In the Biographical Notice of the Author, by Henry Austen, he wrote:

Her reading was very extensive in history and belles lettres; and her memory extremely tenacious. Her favourite moral writers were Johnson in prose, and Cowper in verse. It is difficult to say at what age she was not intimately acquainted with the merits and defects of the best essays and novels in the English language. Richardson's power of creating, and preserving the consistency of his characters, as particularly exemplified in 'Sir Charles Grandison', gratified the natural discrimination of her mind, whilst her tast secured her from the errors of his prolix style and tedious narrative. She did not rank any work of Fielding quite so high. Without the slightest affectation she recoiled from every thing gross. Neither nature, wit, nor humour, could make her amends for so very low a scale of morals.
