- f1 5941.f1The year is established by the reference to the second printing of Variation (see n. 4, below).
- f2 5941.f2Newton's letter to CD has not been found.
- f3 5941.f3In Variation 1: 237, CD mentioned the Chinese goose (or swan goose), Anser cygnoides, as the only domesticated bird whose wild parent form was said to be still unknown, or extinct. In the second edition of Variation this passage was removed.

XV.
- f4 5941.f4A second printing of Variation was ordered after all copies of the first edition had been sold (see letter from John Murray, 6 February ).
