Forchham-finder i Søvandet, bliver hans Tal for Klornatrium ogsaa
noget forøget. I Vandprøver af samme Egenvægt og
Salt-gelialt. som de af mig undersøgte, erholder han som
Middeltal 2.75 pCt. Klornatrium.

By reason of the greater proportion of sulphuric acid
Forchhammer found in sea-water, his figures for chloride
of sodium are neçcessarily somewhat higher: I11 samples
of water with precisely the same amount of salt as those
examined by myself, lie determined the mean proportion
of chloride of sodium to be 2.75 per cent.
According to Table III. the specific gravity of the
Norwegian Sea is 1.0265; and 100 parts of the water
contain —
CåO MgO K40 CI SO,
0.0577 0.2203 0.0472* 1:932 0.2214.
The mean values, as computed by the last Table, for
the salts occurring in öcean^water. are as follows: —
Ca CO3 CaS04 MgSOl MgCl, KC1 NaHC03 NCI
0.002 0.1395 0.2071 0.3561 0.0747 0.0166. 2.682.
Hence. 100 parts of dry sea-salt contain —
Ca CO, CaS04 MgS04 MgCL KC1 NaCOs NaCl
0.057 4.00 5.93 10.20 2.14 0.475" 76.84.
Til Slutning vil jeg udtale min hjerteligste Tak til
Hr. Professor Waage for den Hjælp, han paa flere Steder
i mine Undersøgelser har ydet mig.
Kristiania, den 14de Februar 1880.
In conclusion. I beg to return Professor Waage my
most sincere thanks for the assistance lie kindly rendered
me when instituting the observations recorded in this
Memoir.
Christiania, Febr. 14th 1880.
