Remarks. 



At about 3h. p. m. the 

 moon's Perigee. Onshore 

 the tide rose so much as 

 to destroy a large portion 

 of native huts situated on 

 the low country. The 

 ship's position was quite 

 landlocked and surround- 

 ed by high land, except- 

 ing in a Southerly direc- 

 tion, but none nearer 

 than 2 or 3 leagues, ex- 

 cept to the East, close 

 under which she lay. 

 Latitude 16° 07' N. ; 

 Longitude 108° 13' E. 



At 6h. 50m. Full moon.

 Barques Swallow and Rob Roy's Tyfoon of November, 1847. 



The Barques Rob Hoy and Swallow were both dismasted in this Cy- 

 clone, which appears to have crossed the China Sea from the coasts of 

 Luconia, about Point Capones, in a W. N. Westerly direction to Hainam. 



The following notice is from a newspaper. I have no further ac- 

 counts of these two vessels, and in the original, Laboan is printed for 

 Luban, evidently a mistake. 



The ship Sea Witch (from New York 14th August and Manila 24th instant,) 

 has on board the crew of the ship Ann and Jane ; that vessel having been 

 wrecked on the Island of Luban on the 8th instant (1847.) She was from 

 London for this port with a valuable cargo, all of which, with the ship, is totally 

 lost. Two of the crew were drowned ; and the remainder carried to Manila in 

 a Spanish schooner, and from thence to Hongkong in the Sea Witch.
