Jan. 11.7. — Object (elongated and uebulous) observed Jan. 5 and G 

 is still at same distance as ou the Gth, so far as a lew eye-and-ear tran- 

 sits would decide. The preceding and northern ''condensation," 

 observed on the oth, now appeals as a faint star, apparently shioin<»- 

 through that wing of the slender, elongated '' nebula." 



Went on with regular search, power 400. Found curious configura- 

 tion of stars — 12 and lo mag. They form a nearly perfect square 

 (about 35" on a side). On same parallel as ij Virgiuis, and followino- 

 it about 1 0"\ 



c suspected object — faint and nebulous — outline quite regular.

Set rough cir- 

 cle at 0° so as to 

 bring small trian- 

 gle in centre of field of finder. 



a precedes b 8^2Il::• 



b precedes c lo^6 ± O'.OT at 17''.5. 



1878, Feb. 5.6. — Object fixed. 





This morning's search terminates with this parallel. 

 Jan. 14.7. — Suspected object c (Jan. 11.7) fixed. 

 A nebulous cometary mass a (faint and irregular).

Elongated object first seen Jan. 5.7 is a nebula. I think it is Her- 

 schel (G. C. 277G).
