GEOLOGICAL NOTES. 
The world itself has no limit for us. Humboldt and Herchel will carry 
us far away to the mysterious Nebule far bepond ‘‘the Sun” and even the 
Stars ; time has no more bounds than space; history stretches out behind 
us ; and geology will carry us back for millions of years before the creation 
of man, even to the origin of the material universe itself.—From Pleasures 
of Life, by Lord Lubbock. 
The series of rocks so designated are of peculiar interest 
to the geologists of Europe and the American continent, 
How far do they extend is a question frequently asked, but it 
does not admit of a satisfactory reply, since they come under 
the head of “Concealed Measures” in both directions along 
the escarpment, east and west. It was not known that the 
beds extended in the first direction even to Stony Creek, until 
quite recently. I suspected such was the case, from finding 
Chert fragments in the ravine there. The overlying soil, tim- 
ber, etc., prevented examination then. Mr. Schuler, a mem- 
ber of our section, having mentioned his intention of proceed- 
ing to the Creek lately on a collecting expedition, was re- 
quested, if possible, to clear up any doubt on the subject. On 
his return he displayed sufficient evidence in the shape of 
Sponges and Lichens, with other organisms, to show the Chert 
extended, so far at least as the place indicated. It may be 
found to thin out a little beyond, notwithstanding the immense 
numbers of graptolites discovered in these beds. The writer 
fears we have not acquired much knowledge respecting the 
young Hydrozoa. Unfortunately they are not calculated at 
an early stage to arrest attention, and even when more advanced 
they are occasionally neglected, as I noticed frequently, and 
considered hardly worth the trouble of removal. Young col- 
lectors, especially, are inclined to commit this grave mistake. 
They may not look particularly attractive in the cabinet, but 
that is a matter of minor importance. Fragments disdlaying 
cellules, radicles, etc., are also sometimes thrown aside, being
