DCP-LETT-2996A

From:
Charles Lyell, 1st baronet
To:
Charles Robert Darwin
Date:
24 Nov 1860
Source of text:
The University of Edinburgh Centre for Research Collections (Lyell collection Coll-203/A3/7: 40–8)
Summary:

CL has calculated that elevation and subsidence of certain formations in Sweden and Norway take place at the rate of 2 1/2 feet per century. He now proposes to estimate the age of a bed by including a conjecture that pauses occur in the oscillations in the ratio of 4 periods of stasis to one of movement. Applying this formula to Scotland, the last subsidence and re-elevation would be 590,000 years and the age of the beds with human implements would be 20,000 years.
