Note 349 — SCENE II.
Reading edition
This is a term of the chase. Gascoigne, in his book of hunting, 1575, p. 242, enumerates it among "other generall termes of the hart and his properties. When he (the hart) is foamy at the mouth, we saye that he is embost." So in "The Shoemakers' Holiday; or, The Gentle Craft," 1610, sig. C 3—
"Besides, the miller's boy told me even now, He saw him take soile, and he hallowed him, Affirming him so embost, That long he could not hold."
