When it comes to quantities of food to be prescribed, the author avoids giving even suggestions. This has been the trouble with the past attempts at reform. Had Luigi Cornaro told us in his autobiography the manner of taking his food with other particulars, instead of giving alone a maximum weight to which he limited himself, he might have saved the world three hundred years of uncertainty and confusion. His twelve ounces of solid food and fourteen ounces of new wine (fresh grape juice) means little. The solid food might have been almost water free or might have contained 50 per cent of moisture. The new wine contained a trifle of sugar and probably more than 95 per cent of water and supplied moisture to the body instead of water. During the Yale tests reported elsewhere, and more fully in the "A. B.-Z. of Our Own Nutrition," the daily ration did not exceed the reported amount of Cornaro, even with the most generous allowance for moisture. I have steadily refused to prescribe by weight or quantity or to suggest the best kinds of foods for any one, but there are so many questions arising from the publicity already given by the Yale experiment, that it will do no harm to give some outline. DIET IN THE YALE EXAMINATION OF THE AUTHOR In the first place the selection of food for this test is no basis of general choice. The analysis of food for its elemental molecule values, and for its heat content, is a very difficult thing to do and takes much time; hence to bring a large variety into a diet during a test would entail enormous labour on the laboratory staff. Knowing this difficulty, when I was requested to choose something which would entirely satisfy my sense of taste gratification so as to best stimulate the flow of the digestive juices, I chose a cereal with a known content value. That is to say, I fed from different brands of cereals, the content value of which was known. A quart of fresh milk a day furnished the moisture required, and was not every day entirely consumed. Maple sugar was the most variable ingredient of the diet in regard to quantity. Of the milk I took nearly or quite one quart each day, of the cereal I averaged about 150 grams, or say 5 ounces, and the demand for the sugar varied from 150 grams to 200 grams, or say 5-7 ounces. This food was taken in at two meals daily,--12-1 and 6-7 P.M.,--and the time required in taking was 12-14 minutes to the meal, including any delay necessitated in taking notes and in weighing the food. These delays were inconsiderable, however, as facilities for weighing and taking notes were perfected and their use well accustomed by the subject. The 26-28 minutes per day, then, may be set down as the careful but industrious eating time required to satisfy the waste and appetite of a man doing 'Varsity Crew work, as reported by Dr. Anderson and Professor Chittenden.
