No sensible change since 1867. No proper motion found for 
the principal star. I have connected an exceedingly faint star, 
which was difficult to measure on each night.

H 2217 is in the sf part of h 310, which Herschel calls a 
“curious knot of stars.” There are several small pairs here; 
the one measured corresponds in all respects to the description 
in H.
