Some of the organisms are maeroscopic. The mineral 
particles form a red-brown volcanic sand. Trawl line 
broke in heaving in. 
The deposits were in all these soundings similar to the 
above, the mineral particles being larger nearer shore. 
No deposit preserved ; the small quantity on the tube 
indicated a Globigerina Ooze. 
These two soundings are practically the same. The size 
of the mineral particles is a little less in the deeper 
sounding, viz., 630 fathoms, and here the pelagic Fora- 
minifera make up the greater part of the carbonate of 
calcium. The same remark holds good for all these 
soundings off the Canary Islands ; the deeper ones 
might be called Globigerina Oozes. 
No (ieposit preserved. 
This deposit resembles those of Stations VIIl.

The carbonate of calcium is made up for the most part 
of rounded fragments of Molluscs, Serpula, Echino- 
derms, Polyzoa, and Foraminifera.
