The observations principally sought for being
those of the unaided eye on wind and weather, are
so few and simple that they may all be contained
in two columns-A NJ. and p. Min each of which
should be given the force and direction of the
wind and the state of the weather at the time of
observation. One sheet of paper, with thirty-one
horizontal lines will last a month-the observer
taking care at the end Of each day to describe on
the back OF the sheet the weather that has OBJ.
tanned for the last twenty-four hours, with such
further remarks as the memorandum suggests.
Those who have instruments may record their
readings each observer in his own peculiar way if
there be any difficulty with regard to the plan Of
projecting them in a table Of engraved squares, as
recommended in the "notes." This table is incon.
veniently large for publication here.
