Before leaving this hasty comparison between our own biological census and a few 
of the similar undertakings elsewhere, reference should be made to certain works in 
which some features of our own survey are closely paralleled. We must mention first 
of all the explorations in the Kattegat of the Danish steamer Hauchs, under the charge of 
C. G. J. Petersen. The resemblance between the Danish project and our own lies in the 
successful endeavor to correlate the distribution of various species with peculiarities 
of bottom and of water temperature, and particularly in the presentation of a number
