And if we take an active man of 140 lbs., and apply these rules, we find that he will require 1,400 grains of albumen per day, which will produce about 466 grains of urea per day when completely digested and metabolised. With regard to urea, I may say that the percentages of albumen values, to be given in the diet tables that follow, have been found by me from practical trial to be very close to the truth; for though on a weighed diet, continued from day to day, urea will be one day below and another above the quantity calculated from the albumen values of those foods, when taken over days or weeks, these fluctuations tend to balance each other, and over such a period the urea calculated from the albumens generally comes very close indeed to the urea found. These fluctuations no doubt arise from variations in the time of digestion of the foods used, as the digestion and absorption of a food taken one day is not necessarily concluded in time for the twentyfour hours' division of the urine; and then, again, when albumens have been absorbed, they may, as we have seen reason to believe, remain either in the blood or the tissues as a reserve of force till a special call for force production and activity is made (see fig. 1 and remarks upon it; also ' Uric Acid," p. 335). But when allowance is made for these causes of variation, the values to be given are, I believe, quite sufficiently accurate for our practical purposes. Now the albumens required for this man of 140 lbs. can be got from: --Table I. 340 grs. 104 525, 210 68 153 1,400 Now it is obvious that such a diet list may be varied greatly in very many directions, and that such variations may be used as temporary changes...
