50 TJie Amcrica7i Geologist. January, loou 
by professor Crosby as the proljable structure. This would 
be a somewhat constricted anticline for the beds in the south- 
ern portion are nearly ver^tical, while those at the northern 
limit dip. according to professor Crosby, southward at a high 
angle. 
The beds bearing the trilobites occur in the extreme south- 
ern portion of the belt. This would bring them, accepting 
professor Crosby's view, very near to the top of the series. 
The limestone beds, bearing the pteropods, lie to the north, 
and are, therefore, to be regarded as stratigraphically below 
the trilobite horizon. 
The fauna of this locality seems more closely related to 
the Conception bay. New Foundland, fauna than to that of 
any other known region. The two most abundant forms, 
Olenellus (H.), broggeri, and Agraulus (S.), strenuus, are 
characteristic of the New Foundland locality. The greater 
number of the other forms are found in both places. Olenellus 
(Mesonacis) asaphoides is not reported, so far as is known, 
from Conception bay. 
Note. — I wish to acknowledge my indebtedness to Mr. A. 
W. Grabau, who has worked with me in collecting and iden- 
tifying the fossils, and to Mr. T. G. Watson, who assumed 
the expense of opening up the ledge. I am under obligation 
also to Mr. Richard Ash, who has allowed us to blast upon 
liis property. 
REVIEW OF RECENT GEOLOGICAL 
LITERATURE. 
The diii/iinia/ theory of the earth., or Nature's system of constriiet- 
ing a stratified physical world. William Andrews, New York, 1899, 
Published by Myra Andrews and Ernest G. Stevens, Octavo, pp. 551, 
S3. 50. 
The author of this volume, which is well printed and carefully edited, 
seems to have assumed a remarkable hypothesis without any evidence, 
and to have spent much time in rambling through much scientific litera- 
ture in search of data on which it could be established. He was evi- 
dently an uncultured and uneducated man, with a vigorous intellect 
which, still, was incapable of classifying and digesting facts so as to 
bring them to bear on the theorv which he aimed to demonstrate.
