employed was a trawl with a 30-feet beam and with 7-inch 

 meshes throughout. Trawling was continued all day 

 from 7 a.m. to 5-30 p.m., and the meteorological conditions 

 throughout were fairly constant. There was a fresh 

 breeze from N".W. during the whole da}'. The sea was 

 nearly smooth and the weather was fine. The barometer 

 varied from 30*7 to 30'5, the air temperature from 9°C. 

 to ll'G°C, and the surface temperature of the sea from 

 11;2°C. to 11 , 6°0. The results of the hauls are given in 

 the following Table.
