“ By the rules of common law it is certainly necessary that parties who sue as co-plaintiffs, alleging themselves to be partners, shall make proof of that allegation. The same is true of persons who are alleged to be copartners, and sued as such as defendants. By the statutes of Illinois the rule of law is changed in this respect unless a plea in abatement is interposed, or verified pleas are filed denying the execution of a writing set up. The statute rendered unnecessary in this case proof of the partnership or joint liability of either the plaintiffs or defendants. ”
