hocus-pocus

[T]hat which we call Good Humour, is in Truth but a ſort of Slight of Hand in Diſcourſe, or a Faculty of making Truths look like Appearances, or Appearances like Truths. Now this Gift of Hocus Pocuſing, and of Diſguiſing Matters, is ſo Surpriſing and Agreeable on the one hand, that it muſt of Neceſſity be a very ſtrong Temptation to the Quitting of the Beaten Road on the other.

May be regarded as a noun use.]
