The Prominences. 
The photograjjlis show that at the time of the eclipse there were several promi¬ 
nences visible, the shorter exposure showing about twenty in all, most of them being 
small, and the whole of them being in the southern hemisphere. 
The two most conspicuous in the south-west quadrant are shown in Professor 
Langley’s photograph taken at Wadesboro, and a copy of both is given here for 
comparison (Plate 4). The interval between the taking of the two photographs 
would Ije about 2 hours, the time occupied by the moon’s shadow in crossing the 
Atlantic. In this interval the prominences have altered somewhat; the dark central 
rift of the more northerly one has disappeared, and so has the spiky appearance of 
the rays. In this photograph it has become a broad flame like a prairie ni’e, the tq3s 
of the flame for the most 23art pointing towards the north. 
This prominence a2323ears from the report on the prismatic cameras to be comjDosed 
chiefly of calcium, but it also shows on the hydrogen, helium, titanium, strontium, 
4687 (unknown), asterium and magnesium (h) rings. 
The other large prominence, somewhat to the south of the last, is shai^ed like a 
fleur-de-lys. In Professor Langley’s photograj^h the three flames are nearly straight; 
ljut on this plate the two outside ones have bent over inwards tovmrds the central 
flame, forming tv/o loops. 
This 2 )rominence is well deflned in the calcium, less well in the hydrogen, and 
feebly in the helium rings. 
The Corona. 
The j^lates show none of the coronal luys, the longest being only about half the 
sun’s diameter in extent. The jDolar rifts are somewhat shaiq)ly sej^arated from the 
equatorial extensions, and are about 5 minutes of arc in height. The j^rominences 
are not situated in any relation to the rays, and ajDj^ear indiscriminately under rays 
and rifts. 
A comiDarison which has been made with Professor Langley’s photograph shows 
that no change in the corona took ^jlace in the interval between the taking of the 
plates. • 
This is illustrated Ijy the two photograi^hs rej^roduced in Plate 5, shovdng the north 
2 )olar rays in both cases.
