There are many cases, however, in which a party to a suit has been admitted to prove facts not immediately connected with the issue. Thus, the service of notice to produce papers, may be proved by a party. (Jordan v. Cooper, 3 S. & R. 675.) So, the loss of a bill of exchange may be proved by the plaintiff, in an action against the acceptor, its previous existence having been proved. (Meeker v. Jackson, 3 Yeates 442.) So of a lottery ticket. (Snyder v. Wolfley, 8 S. & R. 328.) So, in Dehaven v. Henderson, post, p. 424, a plaintiff was admitted to prove the loss of an order given to him by the adjutant-general, for the restoration of property seized by the defendant, to let in evidence of its contents. So, a plaintiff has been admitted to prove the death of a subscribing witness to a deed, in order to let in evidence of his handwriting. (Douglass v. Sanderson, 2 Dall. 116, s. c. 1 Yeates 15.) But he is not competent to prove the handwriting of a witness to a deed (Peters v. Condron, 2 S. & R. 80); nor to prove the handwriting of a person (since dead) by whom the entries in his book were made. (Karsper v. Smith, 1 Bro. app. liii.)
