IS'o. 115.— Eridan-i.— Closely n.f. v' (Lacaille) Eridani (52 El.) 

 6 m. Harding. Not in Lacailleh Catalogue. There was no star of 6tli 

 magnitude in this position in Feb., 1876, but with 3-inch refractor I 

 found, close to the place, a small star about 10|- or 11 m., which may 

 possibly be variable. Position given only approximate. 



ISTo. 116. 53 ERiDAifi. — IS'ot given by Ulugh Beigh, Tycho Erahe, 

 or Hevelius ; Sir W. Hersehel gives 53,8; 3J and 3 m. Lalande 

 (8776-7); 4 m. Harding; 4 m. Heis ; 4-1 Gould; 4 m. Eranks, Dec. 7, 

 1877; 4 m. Cape Cataloyiie {187S- 63). I found it of a reddish tint, 

 and a little less than /x Leporis, Eeb. 17, 1876. 3-89 H.P. 



ISTo. 117. 54 ERiDAisri.— 4i and 31 m. Lalande (8860-1); 5 Heis' 

 6-5 Behrmann; the Cordoba estimates vary from 4'4 to 5*2; 5 m. in 

 Cape Catalogue (1878-63). 4-48 H.P. 



'No. 118. — Eeidai^i. — 6 m. Harding (underlined) ; not in Lalandeh 

 Catalogue. It is situated 20' due north of the star Lalande 8951. 

 Position only approximate. In Eeb., 1876, I found this star only 9 m. 

 and a little fainter than another star a few minutes to the north of it. 



No. 119. TT^ Oeionis.— (tt^ Gould) (= 1 El.) ; 5 and 4im. Lalande; 

 4 m. Argelander ; 4-3 Heis ; 4 m. Eranks, Dec. 7, 1877 ; 3-62 Pritchard 

 (1881-974 and 1883-040). It was rated 3-4 by Gould at Albany, 3-1 

 at Cordoba, 1871, but afterwards fainter. Dr. Gould thinks it probably 

 varies by more than a unit in a long period ( JJ. A., p. 325). 



March 18, 1876, I found tt^ about \ mag. brighter than 77^ (^l-)- 

 March 8, 1883, tt about 3-7 — more than ^ a mag. brighter than tt^. 



No. 120. B. 85 Tatjri. — 9 m. Bessel ; 8-1 Argelander. Birmingham's 

 estimates of magnitude, 1872-1876, vary from 7 to 10 ; 10 m. Webb, 

 1874, Jan. 12, 9 m. March 7. I found it below 8 m., 26 Nov. 1878. 



No. 121. 60 EridajS-i. — 5^ Lalande; 6m. Heis. It is a red star, 

 and the Cordoba estimates vary from 4-8 to 5-8. 5-19 H.P. 



In Nov., 1876, I found 60 a little brighter than 58 Eridani (5-7 m. 

 Gould). 



No. 122. Lalai^de 9167 Eridani (7|- m.) — This star was missed by 

 Bond in 1849 {Mon. Notices R.A.S.Noy., 1849). It is 8 m. in Harding's 

 Atlas. About 11' nearly due south of it is Lacaille, 161 3 (7 m.), which is 

 not given by Harding or Lalande. There may possibly be some error in 

 the declination observed by either Lacaille or Lalande. 



No. 123. 0^ Orionis. — No. 87 of Birmingham'' s Catalogue; 5 m. 

 Lalande and Harding ; 5 Piazzi ; 6 Bessel ; 6 Heis; 6 m. Eranks (=6 

 Orionis), Dec. 7, 1877. 



No. 124. 5 Orionis.— 51 m. Lalande (9183); 6m. Bessel; 6-5 

 Piazzi; 6m. Heis; not in Argelander's tfranometria ; 6m. Eranks^
