STANDING AND LYING 



Standing and lying have been found to exert such an influence on the 

 heat production of cattle that, in order to make comparisons, the observed 

 results must be corrected to a uniform proportion of time standing and 

 lying. The total heat production of each day of the 2-day periods has 

 therefore been corrected to 12 hours' standing and 12 hours' lying in the 

 manner described on page 454 of the paper already referred to (2) and 

 the two days averaged. The distribution of this corrected heat produc- 

 tion has also been computed by the method explained on page 468 of 

 the same publication. The results of these computations are recorded in
