Various one-loop corrections to the four-graviton interaction in type-II superstring theory and heterotic string theory are sorted out and some of them explicitly calculated. In particular, the leading correction for ..cap alpha..'..-->..0 from the heterotic amplitude is obtained. Also the nonleading nonanalytic corrections are discussed and their correspondence to the one-loop supergravity diagrams is used for their classification.
