No. 101. P III 213 Tauei.— A triple star, 7-5,8, 12: 128-1, 

 240° : 7-2" , 60" ; Webb says, " 12 var ? South missed it, 1823. 2 rated 

 it differently in different years." Chambers remarks, "■ There seem 

 grounds for supposing C to be variable." 



ISTo. 102. Lalakde 7737 Eeidani. — 7 m. Lalande ; 6-7 Heis ; not in 

 Argelander's Uranometria. Found only 7-6 m. at Cordoba. It is not 

 in the Cape Cataloyue (1880). 



IS'o. 103. Lalande 7710 Peksei. — 6i- Lalande; 5 Harding ; 6 m. 

 Heis. 17 March, 1876, I found it about e^-m. ; 3 Nov., 1878, and 12 

 Nov. 1882, about 6^m. — less than 56 Persei ; 3 Oct., 1883, I estimated 

 it 6-2 m. 



No. 104. 47 Tatjei. — 6i m. Lalande (7888) ; 5 m. Argelander and 

 Heis ; 6 m. Pranks (= 46 Tauri), Dec. 7, 1877, and = P.I.V. 19. It is 

 5-2 m. in the Uranometria Argentina; and marked ''red." 4-97 and 

 4-6 H.P. 



Sept. 27, 1883, I found 47 three steps brighter than 46, and two 

 steps brighter than 30 Tauri, but considerably less than /x (or 

 about 5-3 m.). 



No. 105. 48 Tauei.— 6 and 7 m. Lalande (7926-7); 6 Heis. In- 

 cluded by Schonfeld in his provisional list. He says (quoting Schmidt), 

 "1872, Sept. 3; kaum 7 m., mit fi'eiem Auge keine Spur, langsam 

 zunehmend. UN und Heis 6 m." A N 80, 1912, 1920. 6-39 H.P. 

 March 21, 1878, 48 about 7-3m.— 1 mag. less than 58 Tauri (6-7 



Heis). 

 Oct. 17, 1878, 48 considerably less than 58, but slightly brighter 

 than a star about 1^ n of it ; 3 March, 1883, 48 about 7 m. ; 

 April 2, 1883, 7 m. 



No. 106. 121 Heis Peesei. — Not in Lalande' s Cataloyue; 7 m. 

 Harding ; 6 m. Heis. Not in Argelander's Uranometria. Suspected 

 by Pierce {Harvard Colleye Annals, vol. ix.) to be variable. He says, 

 " The absence of this star from the Uranometria, and the great 

 difference between the magnitude assigned by Heis and me (5-8) and 

 that of the Burchmustermiy (7-7), certainly creates a suspicion of varia- 

 biHty." 7-54 H.P. 



I have observed the star as follows : — 

 Nov. 14, 1878, about 8 m. — equal to or very slightly brighter 

 than a small star closely s.f. 12 Nov., 1882, equal to or very 

 slightly brighter than the small star s.f. 



No. 107. U Tatjei. — Included by Schonfeld in his provisional list. 



No. 108. 839 H Taitei. — A small nebula discovered by Hind, Oct. 

 11, 1852, with a 10th magnitude star nearly touching it. This star 

 has since proved to be variable, and is now known as T Tauri (No. 22
