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. 4 M. & M. 2 5 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." 2 Salk. 658; 19 John. 49 5 Taunt. 707; 2 B. & A. 301; 8 Miss.
