The only difference between the above form and one for the reception of
_corrected_ readings will be the dispensing with the column for the
attached thermometer, and placing under the word Barom. "corrected."


II.--TIMES OF OBSERVATION.

There can be no question that the greatest amount of information, the
accuracy of the data supplied, and in fact every meteorological element
necessary to increase our knowledge of atmospheric waves, may be best
obtained by an uninterrupted series of _hourly_ observations made on
board vessels from their leaving England until their safe arrival again
at the close of their respective voyages; but from a variety of
circumstances--the nature of the service in which the vessels may be
employed, particular states of the weather, &c.--such a course of
unremitting labour cannot be expected; it is therefore necessary to fix
on some stated hours at which the instruments before particularized
should be regularly observed throughout the voyage, and their
