The ratio of the total numbers is again alraost ideritical 

 withthat of Table I, being very nearly three times that of 

 the respective numbers there. The proportion of right- and 

 left-styled flowers shown in the total leads one to believe 

 that the aggregates of these, for any considerable number 

 of plants, will be fairly equal. 



Taking all three tables, the numbers of right- and lefc- 

 stj'led flowers borne hy the several plants are equ.il in six 

 cases out of sixty-two. In thirty-five cases the left-stjled 

 flow^ers, and in twenty-one, the right-styled, are in the 

 majority. 



It would have been well to have had the plants marked, 

 so as to have had fuUer statistics of the respective numbers 

 of right- and left-styled flowers borne by individual plants at 

 different periods. Only one set of observations of this kind 

 was made, and it was found that the right- and left-styled 

 flowers of one plant, counted at three different periods, were 

 as follows : ^ 15 L, 11 R; 16 L, 9 R; 17 L, 4 R. The left- 

 styled preponderated ihroughout, thus suggesting the possibi- 

 lity of individual plants habitually hearing more of one kind 

 than of the other. 



Opportunity was afforded of counting the right- and left- 

 styled flowers of 13 seedlings, which had been raised from 

 purchased seed. The flowers were the first to be produced 

 by ihe plants : —
