   Thanks!  Upon examination of the volume, I have been surprised to find
many of Luyten's variables remain uncataloged, even not given for NSV numbers.

   900.1936 = V735 Sgr
   901.1936 = V788 Sgr, Mira star, but no corresponding IRAS source.
              Many Mira stars around.
   902.1936 = ?
   903.1936 = ? IRAS source close to the position
   904.1936 = ? IRAS sources a few arcmin away
   905.1936 = ? IRAS sources a few arcmin away
   906.1936 = ? The carbon star CS 3934 is a few arcmin away
   907.1936 = V1978 Sgr  Mira star.  No certain ID.
   908.1936 = NSV 10773
   909.1936 = NSV 10778

   Some of other stars seem to have been re-identified: GCVS positions often
one to a few arcmin from the Luyten's coordinates.  These real objects tend
to lie south to the reported positions.  The extreme close coincidence of
Luyten's position and the currently cataloged position leaves serious
doubts on the identity.  I even wonder whether Vogt and Bateson actually
observed the star "in outburst state".  This reminds me of the V725 Aql
case.
