Letter to William H. Channing
p184“I cannot think about it or write about it except of / "a fair luminous cloud / Enveloping the earth”
Fuller, Margaret. The Letters of Margaret Fuller. Edited by Robert N. Hudspeth. Vol. II. Ithaca: Cornell University Press, 1984.
Inferred Hudspeth identified the first quotation: 'The first quotation is from Coleridge's “Dejection: An Ode”.' The full passage in Coleridge (Stanza IV) reads: 'A light, a glory, a fair luminous cloud / Enveloping the Earth—' Fuller quotes the last two lines of this image.
Title confirmed explicitly by Hudspeth.
