161 a. Y Capeicoeni. — A fine ruby star," observed as 6|-m. by 
Sir John Herschel at the Cape. It is Lalande, 38839 (= AOeg 20363), 
ind Eirmingham, 545 (= Schj. 238). It was found to be variable by 
3ecchi, in 1869; and in July, 1875, and JN'ovember, 1876, I found it 
mly 8Jm. in the Punjab, and called attention to its probable varia- 
jility {Southern Stellar Objects, p. 107). The variability has lately 
oeen confirmed by Safarik. {Olservatory, November, 1885.)

1886. August 17 ± — — Knott. 
164. H Cephei. — Observations in 1885 by J. Eaxendell, junior, 
how only a fluctuation of light of about two-tenths of a magnitude. 
[Olservatory, April, 1886.) 
165 «. Y Cygni. — This is the red star discovered by Birmingham, 
!.881, May 22, 2° 51'-7^ of a Cygni. (It is 635 of Gore's Cata- 
logue of Suspected Variables.) Herr Lindemann observed maxima, 1882, 
iugust 31 (mag. 6*8); and 1883, August 5 (mag. 7-3). Schmidt, 
lowever, found a maximum on July 17, 1882 (mag. below 7); and 
kfarik, on June 17, 1882. A maximum was observed by Eaxendell, 
|!.885, December 30 (mag. 9*5) ; and a minimum, 1885, May 31 (mag. 
.3*2); at this minimum the star remained "unchanged for a period 
tf four months." {Observatory, April, 1886.) Espin gives period 
: 440^ ±, with mean epoch, 1886, January 1. 
166. S Delphini. (Eaxendell's E Delphini.) — The maximum and 
ninimum given were observed by Eaxendell : maximum, 9*0 mag. ; 
ainimum, 11*1 mag. Eaxendell, anothermin., 1886, December 12. 
166 a. — Cygni. (Lalande 40083). — A short period variable, dis- 
iovered by Chandler in I^fovember, 1886. He gives the following 
elements : — 
1886, October 13^4^20- Cambridge (U. S. A.) M. T. + 15<^ 14^24- E. 
The increase of light occupies about four days ; the decrease, ten 
lays, with a halt in the latter about midway of its course." (Gould's 
dst. Journal, l^o. 148.)
