portant scientific results of the expedition; but the whole of the observations are in course of publication, chiefly in the Philosophical Transactions of the Royal Society. Under the able supervision of Colonel Sabine, nearly all relating to terrestrial magnetism, which were transmitted by me, as opportunities offered, to England, have already appeared; and the magnetometric portion of them, in a separate volume, is in a forward state of preparation. The expense of these publications has been also defrayed by the government.
I am also indebted to Admiral Beaufort for the kind assistance he has given me in the construction of the plans and charts contained in these volumes; to Mr. Davis, of the Terror, by whom they were drawn from my original documents; and to the Messrs. Walker, for the accuracy and beauty with which they have been engraved.
Indeed, I am unable to express the gratitude I feel to those gentlemen who have so generously come forward to afford their gratuitous assistance in the publication of the accumulated labours of the Expedition: in their hands I feel assured that full justice will be done to the several subjects under their discussion, and that when all shall have been completed, I think it will be acknowledged that the Expedition has accomplished the more important objects for which it was sent forth.
