The Whole of it came not at once — Apoplexy

The Whole of it came not at once-1
'Twas Murder by degrees-
A Thrust-and then for Life a chance-
The Bliss to cauterize-

The Cat reprieves the Mouse 5
She eases from her teeth
Just long enough for Hope to tease-
Then mashes it to death-

'Tis Life's award-to die-9
Contenteder if once-
Than dying half-then rallying
For consciouser Eclipse-
(F.485/J.762)
[3] Thrust:: stroke, apoplexy.
[4] cauterize:: to disable the feelings, paralyze, a result of stroke.
[11] rallying:: recovering from the stroke.
[12] Eclipse:: a slow death.

To burning with hot irons, &c. An allusion to cauterizing, sometimes recommended in cases of apoplexy. ─ Hudibras: A Poem (1822)
