A simple analysis of five high-latitude early-type stars is presented. Reticon spectra and Strömgren photometry are used to determine Teff and log g from "Kiel diagrams" and values of V sin i are estimated from He I lines. The results are checked by fitting Kurucz (1979) profiles to the observed Hγ and Hδ profiles. Four stars appear spectroscopically normal although one might be subluminous; implied distances from the galactic plane are between 3 and 15 kpc. One star, TONS 308, could be a spectrum variable.
