This is a handsome and convenient chart for ascertaining at a glance the proportion of carbohydrates, proteins, fat, water and mineral matter in the various foodstuffs. The amounts are indicated by colored lines. The fuel value in calories per pound is given at the end of the line. The chart can be hung on the wall or folded to folio size. The device bids fair to be useful as a reminder of the detailed composition of food which it is imposible to bear constantly in mind and which often is found in books only after considerable trouble.
