to the similar plateau basalt areas of the Deccan, Thulean, Ore- 
gonian, Palisadan, and Siberian regions. 
In this preliminary sketch of the relation of various comagmatic 
regions to the main features of the Atlantic area, expecially as regards 
the Wegener hypothesis, it seems to be scarcely necessary to discuss 
the relations in other parts of the earth (Lemuria, for example) men- 
tioned by Wegerer in the course of his discussions. Mention may 
be made, however, of a minor point in Wegener’s argument.’ This is 
that he believes that the Pacific voleanic islands are ‘‘fragments of the 
lithosphere and that they are in so many cases so completely covered 
with lava that the lithospheric core is not visible.’’ Were this true 
the upper side of the basal fragment of the lithosphere should be not 
far below or at the surface of the ocean and we would expect to find, as 
we do at many other volcanoes, fragments of granite, gneiss, or other 
basement rocks as inclusions in the lavas. 
In the course of a recent study of the lavas of the Hawaiian islands 
a very large number of specimens have been examined but not a single 
inclusion of such igneous or metamorphic rocks, or of limestones or 
sandstones, has been found. The only xenoliths that the Hawaiian 
lavas contain are of dunite, lherzolite, pyroxenite, or gabbro—all 
evidently cognate inclusions (enclaves homoeogénes of Lacroix) 
produced by magmatic segregation in the basalts. Lacroix" has 
recently shown that the supposed granite of Bora-Bora in the Society 
Islands is a medium-grained olivine gabbro, either intrusive into the 
abundant basalts of the island or (as seems to me to be more probable) 
a cognate inclusion like those of the Hawaiian Islands. A somewhat 
extensive search through the literature on the petrography of the 
voleanic islands of the Pacific has not revealed any example of inclu- 
sions of granitic or other continental rocks. Wegener’s suggestion may 
therefore be regarded as unsupported by evidence.
