Abstract
Pair production of Reissner-Nordstrom black holes in a magnetic field can be described by a Euclidean instanton. It is shown that the instan ton amplitude contains an explicit factor of e(A/4), where A is the ar ea of the event horizon. This is consistent with the hypothesis that e (A/4) measures the number of black hole states.
