But in addition to this, 4046 grins, of non-proteid matter were 
used up. Now this, as already indicated, we may practically regard 
as fat, since the cabohydrates need not be considered. Now fat 
contains 30 per cent, of water, and hence this amount would repre- 
sent 2832 grms. of solid fat, and in this would be contained about 
2174 grms. of carbon. 
Thus we see that in all 2230 grms. of carbon were lost from the 
body in twenty-eight days; that is, during the fast there was an 
average daily excretion of 77 '6 grms. of carbon. Now in a man on 
ordinary diet and work about 280 grms. of carbon are daily 
excreted, so that the carbon excretion fell to about J of its normal 
amount. 
On the other hand, 147 grms. nitrogen being excreted in these 
twenty-eight days, we have a daily excretion of 5*2 grms. instead of 
the normal 15 or 16 grms., so that the nitrogenous excretion also 
fell to about J of its normal amount. 
In this case, then, apparently the proportion of the proteid to the 
non-proteid waste was undisturbed during starvation. 
Is it possible, from these observations, to come to any general 
conclusions in regard to the probable composition of the body at the 
end of the fasting period as compared with the beginning 1 Taking 
as our basis the composition of the body of a man aged 33 years, as 
given by Bischoff (Zitsch. f. rat. Med ., 3d Beihe, Bd. xx. p. 75), we 
may conclude that at the beginning of the fast Jacques’ body had 
something of the following composition : — 
Total weight on 26th October, . . 60,675 grms. 
“ Flesh,” i.e., muscle, liver, lung, &c., . 35,550 „ 
Pat, 10,834 „ 
His condition at the end of the experiment may be calculated by 
subtracting from these figures the loss in total weight, in flesh, and 
in other substances, or fat : —
