B. het seedlings from Hom. plant [no IV short-styled by own pollen) but crossed heteromorphically; for I got 1 long- & short-styled plant from the first union.— These seedlings are grandchildren of first hom union of short-styled.

Summary

Black worsted white wool

[data not transcribed]

Speak of "Short-styled" "Long-styled " sho family.

This is strong vase their grandchildren were offspring of a heteromorphic union between 2 homomorphic plants from short-styled; & yet when their grandchildren were crossed heteromorphically with the hom grandchildren from long-styled, product of seed not increased: sterility is indelible in them.

Trial Results of B.

(50 pods on 15 Plants were produced without any aid; but these did not include single seed.)

These 15 plants were all short-styled, (though result offspring of a Heteromorphic union between 2 Hom. plants)

12 flowers were fertilised by own pollen (Black wool) they produced 8 pods with seed, on average containing 21.8 seed per capsule; but omitting 2 capsules with only 9 & 5 seed, the fairest average is 26.4 per pod. = so that these are, perhaps by chance, less fertile than A!!

Six flowers were fertilised heteromorphically with pollen not related by descent of the long-styled Hom. grandchildren seedlings called C: these 6 produced only 3 pods with seed, on average 23.6; but omitting one with 6; average is 32.5; but this evidently too high. In both cases one pod in each contained 35; I may say of equal fertility. This is the same degree of fertility as A had however crossed. — /over

The comparison is very far from correct, but above results will perhaps be more intelligible, if we suppose that ordinary marriages produced on average 6 children but that when cousins married the product was only 3 children. Now the strange fact is that these children from cousins however if married with any other cousins, the most healthy & productive though not the most distant relatives whatever (This is strictly correct for long-styled & short-styled families are not relatives) yet should never produce more than 3 children; the fertility of offspring from cousins from being thus permanently reduced.—
