') This specimen and several of the following ones (13, 31, 42, 54, 64, 77, 81, 83, 85, 89, 92, 94, 98, 115, 127, 12S and 

 129) have not, as I had before supposed, been taken with the Baillie tube, but with the dredge or the trawl. Consequently 

 the quantitative ratio between the organisms and the inorganic ingredients may have been somewhat disturbed, whereas the 

 different minerals may be taken to be present in their original mutual ratio of quantity.
