In conclusion, Iam deeply sensible of presuming to differ 
from many former writers of much greater knowledge than 
myself, but it is the privilege of science—and without it the 
_ number of new discoveries would be limited—not to blindly 
accept authority when it appears to be at variance with your 
_ own observations; and I would respectfully suggest to the 
Director of the Geological Survey that he should send one of 
his staff, wholly unconnected with the controversy, to carefully 
work out the beds, keeping an accurate record of the fossils 
found in each, which would set at rest the true position of these 
much disputed beds.
