from
Bouvier's Law Dictionary, Revised 6th Ed (1856)
MANNER AND FORM, pleading. After traversing any allegation in pleading, it
is usual to say "in manner and form as he has in his declaration in that
behalf alleged," which is as much as to include in the traverse, not only
the mere fact opposed to it, but that in the manner and form in which it is
stated by the other party. These words, however, only put in issue the
substantial statement of the manner of the fact traversed, and do not extend
to the time, place, or other circumstances attending it, if they were not
originally material and necessary to be proved as laid. 3 Bouv. Inst. p.
