"Read a letter [to AC] of the 19th Instant from Mr Charles Darwin of Christs College, Cambridge stating that understanding from the Conservators that a Series of fossil Bones collected during the voyage of H: M: Surveying Vessel Beagle possesses a peculiar Interest as connected with Specimens already in the Museum of this College that it had always been his intention to present such Bones to some public collection on the condition that Casts thereof should be given to the leading Public Bodies for the sake of making them more generally useful, specifying the British Museum the Geological Society and the Universities of Cambridge and Oxford, and one set for himself: and that under such Conditions he should be most happy to present the entire series to the Museum of this College."

Asks RO whether he has any MS [of Fossil Mammalia, no. 4] ready and to see that the plates are finished.

F. J. Muñiz has offered fossil bones collected around Buenos Aires to the Royal College of Surgeons. He believes he can complete their Megatherium skeleton and provide other specimens. CD feels he should be encouraged in his work.
