In the table that follows there are given the values of the 

 fertilizing constituents of the total excreta in each experiment 

 and of the resulting manure from loo pounds of ^ach feed, 

 provided both the solid and liquid excreta are saved. In the 

 calculations the values for the same materials assumed for com- 

 mercial fertilizers in 1904 are used.
