generally grown in pots in competition with each one another, and always under as closely similar conditions as could possibly be attained. so as not to compete. In several cases the mean heights of plants of the same species intercrossed and self-fertilized during several With several of the species, the crossed seedlings were again crossed, & the self-fertilised seedlings again self-fertilised, & thus successive generations are given; and in those cases the self were raised & measured as may be seen in Table A. fertilised plants of the self-fertilised plants were again self-fertilised, and the crossed parent of the crossed plants were again crossed these latter lants shows became Owing to this manner of proceeding, the crossed plants in this Table became in the later generations more or less closely inter related.

(In Table B the relative weights of the same crossed and self-fertilized plants after they had flowered and were cut down, as in table A are grown in the few cases in which they was were ascertained.

The results deduced from the weight are, I think, more striking and trustworthy than those deduced from their relative heights.)

(The most important Table is that of C, as it includes the relative heights, weights, and fertility of plants raised from parents crossed by a fresh stock (that is by non-related plants grown in a under different place conditions, or by crossed a distinct sub-variety, in comparison with self fertilised plants
