\caption{Galactic (foreground) atomic column densities derived via 
the construction of apparent column density velocity 
profiles and subsequent line profile integration.
Error in log~$N$ is 0.02~dex for \ion{Na}{i}, \ion{Ti}{ii} and \ion{Ca}{ii}~K.
Adopted line transition wavelengths and oscillator strengths from \citet{2003ApJS..149..205M}.
Column densities toward \object{Sk~191} and \object{AzV~242} suffer significantly from line saturation. The smaller values for \ion{Ca}{ii}/\ion{Na}{i} in the Galaxy are consistent with a~higher~UV in the SMC. Larger Galactic values for \ion{Ca}{ii}/\ion{Ti}{ii} by about 0.2~dex, indicate a~higher sensitivity to the second
ionisation potential in the SMC compared to the Galaxy.}
