ON SPECTROSCOPIC OBSERVATIONS OF THE SUN. 
November 12th. — S.E. chromosphere billowy; S.W. 200° to 220° fumy, direction W. ; 
250° to 254° very high, fumy chromosphere; 260° to 270° direction S. ; N.W. about 280° 
low and bright, direction N. ; at 290° to 300° straight up ; about 340° fumy and flamy, 
with a W. direction ; about 0° fumy tongues with a W. direction. 
November 15th. — S.E. fumy, a few spikes straight; at 95° very billowy ; about 140° 
S.W. fumy and billowy; N.W. sharp inclination to N. at 280° to 290°, and hairy at 
that part ; elsewhere fumy. 
December 9th. — Chromosphere rather spiky near 160° ; from 185° to 210° fluffy ; 
round 213° hairy hairs straight, remainder of the quadrant billowy; round 270° very 
brilliant ; D 3 is very brilliant here between 265° and 272° in the lower parts of the 
chromosphere. 
December 12th. — From 220° round by 0° to 90° light too bad for observation ; rest 
of chromosphere regular. 
December 17th. — From 58° to 90° hairs have a slight tendency towards 90°. Rest 
of chromosphere fumy, with a few tongues or billows. 
December 29th. — Chromosphere near 20° hairy, then rather level ; at 160° spiky, and 
inclined both to E. and S. ; at 200° tongues, 215° hairy, which continues to 240°. 
Prominences at '241° and 244° are like wreaths of smoke ; 315° to 360° tongues inclined 
towards W. 
December 30th. — From 90° round by 0° to 160° light too bad for observation ; 90° 
to 160° chromosphere level ; higher at 120° to 130°. 
December 31st. — 0° to 90° light not good ; high at 85° ; very faint cloud at 132°; at 
1.55 p.m. great changes going on in the group of prominences between 252° and 
265°; chromosphere generally level. 
Spots were observed on the 23rd and 29th. On the 23rd D and the Ca lines near it 
slightly thickened, and D a little distorted, C and b not affected. Absorption general 
rather than selective. On the 29th general absorption again characteristic, C, D, b 
not affected. 
It has been noted at Rugby that all the cyclones observed from the beginning of 1872 
have, with one exception, had a motion of rotation, direct when in the northern hemi- 
sphere, and indirect when in the southern, corresponding, therefore, to our terrestrial 
cyclones. 
In the Plates accompanying this paper the horizontal lines represent each one 
minute.
