Buttermilk.—Where we prescribe this, either for drinking or for external use in poultices or bathing, it is very important it should be pure and fresh. If kept too long, it causes often terrible pain when applied to eruptive sores. There must be no "watering" or doctoring with cream of tartar, if good results are desired. If the milk be too long kept, and cannot be had fresh, it may be mixed with a little sweet milk and all churned well together. Then it may be used. If still painful, mix again with more sweet milk. To soak diseased skin in good fresh buttermilk is so powerful a means of cure, that to procure it a good deal of trouble is well spent. It is also invaluable as a daily drink for regulating the bowels, and maintaining health. Sterilise all sweet milk used.

If buttermilk cannot be had, acetic acid or vinegar, or the juice of lemons, may be mixed with sweet milk or even water, until the mixture attains about the usual sourness of buttermilk. This makes an efficient substitute.

Buttermilk Poultice.—Boiled potatoes beaten up with fresh buttermilk make an excellent poultice for all eruptive sores, scabbed heads, and heated skin affections. After these always apply soap lather (see Lather). If buttermilk cannot be had, use acetic acid or vinegar, as above.

Cancer.—Swellings in the breast often arouse fear of cancer, but are generally very simple affairs and easily yield to treatment as in article Breast, Swelling in. If not, we should chill the diseased growth so as to arrest it. Now this, as we have proved, may be effectually done, and the sorely tried patient may be saved a world of pain, and perhaps cured. We have seen more than one apparently desperate case, even where the breast had been cut off and the evil was again showing itself, in which effective cooling arrested the growth and saved the sufferer. When a growth of this kind has gone a certain length, there is severe pain. The cooling removes this, and secures the patient unspeakably precious rest without narcotics. But this is not all: it puts an effectual stop to the swelling. If the case has not gone very far, the swelling falls, and may disappear; but even when it has gone too far for this, the disease is stayed, and all symptoms of it are lessened. All swelling but the actual separate growth is removed. For instance, when the swelling has passed from the breast into the armpit it has been dispelled, and entirely confined to the actual substance of the tumour. This is managed simply by the persistent and vigorous use of cold towels. They must be large enough to allow of fourfold covering of the whole breast. They are wrung out of cold water at first, and, if possible, cooled with ice instead of being wrung out after. One at a time is kindly pressed all round and over the swollen breast. It is heated in one or two minutes, and must be changed. The second is pressed round and all over the breast in the same way. It is soon heated too, but you may have three of them in a circle, and if you have a bit of ice for those that are cooling, you have cold enough. Some would put on an ice-bag, and let it lie, but we have never been able to advise this, as it is very apt to destroy the outer skin by too severe cold. This treatment requires work—no doubt of that—but the effects are well worth it.

When the cooling treatment, given twice a day, or oftener if it can be without discomfort, has reduced the swelling and put back the tumour, till it may fairly be regarded as capable of absorption, it will be well to try the effect of hot fomentation by bathing (see Breast, Swelling in). This will not do harm, but good, if it is only used so far as to try whether the stage for hot treatment has been reached. If the hot bathing is agreeable, and instead of causing pain, rather soothes and comforts, it may be strongly tried. But this will be only if the effectual cooling has put back the disease, or if it has been really mastered. So long as it shows a tendency to increase, it will be well to continue the cooling.

Even if it be not possible to remove the disease, its progress may be arrested, and it may be rendered dormant for the rest of life. We know persons sent off to die with growths who are now quite well and have been so for many years, with these growths only rendered dormant. Even if this is not possible, it may be that we render the growth so slow that it shall come to nothing important in the remainder of even a long life. We should never hesitate to do our utmost in any case.

Besides the local treatment given above, vital action in the whole bodily system has to be increased on a definite line. This is the ripening and removing used-up substance from the body. It is sluggish ripening of substance to which we trace the morbid living growth; that sluggishness must be overcome. The first and most important means for this is fresher air for the lungs. The seaside home, if there are no drugs or drinks prescribed in ignorance, nor any other drawback, will be found of immense value here.

Next in importance to fresh air is pure distilled water. It should be used both in preparing food and for drinking. This constant use of distilled water is one of the most important remedies in cases of cancer. Comfortable clothing (see Underwear) should be worn by night and day, and damp avoided. The food should be such as can be most easily assimilated. Whole wheaten meal in various forms and pure water work wonders on "hopeless cases."

But when all these conditions have been supplied, "pack" the whole body at eight o'clock at night in cloths lightly wrung out of hot vinegar and water, half and half, and covering these with dry sheets and blankets, give the patient an hour in this "pack." On taking out of this, rub gently all over with hot olive oil, dry that off and put to bed. In the morning, at half-past seven or so, pack in a soapy blanket for an hour, then sponge with vinegar and rub with oil. Take a stick of good liquorice, with half an ounce of senna leaves, and put these in a quart of water, boil the whole down to a pint, giving a teaspoonful of this in a little hot water three times a day.
