M E T EO EO LO G IC A L OBSERVATIONS.
TEJIPEKATUIIE OF .4IF AND SDEFACE OF THE SEA; HDMIDITY OF THE ATMOSPHEEE ;
WINDS, WKATHES, AND CLOUDS.
T h i s 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 Danieli/ hygrometer ; also three other
columns computed according to Mr. Daniell’s formula ; and a description ofthe clouds, winds,
and weather that prevailed.
The observations aremeaned for every five degrees of latitude, where the change of piace
admits of it ; but when otherwise, or when the observations ate 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.
