Holden found 22 NGC-objects with the 15.6" f/15.6 Clark-refractor, erected in 1881 at Washburn Observatory, Madison, Wisc. 19 ojects were new. NGC 3979 was also found in 1886 by Swift at Warner Observatory and a second time by him from Echo Mountain as IC 2976. There are 5 objects in Holden's list, left out by Dreye: No. 8 = NGC 4592 (W. Herschel), No. 9 = NGC 4997 (Burnham), No. 18 ("coarse cluster"), No. 19 ("black circular hole in the Milky Way") and No. 20 ("coarse cluster").
