THE FUTURE OF MEDICINE.^ 

 The future occupations and interests of 

 the medical profession are to be in some 

 respects different from those of the past, 

 and they are to be more various. The 

 ordinary physician has for the last hundred 

 years been ahnost exclusively a man de- 

 voted to the treatment of diseases already 

 developed in human bodies or of injuries 

 already incurred. He made his diagnosis, 

 and then sought remedies and a cure. He 

 was the sympathetic and skilful helper of 

 sick or injured persons. Most of the cases 

 that came under his care were cases consid- 

 ered plain as to symptoms, period and ac- 

 cepted treatment. The minority of cases 

 were obscure, and called for unusual knowl- 

 edge and skill in discerning the seat of the 

 disorder, or the approximate cause of the 

 bodily disturbance. Hence the special 

 value of the experienced consultant, who 

 was ordinarily a m.an of some peculiar nat- 

 ural gift of body, mind or temperament, 

 possessing also in high degree the faculty 

 of keen observation, and the habit of elim- 

 inating irrelevant considerations, and ulti- 

 mately finding his way to the accurate, 

 limited inference from the facts before him. 

 Both the ordinary physician and the con- 

 sultant have already been much helped by 

 the extraordinary progress made in medical 

 science during the last thirty years; but 

 they have been helped chiefly to a surer 

 recognition of diseases established in human
