TITLE: Does the paper "On the cobordism ring $\Omega_*$ and a complex analogue II" exist?
QUESTION [13 upvotes]: I've been investigating the Milnor hypersurfaces, and every reference seems to point to the paper by Milnor, "On the cobordism ring $\Omega_*$ and a complex analogue II". Despite my best efforts, I cannot seem to find it. Was this paper ever published? If not, is there a draft that is available?

REPLY [23 votes]: Here's what John Milnor writes about this, in his collected works:

The projected Part II of this paper
  was never written. In fact I am
  chagrined to discover that I have
  never published any details about some
  of the announced results which were
  intended to appear in it. I was very grateful when Thom gave me permission to reprint his 1959 Bourbaki lecture, "Travaux de Milnor sur le cobordism", which gives a better account of this work than anything which I have published. 

(page 249 of Part III of the Collected Papers of John Milnor, AMS 2007).
The paper by René Thom which Milnor mentions can be accessed here.
