From Charles Lyell¹   6 October 1860

The geograph^l. vars. of some species on the American & European sides of the Atlantic, Vanessa Atalanta, Pteris aquilina, remarkable. See p. 700, 9^th. Ed. Principles.² The time required by $\frac{9}{10}$ ^th. of the living species to accommodate themselves to the new circums. will never be granted. Not that a red Indian might not be developed into something as good or better than a White Man but as it w^d take 10,000 or more years & he is not allowed as many centuries    he must be improved off the face of y^e earth & he is therefore not transmutable for any practical purpose of salvation in this world.

In no other way can any theory of develop^t. or transmutⁿ. be reconciled with the stationary conditⁿ. of species in general, or the fact that they are dying out instead of becoming altered when their existence is at stake.
