To C. G. Ehrenberg 23 March [1845]
Summary
Cannot doubt that Atlantic dust comes from Africa. Could Gulf Stream have brought South American organisms to African coast?
Has come to same conclusion as CGE on volcanic origin of Patagonian stone. Formation extends 550 miles.
Could CGE examine Pampas mud to see if Infusoria are freshwater or salt-water? Results would be important.
