were in weight as 100 to 45. The two lots were allowed to 

 germinate on sand, and pairs were planted on the opposite sides 

 of four pots. When nearly two-thirds grown they were 

 measured, as shown in the following table : 



Table XLIV. 



Delphinium consolida. 



The six crossed plants here average 14-95, and the six self- 

 fertilised 12-50 inches in height: or as 100 to 84. When fully 

 grown they were again measured, but from want of time only a 

 single plant on each side was measured ; so that I have thought 

 it best to give the earlier measurements. At the later period 

 the three tallest crossed plants still exceeded considerably in 

 height the three tallest self-fertilised, but not in quite so great 

 a degree as before. The pots were left uncovered in the green- 

 house, but whether the flowers were intercrossed by bees or self- 

 fertilised I do not know. The six crossed plants produced 282 

 mature and immature capsules, whilst the six self-fertilised 

 plants produced only 159 ; or as 100 to 56. So that the crossed 

 plants were very much more productive than the self-fertilised.

Twelve flowers were crossed with pollen from another plant, 

 and yielded ten capsules, containing by weight 5 '77 grains of 

 seeds. Eighteen flowers were fertilised with their own pollen 

 and yielded twelve capsules, containing by weight 2 ' 63 grains. 

 Therefore the seeds from an equal number of crossed and self-
