Title: On structural patterns in H II regions

High-resolution photographs of H II regions show that a large number of stars embedded in the nebulosities appear to be surrounded by emply spaces. This phenomenon seems to be quite common but has escaped attention up to now. The effect is not a photographic one, nor does it arise in the half-tone reproduction processes employed in publications, but no satisfactory explanation is apparent. 9 refs.
