MOND predicts that the asymptotic gravitational potential of an isolated,bounded (baryonic) mass, M, is phi(r)=(MGa0)^{1/2}ln(r); a0 is the MONDconstant. Relativistic MOND theories predict that the lensing effects of M aredictated by phi(r) as general-relativity lensing is dictated by the Newtonianpotential. Thus, MOND predicts that the asymptotic Newtonian potential deducedfrom galaxy-galaxy gravitational lensing will have: (1) a logarithmic rdependence, and (2) a normalization (parametrized standardly as 2s^2) thatdepends only on M: s=(MGa0/4)^{1/4}. I compare these predictions with recentresults of galaxy-galaxy lensing, and find agreement on all counts. For the"blue"-lenses subsample ("spiral" galaxies) MOND reproduces the observationswell with an r'-band M/L of 1-3 solar units, and for "red" lenses ("elliptical"galaxies) with M/L of 3-6 solar units, both consistent with baryons only. Incontradistinction, Newtonian analysis requires, typically, M/L values of about130 solar units, bespeaking a mass discrepancy of a factor of about 40.Compared with the staple, rotation-curve tests, MOND is here tested in a widerpopulation of galaxies, through a different phenomenon, using relativistic testobjects, and is probed to several-times-lower accelerations--as low as a fewpercent of a0.
