In the original, from which the foregoing abstract is copied, Linsser 

 gives the so-called probable error or the limit of uncertainty as 

 deduced from the agreement among themselves of the numerous 

 individual determinations of the physiological constants in zone A, 

 whereas the mean values alone are given in our summary. It 

 appears that the uncertainties are larger for the ripening jDhase than 

 for the leafing and blooming phases, if we consider only their 

 absolute values, but decidedly smaller if we consider their relative 

 values. In general the uncertainty of the constant for leafing is 

 about one-twentieth of its own value, the uncertainty of the constant 

 for blooming is about one-fortieth of its own value, and the uncer- 

 tainty of the constant for ripening is about one-fiftieth of its own 

 value.
