(See Nitchie, _Mary Shelley_, p.

178.) [9] The account of Diana in _Mathilda_ is much better ordered and more coherent than that in _F of F--B_.
[10] The description of the effect of Diana's death on her husband is largely new in _Mathilda_.

_F of F--B_ is frankly incomplete; _F of F--A_ contains some of this material; _Mathilda_ puts it in order and fills in the gaps.
[11] This paragraph is an elaboration of the description of her aunt's coldness as found in _F of F--B_.

There is only one sentence in _F of F--A_.
[12] The description of Mathilda's love of nature and of animals is elaborated from both rough drafts.

The effect, like that of the preceding addition (see note 11), is to emphasize Mathilda's loneliness.
