Air temperature— Dry bulb: 54° F. to 53° F. ;. 



Wet bulb : 53°-5 F. to 57° F. (the air 

 was saturated during part of the 

 18th) ; 

 Sea temperature at surface — 1CP-6 C. to 12°-2 C. ; 

 Specific gravity of sea at surface — 1026 to 1026*3; 

 Transparency of sea — The greatest depth at which a 

 white enamelled 2ft. disc could be observed 

 was 15ft. 



The fishes caught in 11 hauls made on the two days 

 are tabulated on the following pages.

Special attention was not directed to the invertebrates

 comis, Hippolytc rarians (a few specimens on seaweeds), 

 Buccinum, Fusus (both numerous), Cyprina, Ostrca, Mytilus
