The effects of these drugs upon the skin may be divided into those relating to _color_, _sensation_ and _nutrition_. The sallow, cadaveric hue so often seen in advanced cases is partly due to discoloration by the biliary matters, which are not properly excreted by the liver, and partly to a condition of malnutrition, so often seen in persons suffering from cancerous disease. In case there is serious interference with the working of the kidneys, the sallow color becomes less distinct, diluted expresses it well, and it has an appearance more like that of old white marble. In this case the tissue feels doughy and “soggy,” and at points a pit made in the skin by the pressure of the finger remains. There is also puffiness under the eyelids and the eyes are bleared and watery. When there is no dropsy the skin is usually dry and harsh, although at times bathed with a cold, exhausting perspiration, the odor of which is oftentimes very offensive. A morphia or opium taker, previously ill-nourished, sometimes seems to improve, taking on flesh rapidly. The appearance, often best seen in the face, is very deceptive, and is, in the majority of instances, due to slight dropsy. It is sometimes seen a few weeks after these patients commence to use alcoholic stimulants, especially beer. It soon passes away, leaving them looking thinner and more miserable than before. In those cases where the habit has not progressed very far, the skin is usually made redder and coarser than natural, and is dotted here and there with pustules. In one case that I have recently had under my care, that of a young lady who had never used stimulants and who had only used morphia, and that subcutaneously, for seventeen months, a swollen and reddened condition of the nose, exactly like that seen in old drunkards, was present. Two weeks after the morphine was stopped the nose began to lessen in size and the color to disappear, and the condition was entirely cured at the end of three weeks. No local applications were used. Loss of elasticity of the skin is a common change. That nutrition is seriously interfered with is seen by this alteration, the loss of adipose tissue, the ill-balanced circulation, giving at one time coldness and paleness, at another flushing and undue warmth, and the variable secretion. A plump and well nourished person who commences the use of morphia loses those outlines of health caused by the proper development of the muscular system and normal distribution of fat beneath the skin. Face and form are both changed, and certainly for the worse. These changes are undoubtedly due to a double action of morphine; that on the alimentary canal preventing the proper digestion and assimilation of food, and that upon the nerves regulating the supply of blood that passes to the skin.
