New York, June 13th, [1946] Dear Dr. Federn: Your argument concerning Osorkon II erasing the cartouches of Ramses II sounds as a real argument. But it stands alone against hundreds of arguments that I presented in my Ages In Chaos. Still it must be eliminated. What makes it certain that Osorkon II belongs to the Libyan (XXII) Dynasty? I suspect that he might have lived later. In your last letter there were so many reference that it will take time before I shall be able to go through all of them. Thank you so much, In about two weeks I halt have rewritten the third file of my cosmology, on the condition that I shall work on it. Cordially yours, Immanuel Velikovsky
