Nebula in M o n o c e r o s in which the star 7.3 mag. BD. - 10?1848 is involved together with several other faint stars. The nebula is irregularly round, bright, with a wide nebulous band across it in s. f. to n. p. direction. The nebula is about 1 3 minutes of arc in diameter; coordinates of the Star for the epoch 1855 RA. 6h 57"33!6, Dec. south 10' 14:4; mag. 7.3.

The nebula N.G.C. No.2403 H.V. 44 C a m e l o p a r d i RA. 7 h 2 i m , Dec. north 65" 50' is a bright right-hand spiral

with several bright stars involved and numerous stellar conden- sations in the spirals; resembles M 33 Trianguli; major diameter from s . f. to n. p. about 18 minutes of arc in length.

The nebula N. G. C. 2404 (Bigourdan) appears to be one of the numerous nebulous stars which form parts of this spiral nebula. There are also other small faint stars involved in nebulosity within the distance of one degree of this nebula.

Moonlight has now closed observations. By computing, from the entire series, the rate of

motion, with respect to the third order of differences, the probable errors of a determination would appear to be : + o h RA. and 2 " Decl. But this method of checking is only approximate, and the determinations are probably much sharper, since the Comet has been, in general, not a diffi- cult object to observe.
