Abstract
Sir, It having been suggested, in a conversation at which I was present, that the ice of sea-water is not fresh; and that if the ice found near the poles be really so, it must probably be the ice of fresh water discharged into the sea from large rivers in those part: I thought the present cold weather afforded an opportunity too favourable to be lost, of ascertaining by experiment, whether the water obtained from the melted ice of sea-water be free from the taste of salt or not; of comparing its gravity with that of the sea-water, &c.; and of finding the degree of cold in which the latter begins to freeze: and I beg leave to lay before you an account of my researches in these matters, and of the methods I followed in making them.Keywords
