To:
Nature
Date:
[before 27 Apr 1871]
Source of text:
Nature , 27 April 1871, pp. 502–3
Summary:

Replies to Francis Galton’s paper on tranfusing blood between rabbits to test Pangenesis [Proc. R. Soc. Lond. 19 (1871): 393–40]. FG’s conclusion that his experiments prove Pangenesis to be false is "a little hasty", since CD had never maintained that gemmules in the blood formed any part of his hypothesis.
