Diet I.

Total intake of nitrogen   =374.95 grms. Total output—            
          N. in urine         191.48 grms.
          .5 grm. N. daily       12.50
      Total N. metabolism       203.98
              =54.40 per cent. of N. of diet
              =8.15 grms. of N. per man daily.

Diet II.

Total intake of nitrogen   =410.10 grms. Total output—            
          N. of urine         225.66 grms.
          .5 grm. daily         12.50
      Total N. metabolism       248.16
              =60.51 per cent. of N. of diet
              = 9.92 grms. of N. per man daily.

       From these investigations we see that—

                          from Diet I 203.98 grms. of nitrogen undergo metabolism,
                          from Diet II 248.16 grms. of nitrogen undergo metabolism
                          now Diet II is made up of Diet I + 16 ozs. of mutton + 10 ozs. of Burma rice,

and we know from previous work that a diminution of 10 ozs. of Burma rice in a
diet of the above type makes very little difference in the amount of nitrogen
absorbed, particularly when the diminution of nitrogen in rice is counterbalanced
by a more easily absorbed nitrogen in the form of meat. We may, therefore, take
it that the increased output is largely due to the presence of mutton in the diet.
Therefore 248.16 grms.—203.98 grms.=44.18 grms. is practically derived from
52.15 grms. N. of mutton=about 84.71 per cent. of the N. of mutton absorbed.
