gives the following particulars. During the ten days trial the percentages
absorbed were proteids 82.5, fat 86.9, nitrogen free extract 96, crude
fibre 80, ash 5.7, heat of combustion in calories 86.7. He says,
"generally speaking, the food was quite thoroughly assimilated, the
coefficients of digestibility being about the same as are found in an
ordinary mixed diet. It is interesting to note that 80 per cent. of the
crude fibre appeared to be digested. The results of a number of foreign
experiments on the digestibility of crude fibre by man are from 30 to 91.4
per cent., the former value being from mixed wheat and rye, and the latter
in a diet made of rice, vegetables and meat."
