Asks CD’s advice on procuring rabbits for experiments [to test Pangenesis by transfusing alien blood into does and breeding from them].
Praises FG’s book [Hereditary genius (1869)]. CD is converted by its argument. Previously CD believed men did not differ much in intellect, but only in zeal and hard work.
Greatly pleased by approbation from CD, whom he admires and whose Origin did much for him.
Interim report on the experiments with rabbits [to test Pangenesis].
Experiments are not going well, but the quantity of blood transfused was small.
Variety in rabbits less than he hoped for; will try a new mode of transfusion.
Better news about the rabbits.
The mark he had thought a variation is not, and he thinks his infusion still too small even when the blood is defibrinised.
Rabbits still running true; hopes to increase alien blood to 30%.
Is much obliged for information [about rabbits?].
Good news: one little rabbit has a white forefoot.
Thanks CD for his help and encouragement in his series of experiments [to test Pangenesis].
Two, perhaps all three, doe [rabbits] are sterile after the transfusions; will try another method.
[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.
Definite results have been delayed, but he is optimistic.
CD will take care of the eight little rabbits. FG outlines their future.
Arrangements for transfer of rabbits to CD.
Reports safe arrival of rabbits.
Upset to learn he has misrepresented CD’s doctrine on Pangenesis [in Proc. R. Soc. Lond. 19 (1871): 393–410]. Hopes that CD’s letter to Nature [3 (1871): 502–3; Collected papers 2: 165–7] will clarify the doctrine and attract attention to it.
Is sending his reply to Nature, justifying his misunderstanding as well as he can [see 7717].
