{[i Hoary x Glabroi le 58 plants recorded as glabrous been allowed to mature 

 3 is little doubt that the expectation f quarter-hoary 

 tilabrous would have been recorded. (See similar case 

 speriment 20.) The i-'o plant from which F3 was derived 

 recorded as being distinctly intermediate between the 

 ary and the glabrous condition, i.e. quarter-hoary, and 

 e would certainly give rise to some quarter-hoary 

 ring. We may regard the total 58 as representing 

 •ous and ^ hoary summed together, the ratio of the 

 hoary to the sum of tliese two being almost exact. 

 [^ Hoary ^ Glabrou case a few plants were grown to the flowering stage, but 

 aajority were discarded as seedlings, with the result that 

 ibly i// as well as ^H were recorded as glabrous. The 

 jrtion of fully hoary to the other three grades taken 

 her is not far out. 



[| Hoary x Glabroujear in mind (1) that liere as in the preceding experiments

the fully hoary form is likely to have been classed with 

 type, we may take these results, so far as they go, as 

 ! as near expectation as could be expected under the 

 mstances. For whereas we have reeoi'deil a total of 

 H, 107 hH, 98GG the result of classifying the JJK form 

 H and the ill with G should give iryMH, 210 }^H, SSOG. 

 excess of G is no doubt made up of the missing Ul
