Adams is copying here from Joseph Addison's eleven-part essay entitled βOn the Pleasures of the Imagination,β which appeared in the
Spectator papers between 21 June and 3 July 1712, Nos. 411β421. The penciled notation in brackets is an editorial insertion identifying the beginning of the tenth part of Addison's essay. Adams concluded his copying of this essay on 13 April 1756. He wrote here in his small hand, entirely filling the page to conserve paper. For a calendar of his entries in his Commonplace Book, see p.
7β10, below.
