whose supervision the operations were performed. Now Fowler 
remarks for at least one of the hauls, stat. 13e, that the net is 
suspected of having closed nearer to the surface than the depth 
recorded, 270 fths. Thus all the richer captures of M. glaciale 
really are from moderate depths and there remain only some 
single specimens from the deeper hauls. Even if we presume

that the nets have closed at the depths recorded (which may 
admit of doubt) these few records may be explained, I think, by 
the special hydrographical conditions of this area. The inflowing 
Atlantic water (Gulf Stream) meets here with water of Arctic 
origin (The East-Iceland current) and is moreover as a surface- 
current in touch with the cold water of the Polar deep. Hence 
it is probable that within this area some plankton-elements — 
to which also young-fish must be reckoned — may be carried
