at the coast more closely still, we find in about 29° 30, S. Lat. the
name Tortelduyff (Turtle Dove Island), to the south of Houtmans Abrolhos,
an addition to the chart dating from about 1624 [*****].

[* See the documents sub No. XI (pp. 14 ff.). If NORDENSKIÖLD had known
these documents, he would have withheld the second alinea on p. 199 of
his interesting _Periplus_.--The doubts, also, concerning Frederik De
Houtman's share in the discoveries on the west-coast of Australia,
expressed by COLLINGRIDGE (_Discovery_ p. 304), CALVERT (_Discovery_, p.
25), and others, are now likely to be set at rest.]

[** They were then held to lie in 28° 46'. On this point see also the
documents of PELSAERT'S shipwreck (No. XXIII, pp. 55 ff).]

[*** About this latitude, between 32° and 33° S. Lat., also De Houtman
and Dedel estimated themselves to be, when they first came upon land.
They afterwards ran on on a northerly course.]

So much for the highly interesting chart of Hessel Gerritsz of the year
1627. If we compare with it the revised edition of the 1618 chart, we are
struck by the increase of our forefathers' knowledge of the south-west
coast. This revised edition gives the entire coast-line down to the
islands of St. François and St. Pieter (133° 30' E. Long. Greenwich),
still figuring in the maps of our day: the Land of Pieter Nuyts,
discovered by the ship het Gulden Zeepaard in 1627 [*].
