Description
Darwin asks his son, Francis, and his Cambridge University friends to check his Latin. Latin was not Darwin's strong point and he frequently relied on his sons and colleagues to check his efforts (see letter to George Robert Gray, below).
The enclosure to this letter has not been found but it is likely that the passage in question involved a discussion of the genitalia of ‘Hottentot’ (a term used in the nineteenth century to refer to peoples of the south-western Africa) women which featured in Descent Vol. 2, p. 345 (see letter from Andrew Smith and the associated extract from Descent, in this case).
