A thin thread

“Because,” he said, “I sometimes have a queer feeling with regard to you—especially when you are near me, as now: it is as if I had a string somewhere under my left ribs, tightly and inextricably knotted to a similar string situated in the corresponding quarter of your little frame.  And if that boisterous Channel, and two hundred miles or so of land come broad between us, I am afraid that cord of communion will be snapt; and then I’ve a nervous notion I should take to bleeding inwardly.  As for you,—you’d forget me.”--Jane Eyre, chapter 23

Spotted whilst watching the wonderful new film of the book on American flight 596 from Buenos Aires to JFK, confirmed via e-text. Compare to:

And they went further and further from her, being attached to her by a thin thread (since they had lunched with her) which would stretch and stretch, get thinner and thinner as they walked across London; as if one's friends were attached to one's body, after lunching with them, by a thin thread, which (as she dozed there) became hazy with the sound of bells, striking the hour or ringing to service, as a single spider's thread is blotted with rain-drops, and, burdened, sags down. So she slept.--Mrs. Dalloway.

You never know when you'll find a footnote.
