taken from the same author:

“As wicked dew as e’er my mother brushed

“With raven’s feather from unwholesome fen,

“Light on you both!” [Tempest.]

“Ye fen-suck’d fogs, drawn by the powerful sun,

“To fall and blast &c.” [King Lear.]

Thus again in Ella:

“O thou, whate’er thy name, or Zabalus or Queede,

“Come steel my sable spright, for fremde and doleful deed—”
