348 REPORT OF THE HorTICULTURAL DEPARTMENT OF THE 
nearly related species or varieties overlap each other in the range 
of greatest_frequerney of disiribution and consequently are not 
separable by te mechanical means of solutions; also, because 
the proportion of seeds not of the optimum specific gravity varies 
greatly under diilerent conditions, and hence the average specific 
gravity of differcri samples of the same variety would not be 
constant.
