ontologists generally would feel inclined to view them as different 
species, although others may classify under the head of “© Varieties.” 
On Victoria Day Mr. Schuler called my attention to the pro- 
jecting under-surface of one of the thick, massive blocks of sandstone, 
displaying a magnificent specimen of the large “‘ Arthrophycus ” in 
situ. It is in a difficult position to reach, and a dangerous one in 
addition, as loose layers are lying above it. Even when released I 
fear it may be found impossible to make it sufficiently portable to 
carry it to the stone road or railway station. The smaller specimens 
~ of the ‘‘ Arthrophycus ” are found on thin sandstone slabs, and are 
exceedingly numerous in particular parts of the abandoned quarries. 
It is not unusual to find six or seven in places after heavy rain or 
when the snow has disappeared. Mr. Schuler, a member of the 
Geological Section, extracted even more than this number from their 
position in situ this last summer. 
Having left my hammer behind at Winona, the writer, on 
Victoria Day, was compelled to restrict his fossil-hunting to the 
Niagara Shale Bryozoons, in which he was not particularly success- 
ful. This is the more to be regretted, for the reason referred to in 
a letter received from Dr. Whiteaves, the Chief Palzontologist of 
our Dominion Geological Survey. The boxes sent through the 
Canadian parcel post to Ottawa contained Bryozoons (also from our 
local chert beds), a few of which may be hitherto undescribed. 
GEOLOGICAL NOTES. 
The wonderful discovery of the Dutch Surgeon, Dubois, of the 
skull of the great ape in the river bed of Java, remarks Professor 
Herman Klaatsch, of Heidelberg University, goes far to prove that 
the ancestors of the contemporary types of apes bore a far closer 
resemblance to man than do their degenerate successors. The 
Gibbon’s arms, for example, have lengthened in answer to his needs 
as an inveterate climber of trees. A still more remarkable discovery 
has been recently made in Borneo—a race of men (dwarfs) with 
webbed feet. How is this for the pollywogs? 
In digging recently under the foundations of the Daily 
Chronicle office, in Fleet street, London, England, a well-preserved
