The other contents of these four volumes are: a series of lessons in spelling and reading, which, because prepared especially for her child, Fanny Imlay, are an interesting relic; the "Letter on the French Nation," mentioned in a previous chapter; a fragment and list of proposed "Letters on the Management of Infants"; several letters to Mr. Johnson, the most important of which have already been referred to; the "Cave of Fancy," an Oriental tale, as Godwin calls it,—the story of an old philosopher who lives in a desolate sea-coast district and there seeks to educate a child, saved from a shipwreck, by means of the spirits under his command (the few chapters Godwin thought proper to print were written in 1787, and then put aside, never to be finished); an "Essay on Poetry, and Our Relish for the Beauties of Nature," a short discussion of the difference between the poetry of the ancients, who recorded their own impressions from nature, and that of the moderns, who are too apt to express sentiments borrowed from books; and finally, to conclude the list of contents, the book contains some "Hints" which were to have been incorporated in the second part of the Rights of Women which Mary intended to write. These fragments and works are intrinsically of small value.
