    [Extracted from the American Jour, of Science and Arts, 2nd Series, Vol. XVII, March, 1854.] made by the U. S. Coast Survey near the Atlantic coast of the United States* I made known that the soundings along the coast, from the depth of 51 fathoms S. E. of Montauk Point, to 90 fathoms S. E. of Cape Henlopen were chiefly made up of vast amounts of Foraminiferous shells, rivalling in abundance the de- posits of analogous fossil species which I had proved to compose immense beds under the city of Charleston, S. C. The facts were also mentioned that none of the species found in the soundings belong to the littoral genera of the group Aga- thistegnes of D’Orbigny [Plicatilia^ Ehr.) and that they also differed from those found in the tertiary deposits of Maryland and Virginia. These facts were confirmed and extended by the ob- servations of P. de Pourtales in liis Report to Prof A. D. Bache, on the distribution of Foraminiferse on the coast of New Jersey as shown by the off-shore soundings of the U. S. Coast Survey.f In this paper Mr. Pourtales states that “the greatest depth from which specimens had been examined is two hundred and sixty-seven fathoms, and there the Globigerina are still living in immense numbers.” He adds that the region of Globigerina ex- tends to a depth not known. I am indebted to that zealous cultivator of science, Lt. Maury of the National Observatory, for an opportunity to examine the deep sea soundings made by means of Brookes’s lead on board the U. S. Dolphin by Lt. Berryman. These soundings proved to be of great interest and furnished results which have an im- portant bearing upon Geology and Physical Geography, * See Smithsonian Contributions to Knowledge, vol. ii, Art. 3. f See Proceedings of American Association for the Advancement of Science, 1860, p. 84.
