seeker after health often to try the same substance under a dozen different appellations. These remarks are not made for the purpose of decrying in any way the merits which these preparations may have but only to illustrate a very marked tendency on the part of many people to attribute extreme virtues to ordinary food substances which are sold under attractive and sometimes deceptive names and whose properties and virtues are advertised in an expert manner. Because a food substance consists almost wholly of pure protein is no indication whatever of its exceptionally high food value. Protein is only one form of food and a concentrated ration of protein in any of these forms is just as likely to do harm as good. For emergency rations, for economy in transportation, and for certain diseased conditions of the digestive organs these preparations are undoubtedly valuable, but they have little claim upon the general public in a state of health as staple articles of diet. They are much more nutritive than the extracts of beef and other meats which have obtained a vogue wholly out of proportion to their dietetic or medicinal value.
