On the eastern side, we have in every respect greater inaccuracy; but for the present we deal only with the question of latitude. For the sake of convenience, our reduction of Rotz’s map is made to terminate at the point where the eastern coast line of “the londe of Java terminates,” namely in the sixtieth degree, a parallel far exceeding in its southing even the southernmost point of Tasmania, which is in 43° 35´; but if we look to the Dauphin map, we find that about ten degrees of the southernmost portion of the line is indefinite, and it must not be forgotten that for the Portuguese this was the remotest point for investigation, and consequently the least likely to be definite. There is, however, strong reason for supposing that the eastern side of Tasmania was included within this coast line. With respect to longitude, it may be advanced that with all the discrepancies observable in the maps here presented, there is no other country but Australia lying between the same parallels, and of the same extent, between the east coast of Africa and the west coast of America, and that Australia does in reality lie between the same meridians as the great mass of the country here laid down. In Rotz’s map we have the longitude reckoned from the Cape Verde islands, the degrees running eastward from 1 to 360. The extreme western point of “the Londe of Java” is in about 126° (102 E. from Greenwich), whereas the westernmost point of Australia is in about 113° E. from Greenwich. The extreme eastern points of “the Londe of Java” is in about 207° (or 183° E. from Greenwich). The extreme eastern point however is on a peak of huge extent, which is a manifest blunder or exaggeration. The longitude of the easternmost side, excluding this peak, is in about 187° (or 163° E. from Greenwich), whereas the easternmost point of Australia is in something less than 154° E. from Greenwich. The difficulty of ascertaining the longitude in those days is well known, and the discoveries which these maps represent were, in all probability, made on a variety of occasions, and had a continuous line given to them on maps, not so much as an exact, but as an approximative guide to subsequent explorers. It were hard indeed, therefore, if sufficient concession were not made to the pioneers of maritime exploration, for the reconciliation of these comparatively light discrepancies, when inaccuracies as striking are observable in surveys made as late as in the eighteenth century. Thus in taking a general survey of the outline of this immense country, we have this one striking fact presented to us, that the western side is comprised between exactly the same parallels as the corresponding side of Australia, allowance being made for the conjunction of Java, while the eastern side presents the same characteristic as the eastern side of Australia in being by far the longest.
