Wonderful is the way in which people will go upon the slightest observation, or often upon no observation at all, or upon some _saw_ which the world's experience, if it had any, would have pronounced utterly false long ago. I have known patients dying of sheer pain, exhaustion, and want of sleep, from one of the most lingering and painful diseases known, preserve, till within a few days of death, not only the healthy colour of the cheek, but the mottled appearance of a robust child. And scores of times have I heard these unfortunate creatures assailed with, "I am glad to see you looking so well." "I see no reason why you should not live till ninety years of age." "Why don't you take a little more exercise and amusement?" with all the other commonplaces with which we are so familiar. There is, unquestionably, a physiognomy of disease. Let the nurse learn it. The experienced nurse can always tell that a person has taken a narcotic the night before by the patchiness of the colour about the face, when the re-action of depression has set in; that very colour which the inexperienced will point to as a proof of health. There is, again, a faintness, which does not betray itself by the colour at all, or in which the patient becomes brown instead of white. There is a faintness of another kind which, it is true, can always be seen by the paleness. But the nurse seldom distinguishes. She will talk to the patient who is too faint to move, without the least scruple, unless he is pale and unless, luckily for him, the muscles of the throat are affected and he loses his voice. Yet these two faintnesses are perfectly distinguishable, by the mere countenance of the patient. [Sidenote: Peculiarities of patients.] Again, the nurse must distinguish between the idiosyncracies of patients. One likes to suffer out all his suffering alone, to be as little looked after as possible. Another likes to be perpetually made much of and pitied, and to have some one always by him. Both these peculiarities might be observed and indulged much more than they are. For quite as often does it happen that a busy attendance is forced upon the first patient, who wishes for nothing but to be "let alone," as that the second is left to think himself neglected. [Sidenote: Nurse must observe for herself increase of patient's weakness, patient will not tell her.]
