general objection to evidence

objections of this character as vague and nugatory, and, if entitled to weight anywhere, certainly as without weight before an appellate court... Upon the offer of testimony oral or written, extended and complicated as it may often prove, it could not be expected, upon the mere suggestion of an exception which did not obviously cover the competency of the evidence, nor point to some definite or specific defect in its character, that the court should explore the entire mass for the ascertainment of defects.
