They will be referred to by the numbers given in the above table. 
Nos. 1 to 6 are calcareous muds, containing much mineral 
matter, and only a small portion of Polythalamia. The siliceous 
organisms are also comparatively few consisting of some large 
Coscinodisci, a very few Polycistine, and some Spongiolites, — 
No voleanic products were detected. ' | 
0.7 is also a fine caleareous mud showing to the naked eye 
but few Polythalamia, but rather rich in microscopic organisms, 
consisting of minute Pol ythalamia, with Polycistins, Diatoms, 
and Spongiolites. No voleanic products were detected. 
Hoping that the above will answer the purpose of a general 
Teport upon the microscopic character of these soundings, I re- 
Serve for a subsequent publication the details of the zoological 
results afforded by these highly interesting series of soundings.
