Tabus XXII .—Comparison of correlation between (a) the physicochemical constants for the first series of determinations based on Upland Cotton {Meade 
and Acala varieties) and on the F l hybrid and those of the second series of determinations based on Egyptian cotton {Pima variety) of the same duplet 
or triplet; and {b) the constants for the first series of determinations based on Egyptian cotton and those of the second series of determinations based 
on Upland cotton or on the F l hybrid of the same duplet or triplet, in IQ2I
