We find that a simple scaling relation, -/sub x/ = deltaeta/R, is consistent with data on multiparticle production from 30 -- 400 GeV, where eta = -ln tan(theta/2) is the pseudorapidity of produced fast particles, /sub x/ is the average pseudorapidity of particles in excess of the hydrogen-target pseudorapidity distribution, and R = //sub H/ is the ratio of average multiplicity on a nuclear target to the average proton-proton multiplicity at equal energy. We find that the distance between the centroids of the hydrogen-target eta distribution and the excess-particle distribution deltaeta = /sub H/-/sub x/ = 1.74 +- 0.06 is independent of energy, target mass, and possibly projectile. This result implies that R increases with energy, and asymptotically is approximately proportional to ..nu.., the number of collisions of the projectile.
