In all actions upon the case and other pleadings, wherein the party claiming may now by law allege his right generally, without averring the existence of such right from time immemorial, such general allegation shall still be deemed sufficient, and if the same shall be denied, all and every the matters in this Act mentioned and provided, which shall be applicable to the case, shall be admissible in evidence to sustain or rebut such allegation; and that in all pleadings to actions of trespass, and in all other pleadings wherein before the passing of this Act it would have been necessary to allege the right to have existed from time immemorial, it shall be sufficient to allege the enjoyment thereof as of right by the occupiers of the tenement in respect whereof the same is claimed for and during such of the periods mentioned in this Act as may be applicable to the case, and without claiming in the name or right of the owner of the fee, as is now usually done; and if the other party shall intend to rely on any proviso, exception, incapacity, disability, contract, agreement, or other matter herein-before mentioned, or on any cause or matter of fact or of law not inconsistent with the simple fact of enjoyment, the same shall be specially alleged and set forth in answer to the allegation of the party claiming, and shall not be received in evidence on any general traverse or denial of such allegation.
