Wilhelm Tempel discovered NGC 4322, along with NGC 4323 and NGC 4327, in 1882, during an observation of M100. In the text section of his 5th discovery list (AN 2439) he mentions "on my drawing are three other very faint nebula in the vicinity, two north and close to M100 and the third south of [NGC 4328]." There is only a single galaxy close north of M100 and none to the south of[NGC 4328. RNGC and MCG equate NGC 4322 = NGC 4323 although Corwin suggests NGC 4323 should apply to the (single) galaxy and NGC 4322 to a star further west, whose position is given here. This assignment for NGC 4322 is really just a guess, though, so I've left the designation as "Not Found". Of course, the galaxy listed here could be identified as NGC 4322 with NGC 4323 left as "Not Found".

600/800mm - 24" (5/22/17): this number possibly applies to a 13th magnitude star 5.7' NW of the center of M100 and 4.8' due west of NGC 4323 (CGCG 099-031). This single star clearly appeared stellar 200x-375x and was bright enough that I'm surprised if Tempel would have confused it as a nebulous object unless the seeing was very poor. Most catalogues assign both NGC 4322 and 4323 to the single galaxy to the north of M100.
