And I do further Certify That by the Request of the Agents for managing the Controversy for the said Colonies I Delivered all the maps committed to my Care by the said Commissioners which were given in Evidence in the said Controversy, to Gerardus Bancker1 of the City of New York to be Copied he having been frequently employed by the said Commissioners for that purpose while they were engaged in the Execution of the said Commission. And that the several maps hereunto annexed appear by the Oath of the said Gerardus Bancker to be Copies of the respective originals so delivered to him and I do Certify further Certify That the said Copies of maps are Copies of all the maps so given in Evidence and committed to me by the said Commissioners except a map Intitled An accurate Map of North America describing and distinguishing the British Spanish and French Dominions on this great Continent according to the Definitive Treaty concluded at Paris 10th February 1763, also all the West India Islands belonging to and possessed by the several European Princes and States the whole laid down according to the latest and most authentic Improvements by Eman Bowen,2 Geographer to his majesty, which the Agents for both Colonies have agreed was unnecessary to be transmitted with the Proceedings, it having been given in Evidence only to shew how many miles were computed to a Degree at the time of making the said map.
