donous bushes or trees, bespeaking still more empha- 

 tically a continental or island origin. Finally, in the 

 uppermost part of the same core Phleger and his co- 

 workers found a "displaced fauna" consisting of 

 benthonic shallow-water foram shells which apparently 

 had lived in depths of 100 to 200 meters. 



One is at a loss to explain how these products of a 

 coastal shelf and supramarine vegetation could have 

 been carried to the position of the find at lat. 7° 29' N., 

 long. 45° V W. The nearest part of the coast of South 

 America is the Amazon Estuary situated at a distance 

 of about 500 nautical miles. F. Locher, a collaborator 

 of Correns who has studied these and other "Albatross" 

 cores from the equatorial Atlantic, has failed to find 

 any close resemblance between the heavy mineral com- 

 ponents in the deep-sea sand at this locality and the 

 heavy minerals in cores taken by the "Meteor" near 

 the Amazon Estuary.- Moreover, Locher has found 

 similar (although not so thick) sand horizons occurring 

 in cores taken from a stretch of the equatorial Atlantic 

 bottom running northwest to southeast from the posi- 

 tion given above. Altogether, the sand in these cores 

 was neither so profuse nor so coarse grained as in the 

 first, most northwesterly, core mentioned. In the event 

 that a large island harboring vegetation and with a 

 fairly extensive shelf crowned the Mid-Atlantic Ridge 

 north northwest of St. Paul's Rocks and became sub- 

 merged during a catastrophe of seismic-volcanic char- 

 acter a few hundred thousand years ago, material like
