              A NON-EXISTENT SUSPECTED VARIABLE

   One of us (W.P.B.) recently noted that star No. 4527
in the Catalogue of Stars Suspected of Variability, 
announced by Ross in 1928, agreed fairly closely in position
with the Mira variable CN Aquilae. The suspicion that the
two objects might be identical was heightened by the fact
that CN Aquilae should have been at maximum light at the
time of Ross' positive observation. Inspection of the 
original plates used by Ross (by W.v.A.) leaves no doubt: that
his star was, in fact, CN Aquilae. Suspected variable No.
4527 thus does not exist.
