# Example of a space which is Hausdorff and locally Euclidean but not paracompact?

On page 330 of John G. Ratcliffe's text on hyperbolic manifolds, he defines a manifold $M$ to be a locally Euclidean Hausdorff space. By locally Euclidean, he means as usual that for each $x \in M$ there is an open neighbour $U$ of $x$ which is homeomorphic to an open subset of $\mathbb{R}^n$.

But he omits the usual paracompactness assumption. I would guess that $M$ being locally Euclidean and Hausdorff is not sufficient to imply that it is paracompact, given this problem from Lee's book.

Does anyone know of such a counterexample?

There's the long line. $\qquad$
Note that every metrizable space is paracompact and $\mathbb R^n$ with usual topology is metrizable.
