I Lodskud No. 304 og 552 have Thermometrene an- 
givet en Tilvæxt af Temperaturen i de dybeste Lag. Me- 
dens 1 disse Tilfælder Bundtemperaturen kan bestemmes 
med Nojagtighed, da tre Thermometre have fulgt med 
Loddet, maa jeg anse deni det nest højere Lag registrerede 
Temperatur for usikker, ved No. 304 paa Grund af at 
Thermometret No. 46 længere oppe i Temperaturrækken 
synes at have vist for højt, ved No. -352 fordi No. 48 1 
andre Dybder stemme slet med andre Thermometres Re- 
gistreringer. 
Af ovenstaaende Tabel ser man, at samtlige de Iagt- 
tagelser, der kunne tjene som Bevis derfor, godtgjore, at 
Temperaturen i store Dybder overalt har ladet sig regi- 
Tallene 
1 den sidste Rubrik have samtlige negativt Fortegn: Tem- 
peraturaftagelsen er sterkere end Trykvirkningen. 
I Sognefjorden er dette ikke Tilfældet, da Tempera- 
turen ifølge Observationer med Negretti & Zambra's Vende- 
thermometer, udførte i 1879 af Capt. Knap, Oplodnings- 
dampskibet *Hansteen”, er constant i de større Dyb over 
Bunden. Ved Stationerne 1, 2, 3, 4 og 5 er der derfor 
ikke anbragt nogen Correction for Trykket. 
strere med Indexthermometrenes Minimumsindex. 
With soundings Nos. 304 and 352, the thermometers 
indicated an increase of temperature in the deepest strata. 
Whereas on these occasions the bottom-temperature could 
be accurately determined, 3 thermometers having accompa- 
nied the sounding-instrument, I must regard the tempera- 
ture registered in 300 fathoms above the bottom as doubt- 
ful, with sounding No. 304, since the thermometer No. 46, 
farther up in the series of temperatures, would seem to 
have registered too high, and with No. 352, because No. 
48 in other depths agreed very indifferently with the reg- 
istrings of other thermometers. 
From the above-given Table, we see that all observa-’ 
tions ‘calculated to serve as proof clearly show that the 
temperature in great depths could everywhere be registered 
with the minimum-index of the; index-thermometers. The 
figures in the last Column have all negative signs — the 
diminution of temperature exceeds the effect of pressure. 
In the Sognefjord this is not the case, the tempera- 
ture — according to observations with Negretti & Zambra’s 
inverting-thermometer, taken in 1879 by Capt. Knap from 
the Coast-Survey Steamer *Hansteen” — having proved 
constant in all the great depths. At Stations 1, 2, 3, 4, 
and 5 no correction has accordingly been applied for pressure.
