[_Bug_ in Welsh means a ghost or goblin. It is probably the
same with the Icelandic _Paki_, an evil spirit. But on this
etymology our correspondent can consult an article by Sir F.
Palgrave, on the "Popular Mythology of the Middle Ages." in the
_Quarterly Review_, vol. xxii.; a paper, by Mr. Thoms, on the
"Folk Lore of Shakspeare," No. 6.; "Puck's several Names," in _The
Athenæum_, Oct. 9. 1847; and lastly, Mr. Keightley's most
interesting work, _The Fairy Mythology_. vol. ii. p. 118., of
which we are happy to hear that a new and enlarged edition may
shortly be expected.]
