“46. A semi-circular copper plate, whose case is curved in such a manner as to form a parallel. Through the middle of the plate runs a meridian, having in its centre a small screw, which was formerly moveable, but now fixed by rust. On the left or on the west side of the meridian are drawn nine arcs, having their centre in the point of intersection of the meridian and parallel. On these arcs the degrees are indicated by ciphers, and between these arcs are found the Dutch words: Wassende Noordoostersche, Afgaande Noordoostersche, Wassende Noordwestersche, etc. It is difficult to say in what manner this instrument was used, but probably it is an instrument that has served for examining and determining the variations of the compass. If I dare express my opinion, I should say, that this is the instrument which Plancius, the master of Barendsz, invented to calculate the longitude at sea. Plancius was at that time much occupied with his theory of determining the longitude at sea, by means of the variation of the needle. For farther details see the work entitled: ‘Rise of the Dutch power in the East Indies,’ volume i, p. 86. According to Plancius there existed 8 meridians, under 4 of which there was no variation, and under the 4 others a maximum variation took place. Calculating upon these data Plancius imagined that the true longitude could be found. He therefore adapted a copper plate to the astrolabe employed at that period, and the object found by Carlsen is probably this very copper plate, the only one now extant. “47. The handle of a sword beautifully formed. A similar handle is represented on drawing 61, letter B in the work of Mr. D. van der Kellen, Jr., entitled: ‘Antiquities of the Netherlands.’ “48. A sword with ditto handle. “49. The point of a sword. “50. A part of a spear, with iron spearhead. “51. Ditto head without wood. “52. The point of a halberd. A nearly equiform halberd is represented in the illustration. ‘The exact manner of the house wherein we wintered’.
