The experiments on which the quoted data were based were 
made, one by Utah Experiment Station, using two steers; one by 
the New York Experiment Station, using a cow; one by the Colo¬ 
rado Station, using two steers. Additional experiments which 
have appeared since the compilation of Jordan and Hall was made 
are, so far as I have been able to find, the following:

than 
the averages of 
other 
experimenters, but are within the bounds of probability, with the 
exception of the fat or ether extract, which in my series is nega¬ 
tive, and we assume, tentatively only, that the results are erro-
