The spectacular displays of the Andromedid meteors in 1872 and 1885 have never been repeated and they have often been listed as a "lost stream." Precise photographic measurements with the Harvard Super-Schmidt cameras over the period 1952-56 have disclosed 23 meteors that follow the orbit of Biela's comet and represent the remnants of the swarm. The individual orbits show evidence of perturbations caused by the earth and Jupiter. It is deduced that the orbit of the Andromedid swarm now passes 0.03 a.u. above the earth's orbit. The Andromedid meteors described here have been perturbed in the plane of the comet orbit, a process similar to the dispersion observed in the sunward tail of the comet Arend-Roland.
