Euler Class of a vector field
Just take the Euler class of the orthogonal $2$plane field in $TM$, oriented with respect to $X$ by the righthand rule. I think this question is more suitable for math.stackexchange.com.

Analytic stuctures on $\mathbb R^n$ and the nilpotent ideal of supermanifolds
Michael Freedman found the first exotic $\Bbb R^4$ in 1982. As far as I know Milnor never did any work on exotic $\Bbb R^4$'s.
