We discuss four samples from the Abell (1958) catalog of clusters of galaxies. Our samples are drawn out from the Abell sample and all clusters have richness 2 and 3. With Ho = 100 km/s/Mpc and qo = +1, we examine the following volumes, defined for both galactic hemispheres:

  1. (i) RG 3: b 40° for 0° < 1 360° and b 30° for 90° < 1 240°, distance 300 < R < 750 Mpc, N = 35 clusters, 30 of which with known redshift;

  2. (ii) RG 3: b −35° for 15° < 1 232°, 150 < R < 600 Mpc, N = 15 (13);

  3. (iii) RG 2: b and 1 as (i), 60 < R < 525 Mpc, N = 110 (55);

  4. (iv) RG 2: b and 1 as (ii), 120 < R < 600 Mpc, N = 102(14).
