AN interesting halo round the sun was seen a few miles from here, on Dartmoor, from 7.30 p.m. to sunset on June 7. The halo consisted of a double circle, the inner one having an angular radius of about fifteen to twenty degrees, with concentrations of light at the top and at the right extremity—the bottom of the ring was below the horizon, and the left extremity hidden by clouds—and a concentrated ray from the sun to the top of the circle. The outer circle was double the diameter of the inner one, and much fainter. A similar halo round the moon (with the exception of the outer circle) was observed the same evening.
