A disagreement or difference between two parts of the same legal proceeding ,
which ought to agree together .
Variances are between the writ and the declaration ,
and between the declaration and the evidence .
2 .-
1 .
When the variance is a matter of substance ,
as if the writ sounds in contract ,
and the other in tort ,
and e converso ,
or if the writ demands one thing or subject ,
and the declaration another ,
advantage may be taken of it ,
even in arrest of judgment ;
for it is the writ which gives authority to the court to proceed in any given suit ,
and ,
therefore ,
the court can have no authority to hear and determine a cause substantially different from that in the writ .

But if the variance is in matter of mere form ,
as in time or place ,
when that circumstance is immaterial ,
advantage can only be taken of it by plea in abatement .

2 .
A variance by disagreement in some particular point or points only between the allegation and the evidence ,
when upon a material point ,
is as fatal to the party on whom the proof lies ,
as a total failure of evidence .
For example ;
the plaintiff declared in covenant for not repairing ,
pursuant to the covenant in a lease ,
and stated the covenant ,
as a covenant to "
repair when and as need should require ;"
and issue was joined on a traverse of the deed alleged .
The plaintiff at the trial produced the deed in proof ,
and it appeared that the covenant was to "
repair when and as need should require ,
and at farthest after notice :"
the latter words having been omitted in the declaration .
This was held to be a variance ,
because the additional words were material ,
and qualified the effect of the contract .
