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.
