spoken of him as absolutely on the side of immutability.

We believe it to be partly accounted for (as Poulton suggests) by the fact
that Mr. Darwin possessed only the third edition (1836 and 1837) and the
fourth edition (1841-51). (14/7. The edition of 1841-51 consists of
reprints of the third edition and three additional volumes of various
dates. Volumes I. and II. are described in the title-page as the fourth
edition; Volumes III. and IV. as the third edition, and Volume V. has no
edition marked in the title.) In neither of these is the evolutionary
point of view so strong as in the second edition.

We have gone through all the passages marked by Mr. Darwin for future
reference in the third and fourth editions, and have been only able to find
the following, which occurs in the third edition (Volume I., 1836, page
242) (14/8. There is also (ed. 1837, Volume II., page 344) a vague
reference to Natural Selection, of which the last sentence is enclosed in
pencil in inverted commas, as though Mr. Darwin had intended to quote it:
"In other parts of Africa the xanthous variety [of man] often appears, but
does not multiply. Individuals thus characterised are like seeds which
perish in an uncongenial soil.")

"The variety in form, prevalent among all organised productions of nature,
is found to subsist between individual beings of whatever species, even
when they are offspring of the same parents. Another circumstance equally
remarkable is the tendency which exists in almost every tribe, whether of
animals or of plants, to transmit to their offspring and to perpetuate in
their race all individual peculiarities which may thus have taken their
rise. These two general facts in the economy of organised beings lay a
foundation for the existence of diversified races, originating from the
same primitive stock and within the limits of identical species."
