Salt water.
Immediately after the close of the volumetric experiments
the latent heat was determined of the water-samples IV, V &
VI. In the following table I give also a description of some
determinations on a watersample taken by Mr. Tornoe from
the surface of the arctic sea, south-east of Jan Mayn, 68° 32’
Lat. 6° 26’ Long. W. G., and kindly forwarded to me, and of
fresh water from the surface, formed by the melting of the
sea-ice at Pitlekaj.

water. Moreover I have hitherto only published these results in the Swedish
language (Ofversigt K. V. A. Forh. 1878) and especially wish to correct an
inadvertence in the description of exp. 2, where an erroneous number,
relating to an unsuccessful experiment, was inserted in the original instead of
the right one [1.8027 grammes of water].
