  We have carried out abundance analysis for a sample of high galactic latitude
supergiants in search of evolved stars. We find that HD 27381 has atmospheric
parameters and an abundance pattern very similar to that of the post-AGB star
HD 107369. HD 10285 and HD 25291 are moderately metal-poor and show the
influence of mixing that has brought the products of NeNa cycle to the surface.
The high galactic latitude B supergiant HD 137569 shows selective depletion of
refractory elements normally seen in post-AGB stars. We find that the high
velocity B type star HD 172324 shows moderate deficiency of Fe group elements
but the CNO abundances are very similar to that of disk B supergiants. The
observed variations in the radial velocities, transient appearance of emission
components in hydrogen line profiles and doubling of O I lines at 7774\AA
support the possibility of this star being a pulsating variable or a binary
star.
