On approaching a sick person, our first question, whether put into words or not, is naturally, Is there much the matter?
Other inquiries follow, such as these: Has he fever ? Is he very weak ? Is his head clear ? Does he suffer pain anywhere ? What organ or function of his body is not as it ought to be ?
So we proceed from one thing to another in forming what doctors call a diagnosis of a case. Experience makes such an examination more and more easy, rapid and efficient. A besetting temptation, even with physicians, is, when enough has been found out to give a probable name for the malady of the patient, to conclude at once that this is the whole matter, and that we know all about his case. This cannot be true, however, unless we have carefully scrutinized all his organs, or at least have satisfied ourselves on good evidence as to the presence or absence of disorder in them all.
Our plan here makes suitable only a short account of the principal symptoms found in connection with different parts of the body, and their meaning; or, at least, the conditions with which they are most likely to be associated.
