Journal 1840
p56“W.E on art / p 7 - If you see a drawing - once, give it your blessing you will never see it again.”
Fuller, Margaret. "Journal 1840." Houghton Library, Harvard University; bMS Am 1086 (85); Box 5 (85).
Inferred Fuller cites 'W.E on art / p 7' and 'p 8' and quotes observations about looking at drawings and seeing the moon — this matches Emerson's essay 'Thoughts on Art,' published in The Dial, January 1841, though written in late 1840. Fuller as Dial editor would have seen it in manuscript. W.E.' is Waldo Emerson (Ralph Waldo Emerson).
