branch of the eddy, first observed by Gunther, olT Arica, was found to 

 extend as far as Iquique and south. 



In this region of interplay of water masses each with distinctive temp- 

 erature characteristic, the bathythermograph is a valuable instrument 

 particularly north of 10^ S. However, for more complete analysis and 

 more positive conclusions, BT lowerings should be supplemented with 

 salinity samplings and rigorous meteorological observations. A more 

 complete and detailed oceanographic coverage of area surveyed is another 

 desirable that must be fitted into the biological plans of any future studies.
