Photometry of faint blue stars - IX
Stromgren uv by photometry is presented for 129 `faint blue' stars takenfrom various catalogues. The photometry is used to estimate photometric`classifications' for the stars, which indicate a mixture of hotsubdwarfs, horizontal-branch stars, metal-weak subdwarfs and so on.Attention is drawn to stars (from this paper and previous papers in theseries) which appear to be somewhat reddened. Some are probablybinaries, and others might be objects with peculiar colours, such ascataclysmic variables. One star, LB 9963, almost certainly falls intothe latter category. Two stars which, from their colours, are PopulationII A-F stars are variable; one of these, OM 89, is the known RR Lyraestar, VW Dor.

| Primarily Galactic stars with high radial velocity near the Magellanic Clouds
UBV photoelectric measurements and spectral types (sometimes revised)are presented for 54 mostly-foreground high-radial-velocity stars nearand between the SMC and LMC. The color-color diagram is shown to be verysimilar to that of Omega Cen. It is noted that four of the stars aresubdwarves, 23 stars are submetallic or horizontal branch stars, onestar is probably a member of the LMC, and the rest are population Istars of luminosity classes III-V. The density of high-velocityforeground stars towards the Magellanic Clouds appears to be about 20times higher than in other directions of similar galactic latitude.
