The tonnage of the Spanish ships is taken from the official figures. Mr. Julian Corbett thinks that the Spanish system of measurement gave results much higher than those of the English, but after studying and applying the English and Spanish rules to the same ship-dimensions, the authors have come to the conclusion that the discrepancy in this respect was non-existent. The _Revenge_ by English measurement was 441 tons burden; by Spanish rules, apparently, 430. The main deduction, therefore, to be made from the Spanish figures is in respect of the difference between the Seville _tonelada_ (53·44 cubic feet) and the English ton (60 cubic feet). But even here it cannot be said that this can be applied to any but the Andalucian ships. On the whole, if a fair comparison be needed, perhaps about 10 per cent. should be deducted from the official Spanish figures; but nothing definite can be said.
