Mimulus luteus (First Generation). Ten flowers on the crossed 

 plants were fully expanded before one on the self-fertilised.

 generations a crossed plant flowered before one of the self- 

 fertilised in all three pots. 



Mimulus luteus (Fifth Generation). In all three pots a crossed 

 plant flowered first; yet the self-fertilised plants, which 

 belonged to the new tall variety, were in height to the 

 crossed as 126 to 100. 



Mimulus luteus. Plants derived from a cross with a fresh stock, 

 as well as the intercrossed plants of the old stock, flowered 

 before the self-fertilised plants in nine out of the ten pots. 



Salvia coccinea. A crossed plant flowered before any one of the 

 self-fertilised in all three pots. 



Origanum vulgare. During two successive seasons several 

 crossed plants flowered before the self-fertilised. 



Brassica oleracea (First Generation). All the crossed plants 

 growing in pots and in the open ground flowered first. 



Brassica oleracea (Second Generation). A crossed plant in 

 three out of the four pots flowered before any one of the 

 self-fertilised. 



Iberis umbellata. In both pots a crossed plant flowered first. 



Eschscholtzia californica. Plants derived from the Brazilian 

 stock crossed by the English stock flowered in five out of 

 the nine pots first; in four of them a self-fertilised plant 

 flowered first ; and not in one pot did an intercrossed plant 

 of the old stock flower first. 



Viola tricolor. A crossed plant in five out of the six pots 

 flowered before any one of the self-fertilised. 



Dianthus caryophyllus (First Generation). In two large beds 

 of plants, four of the crossed plants flowered before any one 

 of the self-fertilised. 



Dianthus caryophyllus (Second Generation). In both pots a 

 crossed plant flowered first. 



Dianthus caryophyllus (Third Generation). In three out of 

 the four pots a crossed plant flowered first ; yet the crossed 

 were to the self-fertilised in height only as 100 to 99, but in 

 weight as 100 to 49. 



Dianthus caryophyllus. Plants derived from a cross with a fresh 

 stock, and the intercrossed plants of the old stock, both
