Residue, 40.57 per cent, greenish brown, consists of Minerals, [20.00], m. di. 
0.1 mm. quartz, hornblende, felspars, glauconite, and glassy fragments. Sili- 
ceous organisms [5.00], Diatoms, Radiolarians, and Sponge spicules, and casts 
of many of the organisms mentioned above. Fine washings {15.57], argillaceous 
and green amorphous matter, fragments of Diatoms, siliceous spicules, and fine 
mineral particles. 
3. Specimens of deposits procured around the Shores of the Greater and 
Lesser Antilles, 
The specimens are chiefly from depths between 100 and 1,000 fathoms, 
although a few are in depths less than 100 fathoms and a few are over 
2,000 fathoms. They are all in more or less close proximity to the 
coasts. The mineral particles are chiefly fragments of volcanic rocks or 
crystals derived from these, such as monoclinic and triclinic felspars, 
hornblende, augite, olivine, magnetic iron, and pumice ; along with a few 
fragments from ancient rocks, as quartz, tourmaline, mica, and epidote. 
Glauconitic grains were rare in these deposits, and phosphatic grains 
were likewise rare. In the deposits farthest from land the size of the
