Preface 



IN addition to more than one hundred technical and other 

 contributions, this is the third volume to be published, 

 dealing with oceanographic researches on the life of the 

 waters about Nonsuch, Bermuda. For the past six years 

 these studies have been carried on by Dr. "William Beebe 

 and his staff, Mr. John Tee- Van, Miss Gloria Hollister and 

 Miss Jocelyn Crane, of the Department of Tropical Re- 

 search of the Zoological Society. 



These expeditions have been financed chiefly by the gen- 

 erosity of Mr. Harrison Williams, the late Mr. Mortimer 

 L. Schiff, the National Geographic Society and the Trus- 

 tees of the New York Zoological Society. 



The present volume describes the various descents made 

 by Dr. Beebe and Mr. Barton in the steel ball known as the 

 Bathysphere, to an extreme depth In the ocean of over half 

 a mile.
