William Herschel discovered NGC 4352 = H II-64 = h1227 on 15 Mar 1784 (sweep 174) and logged "F, vS." His RA was 1 min too large (roughly the same error was made on this sweep with several others objects). JH measured an accurate RA and logged "vF; S; lE.", though he used his father's erroneous RA in the GC. Heinrich d'Arrest independently found the nebula on 23 Mar 1865, measured an accurate RA again and Dreyer catalogued it again as GC 5642. Bigourdan noted the equivalence and Dreyer combined the two GC and GCS entries (2929 and 5642) into NGC 4352.

400/500mm - 17.5" (4/18/87): fairly faint, small, oval ~E-W, small brighter core. NGC 4330 lies 14' NW.
