It was written from Forncett, on the 26th of June, 1791.

She is speaking of her two brothers, William and Christopher.

Of Christopher she says: "His abilities, though not so great, perhaps, as his brother's, may be of more use to him, as he has not fixed his mind upon any particular species of reading or conceived an aversion to any.

He is not fond of mathematics, but has resolution sufficient to study them; because it will be impossible for him to obtain a fellowship without them.
William lost the chance, indeed the certainty, of a fellowship, by not combating his inclinations.

He gave way to his natural dislike to studies so dry as many parts of the mathematics, consequently could not succeed in Cambridge.
