Abstract

THE TRANSIT OF MERCURY ON MAY 8.—Fine weather favoured the observation of this phenomenon at Greenwich, Ipswich, and several other stations. Egress took place i J hours after sunrise; owing to the low altitude the limbs were somewhat tremulous, which made it difficult to time the contacts with accuracy, but they were concluded to have taken place some seconds earlier than the predicted times, which were, for Greenwich, 5h 36 13s A.M. for internal contact, and 5h 39 12s for external contact. Mr. E. H. Collinson, at Ipswich, made them 5h 36 5s and 5h 38 30”. He noticed a “black drop “before internal contact, and also saw a somewhat lighter ring surrounding the planet when wholly on the sun's disc. This effect has been noted before, and is probably optical.
