* The total amount of rhamnose (24.3 grms.). was given on the first day, 
but it is estimated from the results for the carbon excretion that this amount 
of it was not metabolized until the second day. 
The results as to net availability obtained by comparison with 
the several fasting days vary considerably, as.the following state-
