      Dr. Murphy has made an egregious amateur error. His "constant
    curvature spaces" already PRESUME the existence of a
    "locally Euclidean metric" (i.e. that the metric reduces to the
    Euclidean metric for small differential distances...
    i.e. is "locally Euclidean").
      The fact that the title of the book he quotes from is
    _Riemannian Geometry_ certainly would tell one that, since
    the Riemannian Metric is DEFINED as a metric which reduces
    to the Euclidean (Lorentzian in 4D) Metric for dx -> 0.
      BTW one really shouldn't be so presumptuous as to tell people
    that they are wrong without knowing what one is talking about
    Dr. Murphy. It's quite rude.
