* These results are additional to those previously recorded. The recognition of, and 

 classification into, a larger number of categories made the inclusion of the earlier records 

 in the present analysis impracticable, though the size of these families was in any case too 

 small to have any real value (loc. cit. p. 153, Experiments 7—11). 



t In the earlier account (loc. cit. p. 153, Experiment 7) an F^ individual from a mating 

 of this kind was recorded as quarter-hoary. In reality no doubt the plant will have 

 belonged to the mid-hoary class, a grade which at the time had not yet been recognised. 

 This remark applies equally to the record of quarter-hoary plants in Experiment 8 of the 

 earlier account.
