down into the deeper parts. In this sinking they are somewhat stopped whcn arriving 

 to the limit of the much denser Atlantic water, the numbers being relatively high at 20 m. 

 At 40 m, where Nitzschia pungens v. atlantica abruptly oecurred in rieh quantities, we also 

 meet with a little Glenodinium tabelled as Gl. solidum, that keeps up the total number 

 of the peridinians, though the Ceratia have much decreased. Prorocentrum micans, so 

 common in the Kattegat, is nearly totally absent.

At this northernmost station of the seetion, we find the numbers of as well diatoms 

 as peridinians much increased again, thanks to the vicinity of land. This is marked 



1 Mostly D. acuta and D. acuminata. 



2 Paraiia could not be counted here, because of the sandy nature of the sample.
