##### Abstract
We explain how the field of logarithmic-exponential series constructed in L. van den Dries, A. Macintyre, and D. Marker: "Logarithmic-Exponential power series" and L. van den Dries, A. Macintyre, and D. Marker: "Logarithmic-Exponential series" embeds as an exponential field in any field of exponential-logarithmic series constructed in F.-V. Kuhlmann and S. Kuhlmann: "Explicit construction of exponential-logarithmic power series", S. Kuhlmann: "Ordered Exponential Fields" and S. Kuhlmann and S. Shelah: "κ–bounded Exponential Logarithmic Power Series Fields". On the other hand, we explain why no field of exponential-logarithmic series embeds in the field of logarithmic-exponential series. This clarifies why the two constructions are intrinsically different, in the sense that they produce non-isomorphic models of Th(Ran, exp); the elementary theory of the ordered field of real numbers, with the exponential function and restricted analytic functions.
