Query: Microcanonical Quantum Statistics of Schwarzschild Black Holes   It is shown that a quantized Schwarzschild black hole, if described by a
square root energy spectrum with exponential multiplicity, can be treated as a
microcanonical ensemble without problem leading to the expected thermodynamical
properties.
