INTRODUCTION. 
In the summer of 1892 the Johns Hopkins University sent 
out a party of investigators to the Bahama Islands to form 
there a marine station. 
It was my good fortune to be a member of the expedition, 
and I desire to express here the obligation I owe to the Uni- 
nersity for its generosity. To Prof. W. K. Brooks I am also 
indebted for this opportunity to join the members of the Uni- 
versity in the marine work for the summer.
