the latter at the other Stations being entirely masked 

 by inflowing fresh water. Even Station VII, which is 

 nearest the Welsh coast, is liable to be affected by the 

 fresh coastal water, which probably accounts for the 

 somewhat irregular results at this Station. 



On looking through Table I one is struck by the 

 remarkable similarity in the salinities at any particular 

 Station and at corresponding periods of the year during 

 the years 1907, 1908 and 1911. Stations V and VI are 

 particularly striking in this respect, while the results for 

 Station VII are somewhat less regular. 



Similarly, the very close agreement of the salinities 

 throughout the two years, 1909 and 1910, is worthy of 

 particular note. 



It certainly looks as though years when the salinities 

 are low during the winter months at these three hydro- 

 graphic stations (and probably at others as well), are 

 years when the following summer months are unusually 

 gloomy and wet. During such years it would appear 

 that the Gulf Stream Drift is so feeble that the maximum 

 salinity is not reached before May, and is then a good 

 deal lower than usual. In other years the maximum 

 salinity occurs several months earlier, and is a good deal 

 more pronounced. 



In 1911, which was, of course, a quite abnormal year, 

 the maximum seems to have been reached at the very 

 beginning of the year or even at the end of December, 

 1910. I believe that this is quite unusual in our area, 

 and am inclined to associate it with the brilliant 

 character of the summer of 1911. 



Unfortunately, we have no data for December 1906, 

 190T, 1908 and 1909, but from the general character of 

 the salinities during those years I believe that the 

 salinities during December were slightly lower than those
