56° 46' N., longitude 168° 53' E., brought up by Lieut. 

 Brooke, with Brooke's lead. 



No. 2. Sea bottom, 1700 fathoms (10,200 feet), latitude 

 60° 15' N., longitude 170° 53' E., brought up as above, July 

 25th, 1856, and 



No. 3. Sea bottom, 900 fathoms, temperature (deep sea) 

 32° Saxton, latitude 60° 30' N., longitude 175° E. 



He says that "a careful study of the above specimens 

 gave the following results : — 



"First — All the specimens contain some mineral matter 

 which diminishes in proportion as the depth increases, and 

 which consists of minute, angular particles of quartz, horn- 

 blende, feldspar and mica. 



"Second — In the deepest soundings (No. i and No. 2) 

 there is least mineral matter, the organic contents (which are 

 the same in all) predominating, while the reverse is true of 

 number three. 



"Third — All the specimens are very rich in the siliceous 

 shells of the Bacillaria, which are in an admirable state of pre- 

 servation, frequently with the valves united, and even retain- 

 ing the remains of the soft parts. 



"Fourth — Among the Bacillaria, the most conspicuous 

 are the large and beautiful species of Cosciyiodisais. There are 

 also, besides many others, a large number of a new species of 

 Rhizosolenia, a new Syndendrhivi , a curious species of Chceto- 

 ceros with furcate horns, and a beautiful species of Asterom- 

 phahis with from five to thirteen rays, which Bailey proposed 

 to call Asternmphalus brookeii, in honor of Lieut. Brooke, to 

 whose ingenious device for obtaining deep soundings, and b}^ 

 whose industry and zeal in using, we are indebted for these 

 and many other treasures of the deep. 



"The specimens contain a considerable number of the 

 beautiful, siliceous shells of the Radiolaria. No Foramenifera 

 have been detected." 



In November, 1856, I made the personal knowledge of 

 Prof. Bailey when I visited him at West Point and spent sev-
