The spectrum of elementary string states in type II string theory contains ultrashort multiplets that are marginally stable. {ital U}-duality transformation converts these states into bound states at the threshold of {ital p}-branes carrying Ramond-Ramond charges, and wrapped around {ital p}-cycles of a torus. We propose a test for the existence of these marginally stable bound states. Using the recent results of Polchinski and Witten, we argue that the spectrum of the bound states of {ital p}-branes is in agreement with the prediction of {ital U} duality. {copyright} {ital 1996 The American Physical Society.}
