52 A. W. Roberts.—Catalogue of Variable [March 30, 
CATALOGUE OF VARIABLE STARS SOUTH OF 
— 80° DECLINATION. 
By A. W. Roperts. 
[READ 30TH MARCH, 1892.] 
THE following is a list of variable stars south of —30° Dec. with 
the latest observations concerning most of them. 
The first southern variable discovered was » Argus by Burchell 
in 1811. 
In 1866 Prof. Schmidt, Athens, among other similar discoveries in 
the Northern Hemisphere found two variables, both below the 10’ 
mag. in the Southern Crown, and in 1867 Mr. Ragoonetha Chary, 
a Hindu assistant at the Madras Observatory, discovered another 
variable in Reticulum. | 
Until the year 1872 four stars only were known to be variable 
in that portion of the sky invisible to Northern observers. 
In 1872 Dr. Gould took charge of the Argentine Observatory 
at Cordova and during the next six years discovered no less than 
thirty-five variable stars, twenty-five of which lie within the zone 
dealt with in this catalogue. 
In 1891 and 1892 six short period variables and four probably 
long period variables were added to those already known. 
These new variables are Nos. 8, 5, 11, 15, 20, 24, 25, 26, 28, and 34. 
The first and also fullest observations are those made by Dr. 
Gould and his staff at Cordova. 
His results but not the detailed observations are given in the 
Uranometria Argentina. 
In 1883 Prof. Winslow Upton of Brown University, Providence, 
U.S.A., while in the Pacific on an eclipse expedition made obser- 
vations of variable stars south of — 30° Dec. Unfortunately I have 
not these observations to refer to. 
Since 1883 no regular observations of variables have been made, 
if we except the valuable and continued examination of the light 
curve of R. Carinae made at -Windsor, N.S.W., by Mr. Tebbutt. 
It was this lack of information that induced me in May last year 
to take up the subject. The instrument used in most of the deter- 
minations at Lovedale has been an ordinary opera glass and the
