I have said above that the face was not touched in the course of the rubbing. There are cases, however, in which massage of the head and face may be usefully practised. Some obstinate neuralgias are helped by it temporarily, and very often it is of use with other means to aid in a permanent cure. Many headaches of a passing character may be dissipated promptly by careful massage of the head or by downward stroking over the jugular veins at the sides of the neck to lessen the flow of blood into the cerebral vessels, where the pain is due to congestion or distention, and careful manipulation of the facial muscles in paralysis is of service in restoring loss of tone and improving their nutrition. It is worth adding here, as women patients frequently say that during their illness the hair has become thin or shown a great tendency to fall, that daily firm finger-tip massage of the head for ten or twelve minutes, followed by rubbing into the scalp of a small amount of a tonic, either a bland oil or if need be of some more stimulating material, will in a great majority of the instances where loss of hair is due to general ill-health perfectly restore its vigor and even its color. I am accustomed to pay a good deal of attention to the observations made on these and other points by practised manipulators, and I find that their daily familiarity with every detail of the color, warmth, and firmness of the tissues is of great use to me. A great deal of nonsense is talked and written as to the use and the usefulness of massage. The "professional rubber" not unnaturally makes a mystery of it, and patients talk foolishly about "magnetism" and "electricity;" but what is needed is a strong, warm, soft hand, directed by ordinary intelligence and instructed by practice; and this is the whole of the matter, except in the massage of such obscure conditions as need full knowledge of the anatomical relations and physiological functions of the parts to be rubbed. It is a fact that I have known country physicians who, desiring to use massage and not having a practitioner of it within reach, have themselves trained persons to do it, with considerable resultant success. It is not, perhaps, putting it too strongly to say that bad massage is better than none in those cases in which manipulation is needed. Very little harm can result from its use even by unskilled hands, provided that reasonable intelligence direct them. CHAPTER VII. ELECTRICITY. Electricity is the second means which I have made use of for the purpose of exercising muscles in persons at rest. It has also an additional value, of which I shall presently speak.
