July 7th. The sum of the positive errors is lll.m4,
distributed over 10 days, or ll.m14 per day. The sum of the
negative errors is — 143.ffl6, distributed over 10 days, or
— 14.m36 per day. The average error is thus — 32.m3,

Figuren Pl. I, Luftens Temperatur 1877 A, viser, at
den observerede Curve springer temmelig meget paa begge
Sider af den beregnede. Det observerede Minimum ved
Kl. 3 p.m. synes ikke at have reel Betydning. Derfor er
Curven beregnet med kun 2 Led. MF = + 0.°06.
Efter Formelen beregnes
Minimum: — 0.°54,2A29ma.m.. Maximum: 0.°37, 2A l’" p.m.
Medium indtræffer: 7A 49m a.m. og 9A 7™ p.m.
Amplitude: 0.*91.
The figure in Pl. I, Temperature of the Air, 1877
A, shows that the observed curve diverges considerably on
both sides of that computed. The observed minimum at
3 p.m. would appear to have no real significance. The
curve has therefore been computed with only two terms.
MF = + 0.°06.
From the formula were computed —
Minimum — 0.°54. 2A 29™ a.m.; Maximum + ().°37, 2A 1™ p.m.
The Mean occurs at 7A 49m a.m. and 9A 7m p.m.
Total Range: 0.°91.

Observationer, som toges, medens Expeditionen befandt sig i den
Grønlandske Polarstrøms Omraade hvor Temperaturen
i Havet allerede i 20 Favnes Dyb er under 0° C. —, men

Observationerne for Juli 28 til August 5. 9 Dage.
For the second group, 1877, comprising the
observations taken within the limits of the Greenland Polar current.
— where the temperature of the sea at a depth of not
more than 20 fathoms is below 0° C., — but in water free
from ice, in more or less close proximity to the shores of
Jan Mayen, the observations applied are those taken from
July 28th to August 5th. 9 days.
