THE DEPOSITS OF THE SEA-BOTTOM. 7g 



Station 48; many Sponge spicules; very many Radiolaria, partly larger forms, partly miscro- 

 scopic ones, the latter found in an abundance of forms; a few circular and attached Diatoms. 



Station 50; a few Sponge spicules, microscopic and larger Radiolaria, and circular and attached 

 Diatoms. 



Station 54; a few Sponge spicules; some larger Radiolaria. 



Station 58; some Sponge spicules. 



Station 59; some Sponge spicules; a few Radiolaria, and circular and attached Diatoms. 



Station 63; some Sponge spicules, and circular Diatoms; a few larger and smaller Radiolaria. 



Station 64; some Sponge spicules, and circular Diatoms; one Radiol arian. 



Station 65; some Sponge spicules; one Radiolarian. 



Station 66; numerous individuals of all three groups; the Radiolaria were present in many 

 and beautiful forms. 



Station 67 ; some Sponge spicules ; a few Radiolaria, and circular Diatoms. 



Station 68; numerous Sponge spicules; very few Diatoms; some Radiolaria. 



Station 69; some Sponge spicules; many Radiolaria; a few circular, oblong, and attached 

 Diatoms. 



Station 73 ; some Radiolaria, and Sponge spicules. 



Station 74; many Sponge spicules, and Radiolaria in many forms; a few circular and attached 

 Diatoms. 



Station 75; some Sponge spicules, and Radiolaria; a few Diatoms. 



vStation 76; numerous Sponge spicules, and some Radiolaria; one circular Diatom. 



Station 77; some Sponge spicules; a few Radiolaria, and circular Diatoms. 



Station 78; the specimen containing the greatest number of siliceous organisms; an immense 

 number of Sponge spicules and Radiolaria, in the sandy ingredients far surpassing the mineral particles 

 in number; the Radiolaria otherwise of not very different forms; only a few Diatoms were found. 



Station 80; many Sponge spicules, and larger and smaller Radiolaria of several different forms; 

 one circular Diatom. 



Station 81; some Sponge spicules; a few Radiolaria; a few circular Diatoms. 



Station 83; numerous Sponge spicules, and Diatoms; a few Radiolaria. 



Station 85; some Sponge spicules, and Radiolaria; a few Diatoms. 



Station 89; some Sponge spicules, and larger Radiolaria; a few Diatoms. 



Station 90; a very great number of Sponge spicules, especially among the coarser particles 

 present in larger quantity than in any other specimen ; many larger and smaller Radiolaria of different 

 forms; many Diatoms. 



Station 91; a few Sponge spicules; very few Radiolaria, and Diatoms. 



Station 92; very few Sponge spicules, and Radiolaria. 



Station 94; some Sponge spicules, and larger Radiolaria. 



Station 98; some Sponge spicules; one Radiolarian, and one Diatom. 



Station 101 ; some Sponge spicules; a few Radiolaria, and Diatoms; the latter as well circular, 

 as oblong and attached
