nature of the bottom. On the German coasts on the west of the Baltic 

 the heavy water enters far into the fiords, whilst the undercurrent en- 

 tering through the Sound and the Great Belt is broken by the shallow 

 places known as the "Bonne-bank" and the " Oder-bank," between the 

 islands of Beizen and Bornholm, and advances with no great force after 

 it has passed this line, decreasing rapidly in saltness as it goes.farther 

 east. Between Bornholm and the Swedish coast the depth of the sea 

 is greater, and this explains the circumstance wby the heavy water can 

 here advance farther east, makiug the water in the Gulf of Finland salt- 

 ier than that of the Bay of Dantzig or that of the Baltic near Memel. 



The following figures, the result of observations made at different sta- 

 tions, will fully prove all that has been said in the above regarding the 

 saltness of the Baltic :

From these figures the following rules may be deduced : 



1. The weight and saltness of the water of the Baltic decrease from 



west to east, the entry of the heavy water into the depths of the sea 



ceasing near the island of Bugen.
