TABLE VI. 
METEOROLOGICAL OBSERVATIONS, 
TEMPF.KATUEE OF AIR AND SURFACE OF THE SEA; HUMIDITY OF THE ATMOSPHERE; 
WINDS, WEATHER, AND CLOUDS. 
This table contains the maximum, minimum, and mean temperature of the air for each 
day, deduced from observations made every two hours, with a thermometer freely exposed to 
the breeze ; the mean temperature of the surface of the sea, compiled from observations made 
every four hours by plunging a thermometer into a bucket of sea water immediately it was 
drawn up ; and the point of condensation as shown by Daniell’s hygrometer; also three other 
columns computed according to Mr. Daniell’s formula ; and a description of the clouds, winds, 
and weather that prevailed. 
The observations aremeanedfor every five degrees of latitude, where the change of place 
admits of it ; but when otherwise, or when the observations are made at any port, the average 
for that place is taken ; and when more than one month is passed between the parallels into 
which I have divided the table, the mean of the month is given.
