Lyell argues against tracing man as far back as Miocene times. R. I. Murchison’s argument that Africa is the oldest existing land implies that Africa is the place to look for early man.

Summary

Discusses Agassiz’s misrepresentations of his views and J. D. Dana’s "wild notions".

The reception is friendlier from younger scientists in France, and many of the best men in Germany.

Summary
