On the whole, the same rise of temperature with 

 irregular variations, as seen in April, is continued. 



Salinities. 



The samples were all surface water with one or two 

 exceptions, since there appeared to be practically no 

 difference between surface and deep water at this depth 

 (20 faths.).

The salinities show very little fluctuation throughout 

 the two months. The small variations can scarcely be 

 correlated with weather conditions at Port Erin, except
