EXHIBIT, practice. Where a paper or other writing is on motion, or on other occasion, proved; or if an affidavit to which the paper writing is annexed, refer to it, it is usual to mark the same with a capital letter, and to add, " This paper writing marked with the letter A, was shown to the deponent at the time of his being sworn by me, and is the writing by him referred to in the affidavit annexed hereto." Such paper or other writing, with this attestation, signed by the judge or other person before whom the affidavit shall have been sworn, is called an exhibit. Vide Stra. 674; 2 P. Wms. 410; Gresl. Eq. Ev. 98.
