506. ~To this my errand~, etc., _i.e._ in comparison with this errand of
mine and the anxiety it involved. 'To' = in comparison with; an idiom
common in Elizabethan English, _e.g._ "There is no woe _to_ this
correction," _Two Gent._ ii. 4. 138. See Abbott, § 187.
508. ~How chance~. _Chance_ is here a verb followed by a substantive
clause: 'how does it chance that,' etc. This idiom is common in
Shakespeare (Abbott, § 37), where it sometimes has the force of an
adverb (= perchance): compare _Par. Lost_, ii. 492: "If chance the
radiant sun, with farewell sweet," etc.
509. ~sadly~, seriously. Radically, sad = sated or full (A.S. _saed_);
hence the two meanings, 'serious' and 'sorrowful,' the former being
common in Spenser, Bacon, and Shakespeare. Comp. 'some _sad_ person of
known judgment' (Bacon); _Romeo and Jul._ i. 1. 205, "Tell me in
_sadness_, who is that you love"; _Par. Lost_, vi. 541, "settled in his
face I see _Sad_ resolution." See also Swinburne's _Miscellanies_
(1886), page 170.
