Mr. D’Arrest, in an article published in No. 1898 Astr. Nachr.

The same astronomer has announced, in No. 1407 Astr. Nachr., 
that Sir John Herschel is preparing a new general catalogue of 
nebul from observations both ancient and modern, and he gives 
on this occasion a list. of corrections of the catalogue of 18338, 
resulting from his own observations and those of Messrs. Auwers 
and Marth, which Sir John Herschel will beable to make use of 
in his new work. 
The later numbers of the Monthly Notices of the Astronomi- 
cal Society of London contain no articles relating to nebule. I 
will cite only one article by F. Abbott, dated at his private ob-
