(They) have not done much worth mentioning, for at the place where the chart [*] they had with them, led them to expect an open passage, they did not find any such, so that they could not get to the island they wished to reach...[**]
[* It is highly probable that this is another allusion to a chart of the voyage of Willem Janszoon with the Duifken in 1605-1606, because other documents concerning this expedition of the Arnhem and the Pera put it beyond a doubt that they had on board a chart of the voyage of the ship Duifken. In that case the passage in the text proves that Willem Janszoon already suspected the existence of Torres Strait, since the "open passage" can hardly refer to anything else.]
[** The remaining part of the letter refers to the time when the two ships were still together, and contains nothing new.]
