The temperature was high at the surface and fell 6° in 

 the 100 meters; the salinity decreased and the h\drogen-iun 

 concentration increased with the depth, both ^■ery slighth'. 

 Twenty-three species were taken at the surface, 39 in the 50- 



(60 per cent) were each confined to a single tow and 5 were 

 present in all three tows. Corycaeus was distributed in all 

 three tows, Farranula and Oncaea did not appear in the 50- 

 meter tow, and Oithona and Candacia were not found at the 



meter tow, and 51 in the 100-meter tow. Forty-five species surface. Lengths and \olumes of all the tows were the same.
