Hubble publishes observational evidence for a roughly linear relation between the distances of external galaxies and their radial velocities. The relation is now commonly called the Hubble-Lemaitre law.
Edwin Hubble and Milton L. Humason extend the observed velocity-distance relation to substantially more distant galaxies using new radial-velocity measurements.
