Formerly it was common to make two instruments exactly alike, and it was then usual to write both on the same parchment, with some words or letters written between them, through which the parchment was cut, either in a straight or indented line, in such a manner as to leave one-half of the word on one part, and half on the other. The instrument usually commences with these words, "This indenture," which were not formerly sufficient, unless the parchment or paper was actually indented to make an indenture 5 Co. 20; but now, if the form of indenting the parchment be wanting, it may be supplied by being done in court, this being mere form. Besides, it would be exceedingly difficult with even the most perfect instruments, to out parchment or paper without indenting it. Vide Bac. Ab. Leases, &c. E 2; Com. Dig.
