certainly indemnify Manila for the losses incurred by the lack of the Chinese silks. Among the papers accompanying this memorial are official certificates of the amounts of spice carried to Nueva España by the trading-fleets from Cadiz during 1723-32; the quantity of cinnamon in each has been already mentioned, cloves were not included in any of their cargoes, and pepper diminished from 54,804 libras in 1723 to none in 1732. Another document is the report of an investigation made at Cadiz as to the measures of bales and chests and of the churlo in which the cinnamon is transported; this last was found to measure 30 cubic palmos outside the vessel's hold, but 38 palmos when within it. Arquéo is defined as "the computation or estimate which is made of the bulk of the lading which the ship contains in its hold; this burden was measured by toneladas, each one of which contained 8 cubic codos, and each codo consisted of 33 dedos of the 48 into which the Castilian vara (which is commonly called 'the vara of measure') was divided. The tonelada, having as its [cubic] root two codos, or 66 dedos, contains 287,496 cubic dedos; dividing this number by 1,728, the number of cubic dedos in a cubic palmo, or quarter of a vara, each tonelada of arquéo is equivalent to 166 3/8 cubic palmos; from this it is deduced that if the ship is one of 1,000 toneladas, it will contain 166,375 cubic palmos, and in the same ratio for any other tonnage. As for the regulation of the spaces between decks [entrepuentes] by the capacity of their storerooms, no general rule could be given, on account of the great irregularity which was observed in them; for this matter was at the discretion of the shipbuilders, and according to the object for which the vessel was built."]
