54 A, W. Roberts.—Catalogue of Variable [March 30,- 
This star was carefully watched throughout 1891. During the - 
winter months it was uniformly 6°6 mag. On December 6 it was-: 
noted 6:1; December 19, 5°9; December 23, 5°8; and December ~ 
25, 5°7. Since then its magnitude has not altered much, although - 
there seems indications of a slight decrease. Its colour is red, and~ 
it easily seen by the naked eye at a maximum. 
This star has decreased now (March 25, 1892) about 0°4 magnitude, | 
being fainter than L. 1523 or 6°2 mag. It is equal to L. 1551.

My attention was called to this star by Mr. Finlay. It is usually — 
equal to L. 1582 or 7:0 mag. but on December 30, 1891, it was: 
equal to L. 1496 or 6°6. Since then it has decreased slightly being ~ 
now 6°%. We have probably here a region of great activity.

Dec. — 44°°27°'7 
A variable discovered at Cordova in 1871. Careful examination ~ 
of its light curve was made at Cordova from 1871 to 1878 resulting 
in a period of 185 days. Mr. Stanley Williams finds a period of | 
136:05 days. Systematic observations were made here from April, - 
1891, to the present date. A strongly marked maximum was observed 
on February 28, mag. 3°3. Comparing this maximum with one: 
observed by Dr. Gould on February 8th, 1874, we obtain a period — 
of 136°9 days. Its variation at a maximum is extremely rapid.

Dec. — 36°: 541 
No such variation as that recorded by Dr. Gould has been noticed ~ 
here. ‘There are reasons, however, for believing it to hdve changed - 
in colour. 
Mr. Stanley Williams confirms the variation of nearly 1 mag... 
found by Dr. Gould.

A star which was noticed to vary between .the limits 6°5 and 7°4-
