Jan. 16, 1850. A F. spiral. Mar. 20, 1854. A F. * immediately f. ; spiral left-handed; 
very faintly seen ; night bad. 
685 seems like 393, but instead of the * having an approach to a nucleus. Jan. 30, 1856. 
About 5' sp. 684 is a wF. ray, extending n, and s. 684 has a B. central nucleus, 
with a sensible disk. 
Suspected spiral. 
Spiral. Feb. 1, 1856. The neby. connecting the three principal knots is wF, but no 
doubt of its existence. Sketch made. See fig. 13, Plate XXVII,

According to Herschel, the distance from 692 to 
693 is 4' ; this should be carefully looked M 
after. Mar. 22, 1857. Sketched; a and 
y r ; nucleus of S appears eccentric. See fig. 14, Plate XXVII. 
March 3, 1850. Probably a F. spiral. March 24, 1857. in f . end ; dark spaces through- 
out its length. 
f iFeb. 16, 1855. They form an obtuse-angled triangle ; the p. one is accompanied by 2 
\ minute *s, one n. and the other nf ; the next has also a minute * as a comp. nf.
