This star is identical with DM (27 0 ) 1477 (9.5). The place 
(for 1900) is from an astrographic plate taken 1908.08. The 
Oxford proper motion is :

In the first measures the distances differ as much as i"3, so 
the close agreement with the present result is rather accidental.

I do not find any proper motion assigned to either of these 
stars. The smaller is Lalande 15213. Some of the meridian 
positions are:

This place (for 1900) is from a plate of the Oxford Astro- 
graphic Catalogue taken 1908.08. From a comparison of this 
with an earlier photograph, the proper motion is given: 
0" 184 
in I46 ?o 
There are no catalogue stars near enough for direct com- 
parison with the micrometer.
