No. 5, TT Puppis. — Stanley "Williams says {Astronomical Register, 
'ctober, 1886):— "This beautifully coloured star is IS'o. 171 of 
iirmingham's Catalogue of Red Stars, having been noted red by 
■ ichmidt. Herschel, with the 20 ft. reflector, only called it yellow ; 
ad in the U.A. it is only marked with a single r. Gore, in 1875, 
mnd the large star a beautiful orange, and in the end of 1885 and 
mmencement of 1886 it was certainly one of the finest orange stars 
I the heavens. It would seem from this that there is a strong 
probability of variation in colour. It has also been suspected to vary 
L brightness, and my observations made on about thirty nights in 
385-6 confirm this, the determinations varying from 2'3 to 3-3. 
his star may, therefore, now be placed on the list of known variable 
»ars." 
N'o. 11. — Sextantis. — This star lies a little s. f. DM + 7^, 2181 
;-3 m.), Gould, and about 11' south of Lalande, 19207 (8^). It is not

Wo. 12^55. Lalande, 2091 8, Hyde^. — 6|- Lalande ; 6 m. Argelander ; 
m. Tacchini (1868-309) ; estimated 7*3 at Cordoba, 1871, July 6, and 
m. in May, 1877, but found only 9 m. by Chandler, 1888, April, 
his star evidently requires careful observation. Pr. Gould calls it 
very red." ( Uranometria Argentina, pp. 303, 304). It is Birming- 
im 248, and is No. 329 of my Catalogue of Suspected Varialle Stars. 
i'< is one of the reddest stars in the heavens.
