General Objects:— To examine— ( a ) The height of the reflecting layers of the atmosphere. ( b ) The structure of the corona. ( c ) The polarisation of the corona. ( d ) The coronium ring. ( e ) The shadow bands. ( f ) The meteorological conditions of the eclipse. Our station was near Philippeville, about 1·5 kilometres to the west-north­-west of the village of Saint Charles, on the long and broad summit of a grassy hill rising at a moderately steep slope. The position of our camp, as given by the large-scale survey map, was:— N. Lat, 36° 45' 38"·7. E. Long., 6° 51' 59"·T, or in time, 0 h. 27 m. 27·6 s. Height above sea-level, 690 feet or 210 metres. These values agreed well with independent observations made with sextant and telescope.
