AMERICAN DIGESTION EXPERIMENTS. 
There have already been made in America about forty digestion 
experiments, but as the results are maccessible to nearly all, I 
have brought together in Table B all those which have come 
under my observation. This is a good beginning, and it is gratify- 
ing to see the manifest desire on the part of feeders for more 
information on this subject. In the future it is hoped more atten- 
tion will be given by investigators, to determining the digestibility 
of rations such as are being fed in practice by our most progressive 
feeders. 
As is well known, not all of the food eaten by an animal is 
digested, and the figures, called coefficients of digestibility, given 
in Table B, mean that the per cent indicated may be expected to 
be digested. For the benefit of feeders I have made the calcula- 
tions and given the results in Table C and following tables, so 
that Table B is more for reference in future work.
