sibly have produced the footprints of tlieTriassic sandstones, and concludes 
by suggesting that "Darwin and his adherents will probably employ the 
new discovery as an exceedingly welcome occurrence for the justification 
of their strange views upon the transformations of animals. But in this 
they will be wrong," as, according to Professor Wagner, " the interme- 
diate steps by which the transition of some one living or extinct animal 
from one class into another was ejffected " cannot be shown. The failure 
of such proof, he says, induces us to reject their views " as fantastic 
dreams, with which the exact investigation of nature has nothing to do." 
We have laid the above brief summary before our readers, and hope 
that some expression of opinion from our numerous contributors may he 
at once evoked. The problem is one which demands the highest efforts 
both of anatomists and geologists. 
Glauconite in the Lowek Silubian Rocks. — Mr. Starry Hunt, in 
1858, noticed, in ' Silliman's Journal,' that glauconite was probably the 
colouring matter of some Silurian sandstones ; and in the Canadian Survey 
Report for 1859 he gave the analyses of this material from rocks of the 
Quebec group at Point Levis and in the Island of Orleans. In the latter 
rock there are layers which contain more than half their weight of soft, 
rounded, bright green grains, closely resembling the green sand of the 
Cretaceous period. These are a hydrous silicate of alumina and protoxide 
of iron, with about 8 per cent, of potash, and differ from glauconite of the 
secondary rocks in their larger proportion of alumina. A similar mineral 
is found in limestones of the Quebec group in Texas, and in the Potsdam 
sandstone of the Upper Mississippi. Sir Roderick Murchison has also 
recorded layers of green sand at the base of the Pleta limestone in Russia, 
and Schmidt in Esthonia and Livonia, in strata overlying the alum slates. 
Canadian Pleistocene Fossils and Climate. — Professor Dawson has 
given, in the ' Canadian Naturalist/ a complete list of the fossils of the 
drift in Maine, Canada, Labrador, etc. His conclusions are, that a far 
greater degree of cold prevailed during the Pleistocene epoch than at 
present. The causes of this difference he attributes to great changes of 
level, and in the different distribution of land and water; during the cold 
period the relative proportion of land m the Arctic regions being greater 
than at present. 
REVIEW. 
Physico-Prophetical Essays, on the Localiiy of the Eternal Inheritance, 
its Nature and Character, the Resurrection Body, and the Mutual Re- 
cognition of Glorified Saints. By Rev. W. Lister, E.G.S., Yicar of 
Bushbury, and Rural Dean. London : Longmans. 
This v. ork deserves a notice in our pages, from the large amount of 
geology in it, the discoveries of which have been carefully employed in 
determining the meaning of some of the prophecies. We believe that 
many of our readers will be much interested with these portions of the 
work . 
One great feature in Mr. Lister's volume is that it strives to fairly and 
fully prove that the Scriptures uniformly set before us a physical future, 
and that, in this respect, their authoritative declarations are in exact har- 
mony with the logical deductions and suggestions of science. 
We wish Mr. Lister's volume success, for the work, taken as a whole, is 
an original one.
