Discovery of interstellar Ge, Ga, and Kr is reported. Several intercombination lines of Fe II are detected. The depletion is most pronounced in Ca, Ti, and V. The highly ionized gas C IV and Si IV is not coextensive with the Si II and C II gas nor with the 0 VI gas. The molecular gas (CO) shows very small velocity dispersion (b~l km/sec).
