ERRATA.

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.
