LINE INTEGRALS OF NE AND NE2 AT HIGH GALACTIC LATITUDE

Recent discoveries of pulsars in high-\z\ globular clusters have made it possible for the first time to compare unambiguously the value of integral n(e)ds with the value of integral n(e)2ds along four "random" lines of sight at high \b\. The results imply that the diffuse interstellar H+ is clumped into regions which have an average electron density n(e) almost-equal-to 0.08 cm-3 and which occupy a fraction integral greater-than-or-similar-to 0.2 of the volume within a 2 kpc thick H+ layer. The similarity of the results for each of the widely separated directions suggests that there is little variation in the properties of the gas within the solar neighborhood. There is some evidence that the filling fraction increases with distance \z\ away from the Galactic midplane.
