Such examined copy is admitted in evidence, because of the public inconvenience which would arise, if such record, public book, or register, were removed from place to place, and because any fraud or mistake made in the examined copy would be so easily, detected. 1 Greenl. Ev. §91; 1 Stark. Ev. 189-191. But an answer in chancery, on which the defendant was indicted for perjury, or where the original must be produced in order to identify the party by proof of handwriting, an examined copy would not be evidence. 1 M. & Rob. 189.
