PRESIDENTIAL ADDRESS. 11 
At Guelma favourable conditions occurred, and Mr. 
Newall made many good observations with the Cambridge 
great spectroscope; M. Tripied, Director of the Algiers 
Observatory was at this place also. The corona was 
reported very bright, not extensive, and uniformly dis- 
tributed round the sun. Red protuberances were well seen 
and also Baily’s beads, Mercury, Venus, and Regulus were 
visible ; the temperature fell during the eclipse from 91° to 
82°; shadow bands were observed, 
The Astronomer Royal of Greenwich was at Sifax, in 
Tunis, assisted by the crew of H.M.S. Suffolk; a French 
party was also there, under M. Bigourdeu: partial cloud 
interfered, and the eclipse was fairly well observed and 
photographed; nothing extraordinary was noted in the 
corona, which was of the characteristic maximum type, 
with streamers extending as much as two diameters from 
the disc, and of a “‘rosy colour.’? There was no definite 
beginning to the eclipse, the crescent never wholly dis- 
appeared, or rather it merged into a magnificent group of 
prominences spread over an are of almost 30 degrees, near 
the spot where the last of the sun’s true disc was seen. 
They must have been of immense height, and it seemed at 
least 30 seconds before they were hidden by the advancing 
moon; at the same time, gradually too, the corona 
emerged. Observers who have seen many eclipses say it 
was but a poor corona; to others it did not seem so. In 
place of the sun’s crescent an inky black disc hung in the 
sky, with a great span of rosy prominences east of its 
vertex, and at all other parts of the circumference streaks 
and streamers of pale but defined substances were set with 
the strangest irregularity, brilliant, round the edge of the 
disc, and lost to the eye some two diameters distant. 
Many observers saw arosy tint in it; others called ita 
pure silver or aluminium grey. It was most unmistakably
