For a given finite graph G and positive integer k, let r(G ; k) denote the least integer r such that if the edges of Kr , the complete graph on r vertices, are arbitrarily partitioned into k classes then some class contains a subgraph isomorphic to G . The existence of r(G ; k) follows at once from the well-known theorem of R a m s e y {8] which asserts that r(Kn ; k) < for all n and k . In this paper we investigate the behavior of r(G ; k) for large k as G ranges over various classes of graphs .
