[Cross and self fertilisation, p. 31: "Crossed and self-fertilised Plants of the Second Generation.—Flowers on the crossed plants of the last generation (Table I.) were crossed by pollen from distinct plants of the same generation; and flowers on the self-fertilised plants were fertilised by pollen from the same flower. The seeds thus produced were treated in every respect as before, and we have in Table II. the result."]
