only produced a pod, and it contained four Peas, which did 

 not differ in appearance from the others of the female parent. 

 It thus appears from the different results in this stage of the 

 experiments made by Mr. Goss and Mr. Seton, that the ap- 

 pearance of the fruit in the first instance is sometimes affected 

 by extraneous impregnation, and sometimes not ; the impreg- 

 nation being effectual, as it was proved to have been, by the 

 progeny in both of these instances, and it seems desirable that 

 this interesting point, on which so much difference of opinion 

 has arisen,* partly from observation, and partly from analogi- 

 cal reasoning, should be subjected to further experiment. 



The plants which grew from the four Peas obtained by 

 Mr. Seton, seemed to partake of the nature of both parents, 

 being taller and more diffuse than the Dwarf Imperial, and 

 less so than the male white parent ; but the pods resembled 

 those of the former, being short, and having but few Peas in 

 each. On their ripening it was found that instead of their 

 containing Peas like those of either parent, or of an appearance 

 between the two, almost every one of them had some Peas of 

 the full green colour of the Dwarf Imperial, and others of the 

 whitish colour of that with which it had been impregnated 

 mixed indiscriminately and in undefined numbers ; they were 

 all completely either of one colour or the other, none of them 

 having an intermediate tint, as Mr. Seton had expected. 

 The representation of one of the pods in Plate IX. Fig. 1. 

 conveys a very perfect idea of its appearance.
