THE UTILIZATION OF ENERGY. 483 
It need hardly be added that none of these results are directly 
comparable with those computed above, after another method, for 
the wheat gluten as a whole. 
Beet Molasses ——The results of the three experiments upon beet 
molasses show such great differences, as was noted in Chapter X 
and as is further apparent from the following table, that any dis- 
cussion of them would evidently be premature:

Rice.—The two experiments upon swine by Meissl, Strohmer & 
Lorenz, when computed as on p. 454, show that of the (estimated) 
metabolizable energy of the food approximately the following per- 
centages were recovered in the gain:

These results are notably higher than any obtained in experi- 
ments on ruminants. Like the results on barley and cockle below 
they are the expression in another form of the well-known supe- 
riority of the swine as an economical producer of meat. 
Barley.—For the utilization of the energy of this grain the 
single experiment by Meissl, Strohmer & Lorenz gives 70.9 per cent. 
of the (estimated) metabolizable energy. 
Mized Grains.—For mixed grains Kornauth & Arche’s results 
on swine give figures which do not differ materially from-the result 
just computed for barley, viz.:
