about 6 mag. The star is not in the Durchmusterung or any other 
Catalogue. On December 16, Dr. Copeland found its spectrum a 
beautiful banded one of the 3rd type, 7 dark bands being readily 
distinguished with the prism," and suspected the existence of bright 
lines. M. Wolf, however, found that the presence of bright lines was 
not confirmed when higher dispersive power was used. He considers 
that the spectrum was simply that of the well-known third type, viz. : 
a continuous spectrum crossed by bands, bounded by dark and sharp 
edges towards the violet, and shading away towards the red. He 
partially resolved the dark bands into lines. Dr. Copeland identified 
three lines in the spectrum with the edges of three bands visible in 
cometary spectra, and the spectrum of coal gas, but these views were 
disputed by Mr. Maunder. The star slowly faded, and at the begin- 
ning of July, 1886, was found by Fr. Schwab below the 12*^ magni- 
tude. It afterwards increased again, and rose to another maximum 
in December, 1886. Observations by Sawyer show a maximum of 
6-6 m. on December 13, 1886. Espin finds that the bright bands of 
the spectrum are brighter as the star is on the increase, and fainter as 
it decreases. He finds a companion 10'5, 110°, 30". 
]S"o. 38. 7] Geminoeum. — Sawyer found its light nearly constant 
from November 20, 1884, to February 3, 1885. {A.N, 2660). In 
1882 Schmidt found that the increase of light was much quicker than 
the decrease, and from his observations in 1883 he found — from the 
maxima a period of 151 days, and from the minima 135 days. 
i^o. 38<?. V MoNOCEEOTis. — From observations, 1884-1885, Sawyer 
found that The decrease of light appeared somewhat more rapid 
than the increase." {A. JST. 2660.) 
j^o. 41. S (15) MoNOCEEOTis. — From observations, 1884-1885, 
Sawyer found a variation of half a magnitude. It is a double star, 
^ 950. 
1^0. 44. E Geminoeum. — Knott found it rising to a maximum, 
1885, May 11 (mag. 7*3). It is Lalande, 13739. 
ITo. 46. L2 Puppis. — Maximum observed by Stanley Williams, 
mag. 3*55. He finds a mean period of 136-05 days with epoch 
maximum = 1878, March 16-0. {Observatory, September, 1886.)
