furnished to us by the office of the secretary for Nueva España, in order that this Summary [Extracto] might be drawn up and arranged, in obedience to the order of the Council. The series of the proceedings in regard to the 'Equivalent' [17] (which this 'Period x' comprises) remains, however, imperfect until they shall be concluded and ended by the advisory report of the Council and the decision of the king; but it seemed best not to wait for that, for the sake of facilitating, by this Summary, the more exact understanding of the gentlemen who are to express their opinions in regard to the 'Equivalent.'
