derived from three sources : First, from the records of the 

 previous voyages referred to in the instructions ; secondly, 

 from the record of Tasman's expedition of 1642 ; and thirdly, 

 from the records of the expedition of 1644. With regard to 

 the first of these sources, the recital of the previous dis- 

 coveries in Nova Guinea and the southland, and the, 

 instructions as to what -was to be done in regard to connecting 

 them could not have been understood, unless charts were 

 furnished showing the relative positions, and from these 

 charts the eastern side of the Gulf of Carpentaria, the north- 

 eastern part of Arnhem's Land and De Witt's Land, 

 Endraght Land, D'Bdel's Land, Leeuwin Land, and Peter 

 Nuyt's Land would be laid down. With regard to the 

 second source of information, an examination of the chart 

 will show that the original of it was made by some one who 

 had access to not only to Tasman's chart but also to his 

 -journal of the voyage of 1642-3, as the notes made on the 

 north coast of Guinea are similar to those contained in the 

 journal. When all the information to be obtained from 

 these two sources was laid down upon the chart it would be 

 as complete as it now is with the exception of the new land 

 discovered in the course of the voyage of 1644. And the 

 coast line of this new land, and the pricked line of the 

 passage made while discovering it, is all that Jacobsz refers 

 to in his central inscription. 



Another argument in favour of the inscription being a 

 copy of Jacobsz's attestation of the chart, and not an 

 independent subsequent insertion of Bowrey, is that the name 

 of New Guinea is applied to the new discovered land. Very 

 shortly after the expedition of 1644 the newly-discovered land 

 was called New Holland, and if Bowrey had written an 

 independent title to his copy he would probably have thus 

 named it. Dampier, who was on this coast in 1688, and again 

 in 1699, always calls it New Holland. 



It is evident that the Dutch authorities made no secret of 

 Tasman's discoveries on this Toyage, but that charts of it 

 were published, or at least allowed to be copied. It is 

 probable that Bowrey was thus allowed to make the copy in 

 the Sloane collection. Dampier had a copy with him during, 

 his expedition of 1699, when he was in command of one of 

 the king's ships. It evidently was similar to the one before, 

 us, for he complains of Tasman's (Mr. Tasman he politely calls 

 him) inaccuracies in latitude. He gives two latitudes from 

 the charts he refers to, one being that of the Abrulhos, which. 

 he mentions as erroneously laid down at 27 deg. 28 min. 

 south, and the other being the Archipelago, now called after 

 Dampier, which he says Mr. Tasman lays down in 19 deg. 

 50 min. instead of 20 deg. 21 min. south.
