Core samples NEL 394 and 396 were subjected to bac- 

 teriological analyses by D. M. Updegraff of the Scripps 

 Institution of Oceanography. Various selective media were 

 inoculated with about 0.5 gram of sediment. The bacteria 

 present are listed in table 12. Since the samples had been 

 stored for a long period in unsterile containers before analy- 

 sis, it is not certain that the results represent the conditions 

 in the original sediment. However, every effort was onade 

 to avoid contamination by aseptically sampling the center of 

 the cores.
