The printing will be commenced as soon as the number of subscribers is
sufficient to indemnify the authors for the inevitable outlay upon the
work; but should that number not be, at least approximately, obtained,
their intention must be abandoned. Gentlemen desirous of supporting
this undertaking will oblige the authors by an early intimation to
that effect.
