“Whereas it is inconvenient in practice to libel and conclude for general adjudication of lands as the alternative only of special adjudication, in terms of an Act of the Parliament of Scotland passed in the year one thousand six hundred and seventy-two:” It shall not be necessary to libel or conclude for special adjudication, and it shall be lawful to libel and conclude and decern for general adjudication without such alternative, anything in the said last-recited Act of the Parliament of Scotland, or in any other Act or Acts of the Parliament of Scotland or of Great Britain or of the United Kingdom of Great Britain and Ireland, to the contrary notwithstanding.
