This case illustrates the fact that each case should be treated scientifically, intelligently, and on its merits. It is as futile as it is dangerous for the unlearned to prescribe dietetic rules for the ailing, the weak, and the obese. " She wants support," a sympathetic friend will say of a poor invalid suffering from the nausea and weakness of advanced Bright's disease, and will proceed to recommend steak and port wine, ignorant of the fact that she is thereby increasing the effete products in the blood of the patient, which are the causes of the symptoms remarked. Or another will tell of a great reduction in size brought about in himself by a meat diet and mountaineering, and will unhesitatingly prescribe the same for a fat friend whose pallor and lethargy bespeak a fatty heart and perhaps damaged kidneys. Dietetic treatment is but reasonable medical treatment based on principles or knowledge more scientific and accurate as a rule than therapeutic treatment, and it should be undertaken or prescribed only after a careful study of the causes of the condition complained of.
