been said to show that this new branch of Paleonto- 
logy may lead to interesting results. The fact that 
they are, in some manner, peculiar to this region, 
seems to call upon our Society to obtain a sufficient 
number of specimens to exhibit to scientific men’ a 
fair representation of the condition of Ichnology in 
this quarter of our country; and we have therefore 
great reason to congratulate ourselves, that, through 
the vigilance and spirit of our members, the Society 
has the expectation of obtaining a rich collection 
of ichnological specimens.
