Spectra of four quasars projected within 2.8 degrees on the sky with emission redshifts near 1.9 were re-analyzed for correlations of Lyman-alpha absorbers. The group of bright quasars LB 9601, LB 9605, LB 9612, and LB 9615 probes scales on the sky of clusters and superclusters of galaxies. No significant correlation signal was detected in any of the six pairs of sight lines tested out to a velocity separation of 10,000 km/s. A pair of common absorbers was newly detected, with velocities identical to within 20 km/s. Two other common absorber pairs were also detected, with velocities identical to within 90 km/s. An apparent deficit in the number of Ly-alpha lines below the expected mean has been identified in the spectrum of LB 9612, spanning about 5600 km/s in velocity space. No hard evidence is found that intervening hydrogen clouds are correlated on the scale of superclusters of galaxies.
