Had the whole day to myself; as I did not attend the afternoon recitation. Spent my Time in reading Ferguson, and Saunderson.1
1. Nicholas Saunderson, The Elements of Algebra, In Ten Books..., 2 vols., Cambridge, England, 1740 (Harvard, Catalogus Bibliothecae, 1790 description begins [Isaac Smith, comp.], Catalogus Bibliothecae Harvardianae Cantabrigiae Nov- Anglorum, Boston, 1790. description ends , p. 1). JQA may have used his personal copy of Saunderson, recorded among his books in 1784, which is no longer in his or the other Adams’ libraries ([Christian Lotter], Inventory of JQA’s books, 6 Nov. 1784, Adams Papers).
