(66) Whenever the answer of the defendant shall not be excepted to, or shall be adjudged or deemed sufficient, the plaintiff shall file the general replication thereto on or before the next succeeding rule day thereafter; and in all cases where the general replication is filed, the cause shall be deemed to all intents and purposes at issue, without any rejoinder or other pleading on either side. If the plaintiff shall omit or refuse to file such replication within the prescribed period, the defendant shall be entitled to an order, as of course, for a dismissal of the suit; and the suit shall thereupon stand dismissed, unless the court, or a judge thereof, shall, upon motion for cause shown, allow a replication to be filed nunc pro tunc, the plaintiff submitting to speed the cause, and to such other terms as may be directed.
