Observations are presented of high resolution interstellar Na D and K I (λ7699 A) line profiles towards 3 stars in the globular cluster M 10 and 2 field stars within 5deg of the cluster. The gas which is observed towards all the programme stars is dominated by a strong component at a velocity ≃-0.7km/s; the bulk of this gas is shown to lie at a distance ≲360 pc. Comparison is made with gas properties for adjacent high-latitude molecular clouds (Penprase 1993). The low-velocity gas apparently extends to distances well beyond the molecular clouds in this direction; there is, however, no evidence for additional gas components in the region between the nearby gas and the distant cluster. These observations extend our survey of the large-scale structure of the nearby gas in the general direction l≃10±5deg further into the northern Galactic hemisphere and we review the gas column density and velocity structure over the latitude range -25deg to +25deg.
