TRANSIT OF MERCURY.—The Government Astronomer at Sydney (Mr. C. Todd, C.M.G.) writes as follows regarding the transit of Mercury:—Good observations of the transit of Mercury were secured at the Observatory, on Sunday the 10th. At the ingress the conditions were extremely favourable, the sun's limb and the planet when projected on the sun's disk being exceedingly well and sharply defined, but at the egress the sun's limb was boiling and the planet was somewhat woolly, rendering it difficult to fix the exact time of internal contact. I observed with the 8-inch equatorial refractor, assisted by Mr. Cooke; and Mr. Sells observed with an 8-inch reflector.
