Note 93 — ACTUS V.[92]
Reading edition
Perhaps we should read quarell'd poison; i.e., such poison as arrows are imbued with. Quarels are square arrows. So in the "Romaunt of the Rose," v. 1823—
"Ground quarelis sharpe of steele."
—Steevens.
[The two words are the same, quarled being a contracted form of quarell'd.]
