What do we learn from this investigation ?
With practically 20 grms. of salt daily per man:—
(i) 84.5 per cent. is absorbed and passed out in the urine.
(ii) 2.5 per cent. is unabsorbed and passed out in the fæces.
(iii) 13.0 per cent. is absorbed and eliminated in the sweat.
(iv) average body-weight = 98.8 lbs.
(v) average quantity of urine passed = 1,816 c.c.
(vi) average number of r.b.c. = 4,550,000.
With 14.76 grms. of salt per man daily:—
(i) 88.1 per cent. of the salt is absorbed and passed out in urine.
(ii) 4.2 per cent. is unabsorbed and passed out in the fæces.
(iii) 7.7 per cent. is absorbed and eliminated in the sweat.
(iv) average body-weight=97.9 lbs.
