N.B. These tables shew the position of the vessel at noon, the variation of the needle distinguished by sr. when observed at the horizon at sun-rise; by ss., when observed at the horizon at sun-set; and by az., when it is the result of an azimuth observation; the degree of the thermometer according to Reaumur's scale (it was a thermometer with mercury), the height of the barometer at noon; the direction of the wind and the state of the weather.
