to
gregory xvi.
supreme legislator of the papal world,
who in 1835
obliged and bound his subjects,
as well foreign as domestic,
with a new promulgation of his will,
in an index of prohibited books,
published with the express and entire
sanction of his authority
this attempt to extend the celebrity
of so valuable a boon,
and to do it more justice than has
been done by the
secretary of his sacred congregation —
is pertinently and gratefully
inscribed by
the author
