ALBATROSS EXPLORATIONS. 505 
[3] 
hard clay resemble large angular blocks of stone, but when cut with a 
knife they have a consistency somewhat like hard castile soap, and in 
sections are mottled with lighter and darker tints of dull green, olive, 
and bluish gray. When dried they develop cracks and break up into 
angular fragments. This material is genuine clay, mixed with more or 
less sand, showing under the microscope grains of quartz and feldspar 
with some scales of mica. More or less of the shells of Globigerina and 
other foraminifera are contained in the clay, but they make up a very 
small percentage of the material.* 
LIST OF STATIONS OCCUPIED BY THE “ ALBATROSS” IN 1883. 
The following abbreviations are used to indicate the character of the 
bottom. They are the same as those used by the United States Coast 
Survey with a few additions desirable for greater precision:

In the following list the character of the bottom is not always given 
as in the original record, for in some cases colors or other qualities have 
been omitted, when unimportant, for the sake of condensation. In other 
cases additions or alterations have been made based on the materials 
actually brought up in the dredge or trawl, often in large quantities :
