Abstract
TELEGRAPHIC DETERMINATION OF AUSTRALIAN LONGITUDES.A “Report on the Telegraphic Determination of Australian Longitudes,” signed by Messrs. Ellery, Todd, and Russell, has recently been published by the Government of South Australia. This Report contains the final results of the operations connecting Singapore and Port Darwin, carried out in 1883 by Capt. Darwin, R.E., in concert with the Australian astronomers above mentioned. The Observatories of Melbourne, Sydney, and Adelaide were subsequently connected with Port Darwin. The preliminary results of these telegraphic longitude determinations were communicated by Mr. Todd in 1883 to Sir G. B. Airy, and published in the Observatory for October of that year. The longitude of Singapore adopted in forming the results given in the Report before us is that determined by Commander Green, U.S.A., in 1882, viz. 6h. 55m. 25.01s. East of Greenwich (for Capt. Darwin's station), assuming that of the Madras Observatory to be 5h. 20m. 59.42s. Hence the resulting longitudes are:—
