"_Litera scripta manet_" (Vol. v., pp. 200. 237.).--I was intimate some
time since with a gentleman who had been a student in Maynooth College,
and who frequently used to quote the words "Litera scripta manet," with
the addition, "Verbum imbelle perit." This may give a clue to the source
of the phrase, which may be found probably in some ecclesiastical or
theological work of days gone by.
