It is very probable that the unusually mild winter 
we have experienced is connected with this return of the 
Gulf Stream Drift after the period of depression which 
it suffered during 1909 and 1910. The heavy rainfall 
during the last two months of 1910 may well be due to 
the same cause for the reasons discussed in last year’s 
report and in Nature, LX XXIV, 44 (1910). 
The renewed vigour of the Gulf Stream Drift also 
gives us good reason to expect a more genial summer, 
quite different from the dismal ones of 1909 and 1910. 
_ The observations made at the different stations 
during 1910 are given in the following tables, where 
T°, Cl °/,.. S %o and o, have the usual meanings. The 
seasonal variations of the salinities can be seen at a 
glance from the concluding table.
