For 1877 har jeg reduceret Kviksolvpiezometrets
Aflæsninger med en Trykcorrection af i0.4O5 per 1000
Favnes Tryk. efter en derefter construeret grafisk Tabel.
Med denne faaes MF rr + 0°.078.

1878. Marts 8 blev Kviksolvpiezometret
sammenlignet med Normalthermometret og dets Nulpunkt bestemt
paa det meteorologiske Institut i Christiania. Hvert T;u
beror paa 4 Observationer.
From the total number of observations we have

For 1877. 1 have reduced the readings of the
Mercury-Piezometer. with a pressure-correction of -f i0.4O5
per 1000 fathoms, according to a diagram-table
constructed for that purpose. With this. MF r= + o".o78.
Hence, for 1877. the Mercury-Piezometer gives

1878, March 8, the Mercury-Piezometer was
compared with the Standard-Thermometer and its zero
determined at the Meteorological Institute in Christiania. Each
figure is based 011 4 observations.
