Abstract
IN the office of the Coast Survey at Washington there are about 9,000 specimens of various kinds of marine animals which were brought up by the sounding lead from the sea-bottom, in the region between the shore of Florida and adjacent States and the outer edge of the Gulf Stream, and descending to a depth of 1,500 fathoms nearly. The dredge has been but comparatively little used along the coast of the United States, and that so many specimens were collected by the lead alone is due to the persevering care of the late superintendent of the survey, Prof. A. D. Bache, and to the instructions which he gave to the hydrographical officers. Of course, specimens brought up by the lead can include the smaller animals only, such as Foraminiferæ, Diatomaceæ, and such, like; for the larger animals, the dredge must be employed.
