♦Memoranda discussing the scientific equipment and programs of the Galilee and Carnegie based on 

 personal experiences of staff-members, and incorporating suggestions for improvements in instruments, 

 observational procedures, ship's equipment, and comments on any other matters on which constructive 

 suggestions might be of benefit to investigators planning future ocean work. These were prepared in 1930 

 and given limited circulation at that time. In the present volume the papers are presented essentially as 

 written in 1930, only a few deletions having l)een made of suggestions and comments no longer applicable, 

 and a few statements corrected on the basis of more up-to-date information. The papers represent an 

 important series of reports on practices and procedures on board the Carnegie , particularly because the 

 seventh and last cruise was the only one on which a very diversified program, including magnetic, electric, 

 meteorological, and oceanographlc measurements, was carried through.
