GrORE — On Known Variable Stars. 191 



113. E Heeciilis. — According to Schonfeld, the Elements show 

 deviations up to 15 days ; and since 1865 there seems to be a length- 

 ening of the period. 



114. Y ScoEpn. — A maximum occurred in the middle of March, 

 1879. 



115. T ScoEPn. — This is the IS'ova of 1860, discovered by Pogson, 

 May 28, in the cluster 80 Messier, while he was searching for the 

 variables E and S Seorpii, which are situated in the immediate vici- 

 nity. The star when first seen was 7 m., and bright enough to obscure 

 the nebula. On June 10 the star had nearly disappeared, and the 

 nebula a^ain shone with great brilliancy, and with a condensed centre. 

 Pogson' s observations were confirmed by Auwers and Luther. It was 

 stated by Pogson that he had examined the nebula on May 9, and 

 found nothing remarkable ; and, according to Schonfeld, on May 18 

 it presented its usual appearance in the Konigsberg Heliometer. Some 

 trace of the star seems to have been since seen by Schonfeld, who 

 says — " Mir schien nur 1869, June 1, eine unsichere Spur desselbe 

 vorhanden." 



116. E ScoEPn. — This star is near the cluster 80 Messier, and 

 seems to have been seen by Admiral Smyth, who shows several stars 

 in the field with 80 M, in a diagram {C'el. Cycle, p. 357). Schonfeld 

 says the light curve is very variable, and the star has no particular 

 colour. A maximum was observed by Schmidt (10 m.) 1876, Sep- 

 tember, 13*4. 



117. S ScoEPU. — Only 3|' distant from E Scoi-pii. The Elements, 

 according to Schonfeld, represent the observed maxima within a few 

 days. A 9*4 m. star n.f. 



118. TJ Scoeph. — Discovered by Pogson 1863, May 20, as a 9 m. 

 star ; on May 28 it had sunk below 12 m., and on June 1 was in- 

 visible during a total eclipse of the moon. The star has not again 

 been seen, although searched for by Schonfeld and "Winnecke. 



119. U HEEcrxis. — The period given is the mean of two periods 

 deduced by Schonfeld from 8 maxima, and 4 minima since 1870, but 

 shows a fault up to 20 days ; agreeing, however, with an observation 

 by Bessel, 1825, June 13. Schonfeld calls its coloui' " intensiv roth- 

 gelb." 



120. X ScoEPn. — Discovered to be variable by C. H. F. Peters, at 

 Clinton, TJ. S., from observations 1876-1880. He found the star in- 

 visible in his telescope on the following dates: — 1879, June 23 and 

 July 8, August 11 and 20; 1880, June 2, 30, and July 11, 13, 31,
