expressions seem to have given you. The objections are not made by
Tyndall or Huxley; but they are objections made by me, which I stated to
them, and in which they agreed--Tyndall expressing the opinion that I
ought to make them public. I name this because you may otherwise some
day startle Tyndall or Huxley by speaking to them of _their_ objections,
and giving me as the authority for so affiliating them.--Very truly
yours,

HERBERT SPENCER.

SIR C. LYELL TO A.R. WALLACE


_73 Harley Street, London, W. November, 1867._

Dear Wallace,--You probably remember an article by Agassiz in an
American periodical, the _Christian Observer_, on the diversity of human
races, etc., to prove that each distinct race was originally created for
each zoological and botanical province. But while he makes out a good
case for the circumscription of the principal races to distinct
provinces, he evades in a singular manner the community of the Red
Indian race to North and South America. He takes pains to show that the
same American race pervades North and South America, or at least all
America south of the Arctic region. This was Dr. Morton's opinion, and
is, I suppose, not to be gainsaid. In other words, while the Papuan,
Indo-Malayan, Negro and other races are strictly limited each of them to
a particular region of mammalia, the Red Indian type is common to
Sclater's Neo-arctic and Neo-tropical regions. Have you ever considered
