Jane Eyre XXV -- chapter 25: A YEAR AND A DAY

1. Paragraph 1 is a fine example of existentialism.
2. The cloven chestnut tree in its description here is like, though perhaps only in portent and not eventual outcome, the white tree of Gondor from The Lord of the Rings (either the original textual version or the cinematic.)  Thoughts?
3. vampyre; vampire  -- application, then?  and is it more or less than the by-now so terribly stereotypical "modern" vampire tropes?  (Fascinating history, of course, but I wouldn't about more than etymologies in this case.)
4. A year and a day.  This law has always boggled me, as much invented, seemingly, for its poetry as its legal application.  But considering its contextual use here in the book, what is Rochester actually saying (you may include exclude other listed English traditions ascribed to this legalese anapest?
5. Interesting: once the tale is confessed and quelled (was it really?), the wind too has died down; but how could she possibly accept the lame, or at least incomplete, explanation from Rochester?
