OAO-2 Observations of the Near Ultraviolet Extinction Featureese stars. The position of the maximum of the bump is within ± 40Å of 2175Å in all cases. A color excess between the wavelengths 2175 Å and 3500 Å was determined for all 40 stars. This color excess, which is a measure of the bump strength, correlates very well with .except for stars associated with nebulosity.

Diffuse Interstellar Features in the Spectra of Dust-Embedded Starsld stars in the same direction. The equivalent widths of the lines are all strongly correlated with each other and with .., but there is virtually no correlation with D line strength for these stars. The wavelength positions and half-widths of the diffuse lines appear to be the same for all stars studied.

The Ultraviolet Surface Brightness of Reflection Nebulae and the Albedo of Interstellar Grainsllar grains below 2000 Å occurs in individual reflection nebulae as well as in the general interstellar medium. Evidence for differences in the composition and size distribution of grains due to variations in the local radiation field is presented.

Some Scattering Problems of Interstellar GrainsSome general effects of size, shape, and material on the scattering properties of small particles are considered with a view to determining their relative importance to interstellar dust interpreatations.

Variations of Interstellar Ultra-Violet AbsorptionIt is shown that mixtures of graphite core-ice mantle grains with large and small mean size and graphite grains provide good fits to the observed interstellar extinction curve.

Interstellar Dust: Observations in the Ultraviolet and their InterpretationsRecent observations of interstellar extinction and diffuse galactic light in the ultraviolet are interpreted in terms of a bi-modal size distribution of interstellar grains.
