Sketched 4 times. Feb. 19, 1855. 3 *s in it ; there is a mass of neby. f. the brightest 
part, with condensed portions through it. Disposed in curves ? The F. ray extends 
many minutes s, gradually fading away. Mar. 17, 1855. There seems to be a knot at 
p. extremity, in which the neb. terminates in that direction, and immediately s. of 
this knot is a little dark bay. The branch running f. from this curves round towards 
centre. See figure.

Mar. 30, 1856. Examined attentively for a long time ; it appears to be of the shape an- 
nexed, which exaggerates ; there can be no doubt of the bend 
upwards at a, and of the darkness about the nucleus ; S. 5!f at 
/3. Apr. 6, 1856. Seen pretty much as before ; the upward s 
bend at a is at a right angle. The p. branch reaches as far n 
as y ; and I suspect a S. * there. Mar. 8, 1858. This night 
is not as good as some on which I observed this object last 
year, but I can confirm my previous observations as to its general shape.
