A New Variable Star in Camelopardus. A red star was detected 1887 Febr. 28, and on March I and 3 it was estimated 8m2 and 8?o, from the com- parison stars : DM. +68?401 Mag. 8.4 and DM. +68?400 Mag. 9.1 while the red star was dentified as : DM. +68?398 a = sh 2 ~ ~ 2 2 ~ 6 = +68"42:5 Mag. 9.3. It was observed as 8?0, 1887 Nov. 14. On the night of Febr. 16 1891 it was found to be only 9?1, and on Febr. 19 9?2. It was observed by Mr. Knott 1891 Febr. 26 as 9?7 or IO?~. The star is Es.- Birm. No. 146. The star was believed to be IV type on one night, but on another, neither III nor IV, one very broad band and a suspicion of a bright line being noted. 0.5857 Tow Law, Darlington, 1891 Febr. 28. 0.4885 22 23 24 6 16 4 32 2 50 52 7 50 44 49 24 48 6 46 5' 45 38 44 26 43 I7 42 10 41 5 9 40 3 April I 3 4 5 6 7 8 9 2 10 Ephemeride fur den Cometen 1890 11.
