Sawyer finds tliat "the light curve exhibits a rather rapid and 
nniform increase, with a somewhat less rapid and irregular decrease. 
Its red colour render it rather a difficult object to observe." 
jSTo. 179. fx Cephei. — I have 167 observations of this star from 
llarch, 1883, to March, 1888. These show a variation of light of a 
little more than one magnitude, but with no regular period. Owing 
to its red colour, and occasionally strong scintillation, it is a rather 
difficult object to observe. The spectrum is a most perfect one of 
the third type, according to d' Arrest, the separating spaces being 
sharp, dark, and very broad. Duner finds, however, that the bands, 
although dark, are not very large. The maximum and minimum given 
in the Catalogue were observed by me.

IS'o. 184. Pegasi.— In 1883 Schmidt found a mean period of 29*7 
days. Observations by Sawyer from August 1, 1884, to January, 1885, 
showed only slight fluctuations of light of " not more than a couple of 
steps"; and from Jan. 10 to February 3, 1885; and July 15, 1885, 
to January 1, 1886, he found the light " apparently constant."

JTo. 187 19 PrsciUM. — Prom observations of this red star, 1881- 
1884, Espin finds the following provisional elements : — 
Epoch, max. = 1884, August 19 + 165"^+. 
Espin finds the star orange at maximum and orange-red at minimum. 
My observations confirm the variability. 
Duner finds a "Superbe" spectrum with large strong bands. 
Vogel's observations agree with Duner's in all essential details.
