The only accounts accessible are in Cabrera (see Philippson's "Estimate of the Revenues of Spain," in his Henrich IV. and Philipp III., vol. ii. p. 44), and relate only to the years 1599-1610. The amounts given are not the total yield of the American mines, which is out of the question, but the amount of metal brought yearly to Spain by the Silver Fleet. The amounts (without distinction of the metals) were as follow:— 15998,000,000 Ducats. 16009,926,192 Ducats. 160010,000,000 Ducats. 16011,000,000 Ducats. 160210,000,000 Ducats. 16037,000,000 Ducats. 160414,500,000 Ducats. 16069,000,000 Ducats. 16064,500,000 Ducats. 160712,200,000 Pesos. 16089,000,000 Ducats. 160910,600,000 Ducats. 161010,000,000 Ducats.

Such is the statement of the proclamation itself. The difference between the ratios as there proclaimed and the ratios given in the table, pp. 40 and 69, is presumably due to the calculation being made on the mark of pure metal. For the character of these figures of ratios see the Preface.
