As this Court stated in
Albert Appeal, 372 Pa. 13, 20, 92 A.2d 663, 666 (1952), "The doctrine of
judicial notice is intended to avoid the necessity for the formal introduction of evidence in certain cases when there is no real need for it, — where a fact is so well established as to be a matter of common knowledge." Accord,
Commonwealth ex rel. Duff v. Keenan, 347 Pa. 574, 582-583, 33 A.2d 244, 249 (1943) ("What is so well known as to be incontestable need not be proved formally."); See also
