498 Mr. J. Murray on Oceanic Deposits examined 



had coated as well as filled the shell, so that we had both an external 

 and internal cast, the two linings connected by pillars representing the 

 foramina o£ the shell. 



18th August, 1874. Off Api, New Hebrides. 67, 70, and 125 fathoms. 

 The bottom in each case was a black volcanic sand, with which were 

 mixed Foraminifera and Pteropod shells. 



Sounding 212. 19th August, 1874. 2650 fathoms. Lat. 16° 4V S., 

 loug. 165° 20' E. A red clay containiug : — Much amorphous clayey 

 matter; many fine mineral particles, pumice, and black and brown 

 particles; a few manganese grains; one or two Eadiolaria; no 

 carbonate of lime. 



Sounding 213. 21st August, 1874. 2325 fathoms. Lat. 15° 58' S., 

 long. 160° 48' E. A red clay containing : — Much amorphous clayey 

 matter ; many small mineral particles, as pumice, mica, red mineral, 

 &c. ; a few remains of pelagic Foraininifera and a few Coccoliths. 



Sounding 214. 24th August, 1874. 2450 fathoms. Lat. 14° 7' S., long. 

 153° 43' E. A red clay containing : — Much amorphous clayey 

 matter ; many very fine mineral particles, as pumice &c. ; a few 

 broken remains of pelagic Eoraminifera ; a few manganese grains. 



Sounding 215. 25th August, 1874. 2440 fathoms. Lat. 13° 50' S., long. 

 151° 49' E. A red clay containing, in the upper half of the tube : — ■ 

 Much amorphous clayey matter; many fine mineral particles, as pumice 

 &c. ; a few Eadiolaria; no carbonate-of-lime organisms. In the lower 

 half of the tube a much lighter-coloured clay containiug': — Amorphous 

 clayey matter ; fine mineral particles ; a few Eadiolaria ; a great 

 many pelagic Eoraminifera and Coccoliths, which appeared to be 

 entirely absent in the upper layers. 

 The trawl brought up many pieces of pumice, varying from the size of 



a pea to that of an egg. 



Sounding 216. 27th August, 1874. 2275 fathoms. Lat. 13° 6' S., 

 long. 148° 37' E. A small quantity of bottom came up, which 

 indicated a grey clay containing : — Amorphous clayey matter ; fine 

 mineral particles; a few pelagic Eoraminifera, Coccoliths, and 

 Ehabdoliths. 



Sounding 217. 28th August, 1874. 1700 fathoms. Lat. 13° 42' S., 

 long. 146° 46' E. A Globigerina-ooze of a light brown colour con- 

 taining : — Many pelagic Foraminifera, Coccoliths, and Ehabdoliths; 

 amorphous clayey matter ; some fine mineral particles ; one or two 

 parts of Eadiolaria. 



Sounding 218. 29th August, 1874. 1400 fathoms. Lat. 12° 8' S., long. 

 145° 10' E. A Globigerina-oozQ of a light brown colour con-
