ding of 4 fathoms was obtained, and a second sounding showed a depth of 15 fathoms.

North Coast of Banca.-A reef, with only 74 feet water, lies about 13 miles from the shore, and nearly midway between assock point and Cape Tuen. From the shoal, Crassock point bears W. by N. ¦ N., Pulo Pongoh off Čape Tuen S.E.4 3. and Pakoe point S. by E.

Banka Strait.-A rock, with 12 feet over it at low water, lies about 2 cables northward of the Hadjie reef, with Lang Bersiap, the eastern point of Banca island, bearing N. E., and Kalian point lighthouse E. N.

Gaspar Strait.-A reef has been discovered lying N.N.W. 32 miles from the Belvedere rock, also 17 miles distant from pur island, and 28 miles from Brekat point on Bauka island. The position given is in Int. 2° 8' S., long. 107° 1′ 15′′ E.

A reef, with only 6 feet water, lies off the northern end of Pulo Leut. From a position three-quarters of a cable north- *d of the shoal, the northern point of Pulo Leat bore S.W., and the eastern point of Pulo Anak, or Selagin, S. by E. E. Carimata Strait.-A reef, situated on the north-east coast of Billiton, and shown as "doubtful" on the charts, has been and to list. It dries in one spot, and is in lat 2° 37′ S., long. 108° 18′ E.

A bank that dries has been observed off the east coast of Billiton; from the bank Slandak island bears S.W. § W., Cantong island W. by S., and Boesong Madau island N.W. W.; the position given is in lat. 2° 59′ S., long. 108° 1′ E. A reef, with about 6 or 7 feet water, lies near the assigned but doubtful position of a shoal anned Admiral Protet; from Slandok island bears W. & S., and Liendorg, one of the Scharvogel islands, S.S.W., the position given is in lat. 2° 59′ S.,

103° 38′ E.

Greig Shoul.-Careful examination has shown that the position of this danger, off the western coast of Borneo, is lat. 0° 30'S., and long. 103° 25′ E.; from the shoal Panambungan island bears ES.E., and the peak of Carimata island S.S.E. ¡L. The shoal is circular in shape, about 14 cabies in diameter, and has 8 feet water over the shoalest part.

Jasa Sea.-E. † N. from the south point of Peblakan or West, island, distant about 34 miles, is a reef of coral and stone; mis reef extends about one cable north and south, and 24 cables cast and west; there is about 4 feet water over the shoalest *t, and from 4 to 5 fathoms avonud the reef; from it the extremes of Rangat island bore N.W. 4 N. and N.W. by N. spectively.

•

A zeef also, on which the sea breaks heavily, extends a distance of about 2 cables. (by estimation) from the north and : -th-east sides of Bangat island.

Careful examination has shown that the Siren bank, to be found on some charts in lat. 5° 19′ 30′′ S., long. 100° 34′ 45′ E, does not exist, and that no danger has been found near the assigned position.
