TOTAL ECLIPSE OF THE SUN, JANUARY 22, 1898.

disappeared when the slit was broiig'ht to rest on the inner corona. No measure¬ 
ments could therefore be made with the reference spectrum. When at rest on the 
inner corona in the spectrum, “ F” was seen long and bright; 1474 K (judged by iron 
lines 5323 and 5327 in reference spectrum) longer and brighter than “ F,” and 
practically filled the whole length of the slit ; four, or possibly five, bright lines very 
feeble, very close to, if not identical with, the positions of iron quartette, but not 
sufficiently bright to measure very accurately, and there was not sufficient light to 
give very good indications of the reference sjDectrum. 1 could see no enhanced iron 
lines. No carbon bands were visible. 
At 97 seconds call, Mr. Steel put slit tangentially on outer'” corona east of 
equator, when “ F ” was seen long and fairly bright; 1474 K was seen long and bright ; 
“ h” was seen very faint, with a faint continuous spectrum. No carbon bands were 
visible. No iron lines were visible. 
At 67 to 62 seconds call, I gave place to Sir Norman Lockyer, who reported he 
was unable to detect any lines in the spectrum. 
47 seconds call. —Again took my place at the spectroscope. Slit still on “ outer” 
corona, east of equator of sun, and I reported no spectrum visible. 
Afterwards, faint continuous spectrum, too feeble to make any measurements. 
32 seconds call. —Slit jjlaced tangentially on “inner” corona (east of equator of 
sun). “ F ” line long and bright; 1474 K line longer and brighter than “ F.” 
Iron lines looked for, but not visible. 
Carbon bands looked for, but not visible. 
17 seconds call. —Slit placed tangentially on “ inner” corona"^ (east of equator of 
sun). Only “ F” and 1474 K visible. 
Iron lines looked for, but none visible. 
Carbon bands looked for, but none visible. 
Call “ Totality over.” —Slit ^fiaced perpendicularly at north edge of the reappearing 
crescent of the sun. 
“ F ” long and bright. 
Magnesium (“ 6 ”) rather long and bright. 
No carbon bands visible. 
No iron lines visible. 
Call 1 minute after totality. — Working near the point of the crescent. 
“ F ” long and bright. 
Magnesium (“ h”) bright. 
1474 K rather faint. 
Carbon bands looked for, but none visible. 4871, 4890, 4956’5 (Angstrom) lines 
of iron flashed in. A bright iron line about 4956’5 of iron (Angstrom) distinctly 
bright. 
* In this case the position of the slit must have been outside that occujried at the commencement of 
totality.
