That it is as nutritious for old as well as young we have an interesting proof in the fact that the first Englishman born in Jamaica, Colonel Montague James, who lived to the age of 104, took scarcely any food but cocoa and chocolate for the last thirty years of his life. For athletes and all who desire the development of the muscular tissues, its use is most beneficial. Professor Cavill, in his celebrated swim from Southampton to Portsmouth, and his nearly successful attempt to swim across the English Channel, considered it to be the most concentrated and sustaining food he could use for that trying test of endurance. In his "Treatise on Food and Dietetics," Dr. Pavy remarks that: "Containing, as pure cocoa does, twice as much nitrogenous matter, and twenty-five times as much fatty matter as wheaten flour, with a notable quantity of starch, and an agreeable aroma to tempt the palate, it cannot be otherwise than a valuable alimentary material. It has been compared in this respect to milk. It conveniently furnishes a large amount of agreeable nourishment in a small bulk, and, taken with bread, will suffice, in the absence of any other food, to furnish a good repast." Indeed, the value of cocoa as food for ordinary mortals as well as for mythical beings cannot be better summed up than in the words of Professor Lankester, Superintendent of the Food Collections at South Kensington, who declares: "It can hardly be regarded as a substitute for tea and coffee; it is, in fact, a substitute for all other kinds of food, and when taken with some form of bread, little or nothing else need be added at a meal. The same may be said of chocolate." FOOTNOTES: [1] According to Drs. Playfair and Lankester: Tea contains 3 per cent. theine. Coffee " 1 3/4 " caffeine. Cocoa " 2 " theobromine. Probably the proportion of caffeine in coffee would be more correctly stated as 1 1/4 per cent. Theine and caffeine are identical, but theobromine (C_{7}H_{8}N_{4}O_{2}) differs from both in the greater proportion of nitrogen which it contains.
