“This case came on upon cross motions to take the bill for confessed for want of an answer, and to dissolve the injunction. The defendant grounded his motion upon an answer sworn to by the defendant at Canton, in April last. It was objected to as an answer properly verified by oath, the only evidence of that fact being the certificate of three persons, witnesses to the signature of the defendant, who swore that they saw the defendant sign the same, and that he swore to the answer according to the laws of China.”
