Abstract
The recently proposed ''correspondence principle'' of Horowitz and Pol chinski provides a concrete means to relate (among others) black holes with electric Neveu-Schwarz-Neveu-Schwarz charges to fundamental stri ngs and correctly match their entropies. We further test this correspo ndence by examining the greybody factors in the absorption rates of ne utral, minimally coupled scalars by a near extremal black hole. Perhap s surprisingly, the results disagree in general with the absorption by weakly coupled strings. Though this does not disprove the corresponde nce, it indicates that it might not be simple in this region of the bl ack hole parameter space.
