Generally a party could not testify at common law, but he could give in evidence his books of account supported by his suppletory oath. Eastman v. Moulton, 3 N.H. 157. The fact that the other party was an executor or administrator did not affect this right. By Gen. Laws, c. 228, s. 13, it is provided that a party may testify in any civil cause. Sections 16 and 17 of the same chapter provide that neither party shall testify when the adverse party is an executor, administrator, or insane person, unless the executor, administrator, or guardian elects to testify, except it clearly appears to the court that injustice may be done without his testimony. Section 16 is intended as an exception to section 13, and not as an exception to the right which the party had at common law to give in evidence his books of account supported by his oath. The law in this respect remains as it was before any statute was enacted upon the subject. Moore v. Taylor,44 N.H. 370, 374; Swain v. Cheney, 41 N.H. 232; Page v. Whidden, ante, p. 507; Peirce v. Burroughs, ante, p. 512.
