We have found a scatter correlation between the HI integrated intensity ($W_{\\rm HI}$) and $\\tau_{353}$ in the Chamaeleon region. The scattering has been examined in terms of possible large optical depth in HI emission ($\\tau_{\\rm HI}$) using a total column density ($N_{\\rm H}$) model based on $\\tau_{353}$.
