Notes 
1. The position assigned to this line, first observed by Respighi 
(a fact of which I was ignorant when the Preliminary Catalogue 
was published), rests upon two series of micrometric measure- 
ments, referring it to four neighbouring dark lines—the probable 
error is about 3th of a division of Kirchhoff’s scale. 
g. No. 6in PC. Position there given, 743? 
16 and 17. Nos. 8andg of PC. Position given as 8168 and 
827°6, by a mistake in identifying lines upon the map. 
40. I have never myself seen this line reversed. Prof. Emerson, 
however, saw it several times. It was first reported by Rev. 
S. J. Perry, in NATURE, vol. iii. p. 67. 
41. The position of this line has been independently deter- 
mined by three series of micrometric comparisons with neigh- 
bouring lines. My result agrees exactly with that of Huggins. 
72. Erroneously given in PC, as 1363°1, which line does not 
reverse, or at least was never seen reversed at Sherman. 
100. The principal line in the spectrum of the corona. The 
corresponding line in the spectrum of iron is rather feeble, and 
on several occasions when the neighbouring lines of iron (1463, 
&c.) have been greatly disturbed, this has wholly failed to sym- 
pathise. Hence I have marked the Fe witha? Watts indi- 
cates a strong line of oxygen at 5315 A. 
152 and 156. Observed only on one day, but verified by Prof, 
Emerson. 
172. Called little C by Mr. Stoney. 
179. Given by Lockyer as K 2054. Its position is a little 
uncertain ; it seems to coincide with neither of the dark lines at 
2051 and 2054, but lies between them, a little nearer to 2051. 
189. Rather a band than a line. 
222, The position of this line, which, however, like 189, is 
rather a band, was determined by two series of careful micro- 
metrical measurements.
