For 187li faaes Middel af C = + U».287. Middel af
t = -j- 11°.I2. For denne Temperatur giver Formelen
for 1877 : 4- 0°.208, Formelen for 1878: -f 0».2;l2. og den
fælles Formel: 4 0».269.
Da Tliermoineter No. Il giver MF = + 0".UD8. er
dette Thermometer ikke saa paalideligt som No. T.
Til Bestemmelsen af Trvkcorreetioneii haves følgende
Iagttagelser.

From the comparisons for 1877. we have
- C = l".2 4
n.N = 9 X 0".02 — 4 0.18
i C — 11. X = + 1 .06
it =62 .6
C = 4 0°.02 -j- o.oiöq t.
For 1878. we have
- C = + ’"-77
11. N = 10 X o°.n5 = -f i .15
2 C — n. N = 4 o°.62
2 t = 39
C = 4- o°.ii5 + o .0159 t. MF = + o".oq2
For 1876, the mean of C = j 0°.287, the mean of
t = llu.l2. For this temperature, the formula for
1877 gives + 0°.208; the formula for 1878 + 0°.292; and
the joint formula -j- 0(,.2ö9.
As Thermometer II gives MF = + 0°.()98, this
instrument is not so trustworthy as No. I.
For determining the pressure-correction. I had the
observations in the following Table.

Da MF af Trykcorrectionerne er minclre end MF
af Skalacorrectionerne, ere aabenbart Aflæsningerne af No.
II i 1878 sikkrere end det antydes af denne sidste.
Den samlede Correction for No. II bliver altsaa
4 o°.o83 -f- 0.0158 t — 0.000177

For 1000 fathoms c = — o0.177

The mean error of the pressure-corrections being less
than the mean error of the scale-corrections, it is
evident that the readings of Thermometer No. 1.1 in 1878
are more trustworthy than indicated by the last error.
The total correction for No. II is accordingly
4 o".o83 -(- 0.0158 t 0.000177 h.
