THE DEPOSITS OF THE SEA-BOTTOM. 



Section I. 



On the General Qualities of the Bottom-Specimens, their Colour, 

 Consistency, etc., as well as their Classification. 



See the charts on pi. i and 2. 



Before entering upon the examination of the particular ingredients of the specimens, I must 

 give an account of their macroscopic qualities and their classification, that is, to which of the different 

 bottom-species each single specimen is to be referred. As the percentage of carbonate of lime must 

 necessarily be known to be able to decide the last question, and as, moreover, it is closely connected 

 with the colotir and the other qualities, I have been obliged to include this examination in the present 

 section. In the following table all the details belonging hither, have been enumerated; the signification 

 given by me to the particular expressions used, is explained afterwards.
