place, the absence of any overlying till. An overlying till of insignifi- 
cant thickness has been observed, as it appears, by only one geologist 
(Tullberg) in one single locality, and the authors say that this observa- 
tion was a misinterpretation of the facts. The supposed later till is 
described as a stony sand, perhaps somewhat “kneaded” into the 
underlying clay. It is not of morainic nature. It would, at all events, 
be unlikely that morainic material should have been left by an ice- 
sheet in one single locality, while nearly all of the clay in the vicinity 
remained uncovered and undisturbed. ‘The prevalence of arctic con- 
ditions at the time of the making of the clay is indicated by the pres- 
ence throughout the deposit of gadus polaris, SABINE, and the marine 
origin of the clay is evident from the presence of the same fossil and 
also by the presence of small fragments of marine coscinodiscus, of 
fragmentary spicules of spongza, and of no less than 33 species of 
foraminifera. Attention is called to the fact that the Lomma clay in 
many respects resembles the glacial clay of central Sweden, and the 
authors regard it as equivalent to the laminated clays near Sandham- 
maren and of several other places on the southeast coast of southern 
Sweden. 
The foraminifera of the Lomma clay have been made an object of 
special investigation by Victor Madsen. From the comparative scarcity 
of these remains in this clay (such remains being found in abundance 
in shallow marine deposits in Scandinavia), from the disintegrated 
condition in which they are often found, and from the total absence of 
the largest species, he concludes that the tests were transported to 
their present place, by currents, from their real habitat, and that the 
clay was probably laid down on the bottom of a bay somewhat shut off 
from communication with the open sea. ‘The identified forms are 
referred, with some hesitation, to a late stage in the glacial age, or, in 
the words of the author, “‘they bear a late glacial stamp.”

The spirit and method of this discussion, which is essentially a 
restatement of familiar arguments against the divisibility of the glacial 
period, are shown by the opening sentence ‘‘Even in the domain of
