meter of surface, the basal katabolism for 12 hours standing and 12 hours 
lying gives as the maintenance requirement for a 1000-pound steer 5918 ± 560 
Calories. 
The results for the basal katabolism of man reported by Benedict, Emmes, 
Roth and Smith, 5 and by Means 6 present much the same picture as ours upon 
cattle with the exception of a much lower variability.

Correcting for the error shown by D. and E. F. DuBois 7 to be incident to 
the use of the Meeh formula, the means for men and women are as follows:

Including the data obtained by Meissl, Strohmer, and Lorenz 8 by Tangl 9 
and by Fingerling, Kohler and Reinhardt 10 for swine and by Zuntz and Hager

Horse (standing quietly) 948 ± ? 
Considering the nature of the results they show a rather striking degree 
of uniformity and tend to confirm the conclusions of E. Voit 12 that the basal
