Ocean Life 
The life of the ocean is so abundant that many volumes 
would be necessary to portray it adequately. Naturally, no 
attempt at completeness has been made in a little volume 
like the present one. The author is not a biologist; his chief 
efforts have been in the physical sciences. Therefore, this 
section should be regarded as an album of pictures with 
notes, illustrating some of the life of the sea that the reader 
may someday encounter. For purposes of classification of 
animals seen, the reader must refer to authoritative treatises.
