Some remarks in reply to Dr. Daubeny;s note on the air disengaged from the sea over the site of the recent volcano in the mediterranean

Respecting the air in question, which Dr. Davy had found to consist of about 80 per cent, of azote and 10 oxygen, he had remarked that two views might be taken of its origin; the one, that it was of volcanic source; the other, that it was derived from the sea water, and merely disengaged by the heat of the volcano. Dr. Davy, rejecting the former of these views, had adopted the latter, for reasons, the validity of which was controverted by Dr. Daubeny; and the purpose of the present paper is to answer the objections urged against them, and to bring additional evidence in support of his opinion.
