is usually the first thing complained of in diphtheria, its early application is thereby assured. A very small dose will suffice, but there is no objection to taking two or three grains for a dose every 4 hours, except the disagreeable taste. I advise that it be taken alone, and not covered up, as I believe that it acts locally perhaps directly upon the organism or germ that is the cause of the disease. I have not, however, relied exclusively upon the one medicine, but have always directed that they should give about a teaspoonful of the saturated solution of chlorate of potash every hour, and that they keep kerosene applied on the outside of the throat or neck. Give plenty of milk and other nourishing diet, and but little other medicine is usually required. The SANGUINARIA (bloodroot) POWDER is properly given in other cases besides diphtheria. A small dose given three times a day is not only a good worm medicine, but will prevent the subsequent developement and growth and multiplication of worms for some time. It is also a cure for a cough that is dependent on an irritated state of the fauces. Three grains taken after each meal is a good remedy in chlorosis or suppression of the menses. In these cases it can be taken covered up in wafers or in rice paper, thereby avoiding the bitter taste. ACONITE should be kept in the house, and very small doses given in cases where there is a little feverishness, and no marked symptoms of disease. It is useful when there is an ordinary cold, and may be given two drops of the tincture in half a glass of water, one teaspoonful every hour. These small doses may be given to a little child, and yet they have some effect upon older persons. ORDINARY COLDS, however, require more efficient treatment, and I often direct the following: A teaspoonful ginger, a teaspoonful cream of tartar, and three large teaspoonfuls of sugar in a small glass of water, to be drank as one draught after being stirred. Heat the feet and keep them warm especially at night. The combination of ginger, cream of tartar, &c., opens all the secretions so that the lungs, liver, bowels, skin, and kidneys act in a natural manner, and there is immediate benefit.
