ISTo. 17. — LiBE^ = Lalinde 28607. — ^^"0. 476 of Catalogue of Sus- 
wcted Variables. 
IS"©. 19. Lacaille 7646 Sagittakii. — ^0. 544 of Catalogue of Sus- 
pected Variables. Found to be variable at Cordoba, but the observations 
:,re discordant, owing to the apparent variability of several of the com- 
larison stars (V.A., p. 288). 
1^0. 20. B 535 CrGNi = DM47°, 3031.— Espin observed a minimum 
bout end of April, 1886. On May 11 it was 8'9 m., and on August 
':2 it had increased to 7*7 m. 
J^o. 21. DM + 35°, 4002 Cygm, 10 m., Pickering, 1880, but 
bserved as 8*5 m., and very red, by Espin, June 26, 1886 ; but only 
•5 m. on August 29, 1886. 
No. 22. B 541 Cygni = DM + 38°, 3957.— From observations, 
885-1887, Espin finds variation from 7-2 to 8-2. It is the southern 
tar of a wide pair. 
JN'o. 24. p Caprtcorni. — Announced as variable by Borelly in 1885. 
t was rated 6 m. by Lalande, 5-6 by Heis, 5-3 at Cordoba, and 4-98 at 
[arvard. From my own observations I had previously suspected 
ariation in tt Capricorni, which lies close to p (tt is N^o. 624 of 
Catalogue of Suspected Variables). 
1^0. 25. Anon Capricorni. — I have always found this star below 
I mag. 
26. DM + 39°, 4208 Cygni.— Found by Espin, 1885, July 9, 
3 a splendid red star, mag. 7 '9, afterwards diminishing to 9-2 ; no 
eriod found. Espin found it below 8 m., 1885, August 13, Septem- 
er 7, and September 9. 
'No. 27. — Capricorni = Lalande 40866. — Announced as variable 
y Borelly in 1885. 
No. 34. DM + 57°, 2568 Cephei. — A fine orange-red star^ found 
y Espin. Yariation observed from 7-0 to 8*0, with probably a short 
eriod. 
No. 34. W PisciUM. — This star is not in Lalande' s Catalogue, or 
larding' s Atlas.
