_Post-Office about 1770._--Mr. Smith, in the notes prefixed to the
_Grenville Correspondence_, says several of Junius's letters appear to have
been sent from the same post-office "as the post-mark is '_peny_ post
payd,'"--a peculiarity of spelling not likely to occur often. Have any of
your correspondents letters of that date with a like post-mark? and, if so,
can they tell us _where_ posted?
