and marked out, in accordance with the method determined upon by the astrologers, pilots, and sailors, and others abovesaid, and appointed as abovesaid, within the period of the first ten months reckoned from the date that either of the parties notified the other.  And should it prove that the land thus found is not cut by the said line, a declaration of its distance from the said line shall be given, both on our own part and that of the said most serene King, our brother.  They shall not, However, neglect to make the said declaration regarding any island or mainland which shall be found afterwards, during the period, nearer the said line.  And in doing the aforesaid, they shall not neglect to observe the manner aforesaid, whenever any island or mainland is found in the neighborhood of the said line as aforesaid, and up to the said time of the said ten months after the notification of one party by the other, as aforesaid.  It is our pleasure in this our letter to postpone and defer the departure of the said caravels and persons, notwithstanding the limit set and determined in the above-mentioned treaty in regard to it.  And we therefore are pleased and consider it advantageous—­for the better notification and declaration of the division of the said sea made by the said treaty between ourselves and the said King, our brother; and in order that both our subjects and natives and the subjects and natives of the said King our brother may be better informed henceforth as to the regions wherein they may navigate and discover,—­to order (as in truth we shall order), under severe penalties, that the line of the said division be placed on all hydrographical maps made hereafter in our kingdoms and seigniories by those journeying in the said Ocean Sea.  This line shall be drawn straight from the said Arctic to the said Antarctic pole, north and south, at the distance of the said three hundred and seventy leagues west of the Cabo Verde islands, as aforesaid, being measured as determined unanimously by the said astrologers, pilots, and sailors meeting as abovesaid.  And we purpose and stipulate that neither this present letter nor anything contained herein, be prejudicial in any manner to the contents and compacts of the said treaty, but rather that they, all and singular, be observed throughout in toto without any failure, and in the manner and entirety set forth in the said treaty; inasmuch as we have caused the present letter to be made in this manner, simply in order that the said astrologers and persons shall assemble and, within the said time, shall determine the order of procedure and the method to be observed in making the said line of demarcation, and in order to postpone and defer the departure of the said caravels and persons, until the said island or mainland, whither they must go, is known to have been found in each one of the said parts, and in order to command that the line of the said division be placed on the said hydrographical maps,—­all of which is set forth most fully in the above.  We promise and asseverate on our kingly faith and word, to fulfil and observe all of the foregoing, without any artifice, deceit, or pretense in the manner and in the entirety set down in the above.  And in confirmation of the above, we cause this our letter to be given, signed with our names, and sealed with our leaden seal hanging from threads of colored silk.
