The gravitational lens phenomenon is shown to be not uncommon. A search is now underway to find a larger number of examples, using the VLA to search for candidates, following up with optical observations to establish equality of redshifts in the images. Most of the present lensing examples exhibit anomalous behavior that is most easily understood as evidence for large quantities of intervening non-luminous matter.
