] 150 fathoms, 53º.6; at 100 fathoms, 56º.7; at 50 fathoms, 57º.6; at 2 fathoms, 58º.7; and at the surface, 59º.7: the new thermometers agreeing very satisfactorily in their indications with those we had formerly used, when sent down together to several depths less than 600 fathoms. From these experiments it would appear that the mean temperature of the ocean was not attained; and for this purpose it would be necessary to descend below 800 fathoms in this latitude. The temperatures obtained at the several different depths were in each case about a degree higher than those taken in the same parallel in the Atlantic, and differing to very nearly the same amount from some obtained by Sir Edward Belcher in 32º 46′ N. latitude, and 152º W. longitude, and of which he kindly furnished me an account, when I met him at the Cape, in April, 1843. The following table will show the comparison at these three widely different positions.

We were at the time of these experiments about two hundred and seventy miles from the islands called the Three Kings, off the north end of New
