Willhelm Tempel discovered NGC 4164 = T I-37 (as well as paper V) and placed it 2.5' south of d'Arrest's "nova" [NGC 4165]. He commented "but it is strange that he has not seen the second companion", though I'm not surprised as this galaxy is quite faint. Interesting, the LdR observation of NGC 4168 on 17 Feb 1855 reads "vB, R, bM, 2 stars preceding." One of the "stars" preceding must be NGC 4164, but it was seen as stellar.

This galaxy is mentioned in the UGC notes for NGC 4168, but not identified as NGC 4164.

400/500mm - 17.5" (1/23/88): extremely faint, very small, round, only visible with averted vision. Faintest in a trio and located 3' SSW of NGC 4165 and 2.9' W of NGC 4168.
