the string

'Are you anything akin to me, do you think, Jane?'

I could risk no sort of answer by this time: my heart was still.

'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.'
