ounce) of protein, 0.07 gram of calcium, 0.08 gram of phosphorus, and 1.8 milli- 
grams of iron. It would furnish, therefore, 96 per cent of the energy a man 
needs daily, 5 per cent of the protein, 10 per cent of the calcium, 6 per cent of 
the phosphorus, and 6 per cent of the iron. This is shown in the following

(About 2 cups.) 
One pound of double cream supplies about 1,700 calories of energy, 9 grams 
(about \ ounce) of protein, 0.33 gram of calcium, 0.26 gram of phosphorus, and 
0.5 milligram of iron. It would furnish, therefore, 49 per cent of the energy 
a man needs daily, 9 per cent of the protein, 49 per cent of the calcium, 20 per 
cent of the phosphorus, and 3 per cent of the iron. This is shown in the fol-
