We remained here till the 28th of January; and, at taking leave of the Mandarin, Captain Gore, at his own request, gave him a letter of recommendation to the commanders of any other ships that might put in here; to which he added a handsome present. He likewise gave him a letter for the Bishop of Adran, together with a telescope, which he begged might be presented to him as a compliment for the services he had received, through his means, at Condore.
The harbour at Pulo Condore is in latitude 8° 40' 00" N.
Longitude, deduced from a great number
of lunar observations 105 18 46 E.
Dip of the north pole of the magnetic
needle 2 1
Variation of the compass 14 W.
High water, at the full and change
of the moon 4^h 16^m apparent time.
From this time the water continued, for twelve hours, without any visible alteration, viz. till 16^h 15^m apparent time, when it began to ebb; and at 22^h 15^m apparent time it was low water. The change, from ebbing to flowing, was very quick, or in less than 5^m. The water rose and fell seven feet four inches perpendicular; and every day the same whilst we continued there.

On the 28th day of January, 1780, we unmoored; and, as soon as we were clear of the harbour, steered S.S.W. for Pulo Timoan. On the 30th, at noon, the latitude by observation, being 5° 0' N., and longitude 104° 45' E., we altered our course to S. 3/4 W., having a moderate breeze from the N.E., accompanied by fair weather. At two in the morning of the 31st, we had soundings of forty-five fathoms, over a bottom of fine white sand; at which time our latitude was 4° 4' N., longitude 104° 29' E., and the variation of the compass 0° 31' E.
At one in the afternoon, we saw Pulo Timoan; and, at three, it bore S.S.W. 3/4 W., distant ten miles. This island is high and woody, and has several small ones lying off to the westward. At five, Pulo Puissang was seen bearing S. by E. 3/4 E.; and, at nine, the weather being thick and hazy, and having out-run our reckoning from the effect of some current, we were close upon Pulo Aor, in latitude 2° 46' N., longitude 104° 37' E., before we were well aware of it, which obliged us to haul the wind to the E.S.E. We kept this course till midnight, and then bore away S.S.E. for the Strait of Banca.
On the 1st of February, at noon, our latitude by observation was 1° 20' N., and the longitude, deduced from a great number of lunar observations taken in the course of the preceding twelve hours, 105° E. At the same time, the longitude, by Mr Bayley's time-keeper corrected, was 105° 15' E. We now steered S. by E.; and, at sun-set, having fine clear weather, saw Pulo Panjung; the body of the island bearing W.N.W., and the small islands, lying on the S.E. of it, W. 1/2 S., seven leagues distant. Our latitude, at this time, was 0° 53' N.
On the 2d, at eight in the morning, we tried for soundings, continuing to do the same every hour, till we passed the Strait of Sunda, and found the bottom with twenty-three fathoms of line. At noon, being in latitude, by observation, 0° 22' S., longitude 105° 14' E., and our soundings twenty fathoms, we came in sight of the little islands called Dominis, which lie off the eastern part of Lingen; and which bore from N. 62° W. to N. 80° W., five leagues distant. At this time we passed a great deal of wood drifting on the sea; and, at one o'clock, we saw Pulo Taya, bearing S.W. by W., distant seven leagues. It is a small high island, with two round peaks, and two detached rocks lying off to the northward. When abreast of this island, we had soundings of fifteen fathoms. During this and the preceding day, we saw great quantities of a reddish-coloured scum or spawn, floating on the water, in a southerly direction.
At day-light, on the 3d, we came in sight of the Three Islands; and, soon after, of Monopin Hill, on the island of Banca. At noon, this hill, which forms the N.E. point of the entrance of the Straits, bore S.E. 1/2 S. distant six leagues; our latitude, by observation, being 1° 48' S., and longitude 105° 3' E., the soundings seventeen fathoms, and no perceivable variation in the compass.
