.method a modification of that of Argelander. I hope ere long to 
- obtain a wedge photometer with which, if health and leisure permit 
.me, I hope to determine the magnitudes of all stars brighter than the 
8th mag. south of — 30° Dec. 
(1) R Scurrrtorrs 
R.A. 12+25™-55* 
Dec. — 33°: 6°'8 
A variable discovered at Cordova in 1872. Its period as obtained 
- from comparing the minimum of December, 1891, with that of Novem- 
‘ber 15, 1878, is about 207°5 days. Dr. Gould found a period of 
207 days. Its red colour is very intense all through its light changes, 
which are very regular. The minimum of December 1891 was nlot 
- well marked, indeed it remained at 8°0 mag. all through December 
and January. It is now increasing in brightness and a maximum 
~ may be expected about the end of this month (March, 1892) when 
it will be quite visible to the naked eye. 
. (2) R Reticuri 
R.A. 42:32™- 138 
Dec. — 63°: 18°'0 
This star was discovered in 1867 by a Hindu observer at the Madras 
’ Observatory. Its variation, however, was leit unconfirmed. On August 
27, 1891, it was 7:2 and on August 28, 7°0 mag. It then began to 
- decrease in brightness, being invisible in the opera glass by the end 
- of October. The period assigned to it by its discoverer is nine 
- months, so that a maximum may be expected in June, 1892. 
_(8) S Retiourr (L. 1551) 
R.A. 42°32™- 22s 
Dec. — 63°: °3°'0 
The variation of this star was suspected in June. In May, 1891 
it was fainter than L. 1523 or 6°3; in June it was brighter or 6:0. 
- On December 4, 1891, it was noted equal to » Reticuli or 5°8. It is 
~now again fainter than L. 1523 or 63 mag. There can therefore 
: be little doubt as to its variation: 
- (4) R Doravus (L. 1567) 
R.A, 42-35™- 308 
7 Dec. — 62°°17°'6 
A variable star discovered at Cordova where its limits were noted 
.5°6 mag. and 6°5 mag.
