The author of this paper draws the conclusion “ that in proportion as we descend 
the vast series of deposits that overspread this portion of the earth, so do we recede, 
step by step, from the circle of existing organised beings, and from the phenomena 
attendant on their structure, their habits, and their adaptations.”
