Summary

Good news: one little rabbit has a white forefoot.

Summary

Is much obliged for information [about rabbits?].

Summary

The mark he had thought a variation is not, and he thinks his infusion still too small even when the blood is defibrinised.

Summary

Better news about the rabbits.

Summary

Variety in rabbits less than he hoped for; will try a new mode of transfusion.

Summary

Thanks CD for his help and encouragement in his series of experiments [to test Pangenesis].

Summary

Experiments are not going well, but the quantity of blood transfused was small.

Summary

Two, perhaps all three, doe [rabbits] are sterile after the transfusions; will try another method.

Summary

[William Rathbone] Greg is author [of "Failure of ""natural selection"" in the case of man", Fraser’s Magazine 78 (1868): 353–62].

Comments on findings in J. M. Duncan [Fecundity, fertility, sterility and allied topics (1866)].

Saw A. D. Bartlett about monkeys.

Summary

Thanks for a woodcut sent by ARW for Descent.

Congratulations on his removal from London,

and praise of his review of Francis Galton ["Hereditary genius", Nature 1 (1870): 501–3]. CD agrees with every word of it.

Summary

Definite results have been delayed, but he is optimistic.

Summary

Pangenesis supports the existence of gemmules; does not accept Galton’s experiments as disproving their existence or importance.

Summary

Comments on FG’s article ["Hereditary improvement", Fraser’s Mag. 87 (1873): 116–30]. Finds it "the sole feasible, yet I fear utopian, plan of procedure in improving the human race".

Thanks for rabbits for Balfour.

Mentions reading W. R. Greg’s Enigmas [of life (1872)].

Summary

Again seeks help with his rabbits; hopes one of CD’s men can take them.

Summary

Responds to suggestions and criticisms CD made to "theory of heredity" [see 10245].
