The coefficient of correlation, calculated from the above nunibers, between 
parents (selfed) and offspring (selfed) is "378. This is low for mid-parental corre- 
lation ; but as all the generations arose by self-fertilisation we ought to have 
practically no correlation at all according to the pure-line hypothesis, for the two 
original parents (Cj and Bi) were closely similar to each other in the character 
under investigation. 
6. Purple Spotting of the Corolla. 
The purple spotting of the lower surface of the corolla-tube and lower lip 
varied greatly in the original parent plants, and the character was obviously 
inherited. The amount of spotting had little relationship to the intensity of the 
general coloration of the corolla, and " white " flowers were sometimes richly 
spotted with purple. 
The percentage area of the lower surface covered with spots was estimated by 
comparing the flowers with a seiies of diagrams each covered with a definitely 
known percentage of spotting. With practice it was found that sufficiently 
uniform results could be obtained by this method.
