A difference between one thing and another, between one writing and another; a variance. 2. Discrepancies are material and immaterial. A discrepancy is immaterial when there is such a difference between a thing alleged, and a thing offered in evidence, as to show they are not substantially the same; as, when the plaintiff in his declaration for a malicious arrest averred, that the plaintiff, in that action, did not prosecute his said suit, but therein made default, and the record was, that he obtained a rule to discontinue.3. An immaterial discrepancy is one which does not materially affect the cause as, where a declaration stated that a deed bore date in a certain year of our Lord, and the deed was simply dated March 30, 1701.
