p. 22, par. 3, line 2, for " falls" read " fall." 



p. 63, line 12, for "AabbC" read " AaBbc." 



p. 66, in heading, for " OF HYBRIDS " read " OF THE HYBRIDS.' 



Note to p. 125. None of the yellow seeds produced by Laxton's 

 Alpha germinated, though almost all the green seeds sown gave 

 healthy plants. The same was found in the case of Express, another 

 variety which bore some yellow seeds. In the case of Blue Peter, on 

 the contrary, the yellow seeds have grown as well as the green ones. 

 Few however were wholly yellow. Of nine yellow seeds produced by 

 crossing green varieties together (p. 131), six did not germinate, 

 and three which did gave weak and very backward plants. Taken 

 together, this evidence makes it scarcely doubtful that the yellow colour 

 in these cases was pathological, and almost certainly due to exposure 

 after ripening.
