APPENDIX. 
twenty-four hours ; the total number on the sick-list is thirty-four, with 
twenty-eight cases of dysentery and five of fever. The thermometer has 
been ranging at 86° since we left Batavia, with calm and liglrt airs ; we 
are out twenty days, and are but six hundred miles from Batavia. Last 
night we had the most tremendous thunder, lightning, and rain." 
The Potomac arrived at Lintin (Cliina) on the 20th of May, with 
twenty-nine on the sick-list, after a most tedious passage of thirty-nine 
days. After the 2d of May we fell in with moderate breezes, which con- 
tinued until our arrival at Canton ; after which the number of sick 
diminished daily. There were one hundred and fifty cases of dysentery 
in the Java and China Seas, out of which there were thirteen deaths, — a 
proportion truly small, when compared with the number of deaths in 
other vessels while in those seas. , We,remained at Lintin seventeen 
days, during which the thermometer had a daily average of 80°, with a 
regular Seabreeze, which well ventilated the ship. The average number 
on our sick-list was twenty-six ; three fourths of which were chronic 
cases of dysentery, and several cases of bilious fever. 
Canton was formerly considered the most unhealthy district in China, 
but at present it is one of the most healthy. Tlie Lintin fleet, which 
usually remain stationary for many months, enjoy good health ; dysen- 
teries and fevers are the prevailing diseases. Tlie Chinese and natives 
of British India have so little vitality in their lower extremities, that frac- 
tures and ulcerations of those parts are very difficult to cure — a circum- 
stance to be attributed to the debilitating effects of the climate. 
Sailed on the 5th of June for the Sandwich Islands, with thick foggy 
weather and a fresh breeze. On the 9th, during a gale, with the ther- 
mometer at 80°, there were two deaths — cases of chronic dysentery. 
During the passage there was much rain and tliick heavy weather ; the 
easting was made between the thirty-fourth and thirty-sixth degrees of north 
latitude, witli the thermometer ranging at 72°, and the average on the 
sick-list twenty-five, during the passage. 
Arrived at Oahu, Sandwich Islands, on the 23d of July, after a passage 
of forty-eight days. The character of the diseases had mucli changed ; 
during our passage there were no new cases of dysentery, but the old cases 
convalesced slowly. Pleurisies, catarrhs, and intermittent fevers took the 
place of the enteric diseases, and yielded more readily to medical treatment. 
The Potomac remained twenty-three days at tire Sandwiclr Islands, 
during which time the thermometer stood at 79°, and barometer at 29.90. 
The crew were allowed to go on shore ; in consequence of which the sick- 
list was swelled by the men who had been on shore. On the day of our 
arrival there were seventeen on the list, and on the day of sailing it had 
increased to twenty-six. The climate of the Sandwich Islands is good ; 
the foreign residents enjoy good health ; the natives are large, corpulent, 
and of a lymphatic temperament. Their usual diet consists of the arum 
MACULATUM, or wakc-robin, which is cultivated, and attains a great size ; 
and contains a large portion of fecula, out of which they manufacture 
dence between the tropics would prove beneficial. The disease was so far advanced 
that a change of clime could not arrest the progress of the disease. His conciliating 
manners, cheerfulness of disposition, and intelligence, gained him many friends : he died 
regretted by all who enjoyed his acquaintance.
