I am editing a new edition of PLEASURES OF THE TELESCOPE (1901) by
Garrett Serviss and adding updated nomenclature. There is one reference
I am uncertain about, a multiple star in Libra:

At the point marked A on the map is a curious multiple star, sometimes
referred to by its number in Piazzi's catalogues as follows: 212 P.
xiv. ...


That multiple star also is mentioned -- with the exact same Piazzi
designation -- in Admiral William H. Smyth's _The Bedford Catalogue_,
on page 329 of the Willmann-Bell reprint (1986).

And both your proposed matches are indeed correct; this system has been
tagged H 28, Hh 457, Sh 190. Its more modern identifier is ADS 9446.
