[Eead, January 28, 1884.] 



The following Catalogue of Variable Stars will be found, I tbink, to 

 include all those stars which have been certainly proved to be variable 

 in light. The periods of most of them have been determined with a 

 considerable degree of accuracy ; but in the case of several stars in- 

 cluded in the list, although their variability has been placed beyond 

 question by the accordant observations of several independent ob- 

 servers, the exact length of their periods and the nature of their light 

 curves has not as yet been accurately determined. The following 

 stars are included in the latter class, and continuous observations of 

 them by observers in different parts of the world are much to be de- 

 sired : — a Cassiopeise (No. 6) ; S Persei (No. 15) ; E, Doradus (No. 25) ; 

 E. Eridani (No. 27) ; e Auriga (No. 29) ; S (64) Eridani (No. 31) ; 

 S Auriga (No. 33) ; T Orionis (No. 36) ; E Lyncis (No. 42) ; S Puppis 

 (No. 53); T Puppis (No. 54) ; E Velorum (No.67) ; E Antli£e(No.68); 

 S Carina (No. 69) ; TJ Hydrse (No. 70) ; T Carina (No. 73) ; E Crateris 

 (No. 74) ; Y Virginis (No. 91) ; E Centauri (No. 92) ; V Coron® 

 (No. 109) ; V Herculis (No. 124) ; h' (51) Sagittarii (No. 150) ; 

 E Cephei (No. 164) ; S Capricorni (No. 165) ; 63 Cygni (No. 174) ; 

 jaCephei (No.l79); TJ Aquarii (No. 182); and U Cassiopeise (No. 190). 



Argelander's nomenclature has been followed in designating those 

 variables lately discovered, and which possessed no distinguishing 

 letter or number. In the case of Elamsteed's stars, his numbers have 

 been retained. 



The notes on the older variables are chiefly derived from Professor 

 Schonf eld's Zweiter Catalog von verdnderlichen Sternen (Mannheim, 

 1875). To these have been added later observations by other ob- 

 servers, and further information derived from various sources. 



I have added some observations of my own on some of the more 

 remarkable variables. 



The positions of the variables have been brought up to 1880'0, 

 and the Epochs of Maxima and Minima are chiefly from Schonf eld's 

 Catalogue. 



Several of the new variables were discovered at Cordoba, and the 

 particulars respecting them have been taken from Dr. Gould's JJrano- 

 metria Argentina.
