Schmidt observed a minimum of x Cygni, October 11, 1878. 



155. -q A.<xuiLM. — According to Schonfeld, the uniform period 

 given in the Catalogue does not quite suffice to represent the obser- 

 vations, which show marked deviations, amounting to over 6^ hours 

 in 1873. These variations are confirmed by Schmidt's observations. 



156. S Cygni.— The period given would, according to Schonfeld, 

 represent the observations well within the probable errors of obser- 

 vation. An 8*9 m. star n.f. 



157. E Capeicobni. — The Elements show great in'egularities, 

 sometimes amountiug to as much as 30 days. Schonfeld mentions a 

 13 m. star, nearly due-north of the variable, distance 20". 



158. S Aqttii^.' — Elements derived by Schonfeld from 10 minima, 

 observed by him since 1865. Light curve very variable. Schonfeld 

 has observed a maximum nearly midway between two minima, others 

 much nearer the following maximum, which is sometimes even re- 

 placed by a secondary minimum. A 9 m. star s.f.
