                                   —Thomas Arnold, 1795–1842

     The lucubrator's† day  is  litrefacient,‡  to  be  sure
(e.g. four post- to eight ante-meridiem); but the georgical§
is superior (media nox to four post meridiem).**

     While  facient  men†† prefer either to the journal‡‡ or
illucubrate day, one is tardy and sinister; the other, fresh
and dextrous.

  Formed  on analogy with obdurefacio [< obdurare]
as opposed to, say, afficio [< affeci]; on account
of the strong a and first conjugation.
  The elision of the medial e in litera- -> litra-
is probably illegitimate.
