January 27. Passed close to windward of Botel Tobago Kim a 

 [Hungtow Island or Hungt'ou Hsii] and in the night hauled 

 to the southward around the south end of Formosa passing 

 betweed Gadd Rock [Kaot'ai Shih or Gaddo Yen] and Vele 

 Rete Rock [Ch'insing Yen] into the China Sea. 



January 29. Again in Hong Kong. No news of the Porpoise — 

 feared lost. Hancock still at Shanghai — being repaired. It had 

 suffered during the winter cruise. The schooner Fenimore 

 Cooper had also had a hard time. Lieutenant Hunter has died 

 on board the Hancock. Government has confirmed Captain 

 Rodgers in his command, and our Northern cruise is therefore 

 certain. 



The Vincennes stayed in Hong Kong to be overhauled. For 

 the first half-month I have been busily employed in describing 

 the new species collected on the late cruise. In doing this I am, 

 of course, confined to my room. The ship is undergoing an 

 overhauling, and the sound of the caulking mallets around and 

 over my head is no great help to patient investigation. I suc- 

 ceeded in bearing it however, with considerable sacrifice to health 

 and had the pleasure of handing to the Commodore descriptions 

 of eighty-one new species, which were sent home for publication. 

 Hancock and Cooper arrived during the latter part of the 

 month. They had been engaged in surveys on the Northeast 

 coast of China, chiefly in the Gulf of Pee-chee-lee [Chihli] and 

 about the mouth of the Pei-ho [Pai] River. 



March. In this month I recommenced marine researches. I did but 

 little dredging however, but confined my operations chiefly to 

 the shores or the Chinese fishing boats which are often quite 

 zoological thesauri. At the end of the month Hancock and Cooper 

 sailed for Loo Choo via coast of Formosa to seek tidings of the 

 Porpoise. 



April 6. Vincennes left Hong Kong. Commanded by Commodore 

 Rodgers; Wright, Botanist; Stimpson, Zoologist. 



April 11. N. Lat. 22°43'; E. Long. 116°20'. Dredged in China 

 Sea, fifteen to twenty fathoms, grey sand. 



April 12. N. Lat. 22°35'; E. Long. 116°53'. Having had one of my 

 largest dredge frames rigged with a canvas bag and a net bottom, 

 I tried dredging on a large scale this afternoon from the ship in 

 twenty-seven fathoms, sandy bottom. First two hauls rather 

 successful, a moderate quantity of sand being taken which proved 

 to be rich in annelides and mollusks. 



April 13. N. Lat. 22°56'; E. Long. 117°39'. Dredged in twenty-five 

 to thirty fathoms. 



April 19. Back at Loo Choo group.
