decided. In the N.W. quadrant the chromosphere lumpy, except near 0, where it is 
spiky. 
July 24th. — S.W. quadrant, the chromosphere covered with fluffy hairs ; in the N.E. 
quadrant it is very spiky. 
July 25th. — Only the N.E. quadrant was observed, on account of the bad light ; 0°-10°, 
spiky ; 25°-35°, spiky ; 40°-50°, lumpy, with hairs all turned to N. ; 50°-60 c , lumpy 
and low ; 80°-90°, low and bright. 
July 26th. — From 40°-90°, hairs inclined to S. ; from 30°-40°, very sharply inclined 
S., the chromosphere very hairy ; N.W. quadrant, all the hairs inclined W., and high 
near 350° ; S.E. quadrant, hairs to E., jets or splashes cover 3° at 110° ; S.W. quadrant, 
spikes inclined to S., very decidedly at 190°. 
July 28th. — Only the N.W. and N.E. quadrants were observed. In the former the 
chromosphere vras hairy, and the hairs inclined to N. slightly, except at 330°, where 
they were divergent. In the N.E. quadrant the hairs were generally straight up from 
90° to 20°, where they were slightly inclined to W. From 10° to 0° they were straight 
again. 
There was a large spot nearly in the centre of the disk ; the C, D, b lines and the 
chromium lines near b were not affected; the iron lines 5190-5, 5191-7, 5226-0, and 
5232-0 scarcely, if at all, affected. The Ca lines near D were slightly thicker. The 
spot is rather faint ; and as the general darkening of the spectrum is considerable and 
the selective absorption almost nil , a cooling only would seem to be indicated. 
July 30th. — In the S.W. quadrant from 262° to 270° the chromosphere or a long 
low prominence was 25" high; at 310° to 316° there was another prominence, a portion 
of which (about 310° to 313° or 314°) was like a coarse sponge in texture. 
July 31st. — The chromosphere as a rule is low, bright, and lumpy at from 120° to 
140°; there were indications of an inclination towards a prominence at 140°; at from 
308° to 320° there was a smoky appearance and a slight inclination to the W. 
August 7th. — The chromosphere lumpy and low from 150° to 190°; from 105° to 
115° there was a very sharp inclination to E. In the S.W. quadrant it was generally 
lumpy and any hairs straight up ; in the N.E. it inclined slightly to N., and was also 
lumpy. There was a spot close to the base of the prominence at 309°. 
August 8th. — From 90° to 70° lumpy with straight hairs ; at 48° a very low gap with 
a spike in the middle of it ; there was scarcely a trace of chromosphere in the gap for 
1° or 2°. From 70° to 30° the chromosphere was fumy or smoky, with hairs in the fume ; 
at 23° it was very low again. From 20° to 10° it was fumy, but contained well-developed 
hairs. In the N.W. quadrant it was spiky, and high at 350° to 340° ; 340° to 330° fumy ; 
at 320° it was denser, and exhibited a slight inclination of its details to N. In the S.W. 
quadrant the chromosphere was fumy with spikes, which latter were well developed 
at 182°. 
August 9th. — The chromosphere had generally a peculiar look, as though it was
