142. Coarse gray sand, taken on outer border of the continental shelf. The 



sample consists of mainly ferruginous quartz sand, with no organic 

 material. Steamer Albatross; Station No. 2296; latitude 35° 35' 20" 

 north, longitude 74° 58' 45" west ; depth, 27 fathoms. October 20, 1884. 



143. Green mud, about 2 to 3 per cent organic material ( Globigerina ) , on the 



slope of the continental shelf. Steamer Albatross; Station No. 2233; 

 latitude 38° 36' 30" north, longitude 73° 6' 0" west ; depth, 630 fathoms. 

 September 12, 1884. 



144. Broken shells. All sand, much clear quartz sand, taken about 12 miles 



east of Newfoundland. Steamer Albatross; Station No. 2447; latitude 

 46° 26' 0" north, longitude 49° 42' 0" west; depth, 39 fathoms. June 

 25, 1885. 



145. From the bottom of the Atlantic on the edge of the continental shelf. 



Green mud and sand, with some organic fragments. These make about 

 one-fourth of the sample. The analysis applies to the inorganic part 

 of the sample only. Steamer Albatross; Station No. 2251; latitude 

 40° 22' 17" north, longitude 69° 51' 30" west. 



146. Fine white coral sand, one-fifteenth not sorted, organic, from some 15 



miles east of Yucatan. Steamer Albatross; Station No. 2358; latitude 

 20° 19' 0" north, longitude 87° 3' 30" west; depth, 222 fathoms. Jan- 

 uary 29, 1885. 



147. Coral sand, black specks, broken shells, mostly organic, but apparently 



mechanically sorted. Steamer Albatross; Station No. 2313; latitude 

 32° 53' 0" north, longitude 77° 53' 0" west; depth, 99 fathoms. Jan- 

 uary 5, 1885. 



148. Gray sand with black grains, containing about one-fourth organic ma- 



terial (Globigerina), taken from the upper border of the continental 

 shelf, about 60 miles from land. Steamer Albatross; Station No. 2614 ; 

 latitude 34° north, longitude 76° west ; depth, 168 fathoms. 



149. Green mud, containing 50 per cent inorganic material, taken on the slope 



of the continental shelf. Steamer Albatross; Station No. 2263 ; latitude 

 37° 8' 0" north, longitude 74° 33' 0" west ; depth, 4.30 fathoms. Octo- 

 ber 18, 1884. 



150. Dark gray mud. Gravel and sand, with some crinoid fragments, which 



are not counted in the grades of the analyses. On the upper slope of 

 the continental shelf. Steamer Albatross; Station No. 2586; latitude 

 39° 2' 40" north, longitude 72° 40' 0" west; depth, .328 fathoms. Sep- 

 tember 20, 1885.
