Den anden Gruppe, der omfatter Observationerne fra 
Expeditionens sidste Tur, til Beeren-Eiland, Spidsbergen 
og Grønlandsisen, udviser ingen regelmæssig daglig Periode, 
som det vil sees af Figuren, Pl. II, Vanddampenes Tryk, 
1878, B. Den midlere Afvigelse fra Dagsmediet (5.”"34) 
er kun +0.””030, altsaa ikke større end MF i Gruppen 
A. Nogen daglig Periode er saaledes ikke paaviselig. Vi 
erindre, at den daglige Periode of Temperaturen ikke lod 
sig finde af denne Gruppes Observationer. 
Relativ Fugtighed. 
Til Beregningen af den daglige Periode for den rela- 
tive Fugtighed ere nojagtig de samme Observationer og 
Grupper benyttede som til Vanddamptrykkets. 
II 
The other group, comprising the observations taken 
on the last voyage of the Expedition, to Beeren Hiland, 
Spitzbergen, and the Greenland ice, gives no regular diurnal 
period, as will be seen from tbe figure in Pl. II, Force of 
Vapour, 1878 B. The mean deviation from the daily mean 
(5.7"34) is only + 0.”"030, accordingly not greater than MF 
in group A. Hence, a diurnal period cannot be found. 
As previously shown, the diurnal period of the temperature 
could not be determined from the this 
group.

Relative Humidity. 
For computing the diurnal period of the relative hu- 
midity, precisely the same observations and groups have 
been applied as for determining the force of vapour.
