ent years; therefore only a prolonged period of observations can deter- 

 mine the average amount of salt of a certain locality, A glance at the 

 following table will give an idea of the great variations taking place. 

 Although the numbers are mere approximations, the differences are, 

 nevertheless, considerable.

 Baltic Sea, show, in general, different relations as to temperature, but 

 as they intercommunicate by way of the straits of Skagerak and the 

 Kattegat, they exercise some reciprocal influence in this point of view. 

 The condition of the Baltic with regard to climatic influences is almost 

 that of an inland sea, owing to the insignificant extent of its junctions 

 with the German. Ocean and its greater outflow. Only in the vicinity 

 of its junctions, and under certain circumstances at some distance from 

 them also, there is a considerable influence brought to bear upon the
