Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. If any of my readers, on seeing that my whole superstructure is founded upon phrenology, are inclined to reject it on that account, with the remark that they do not believe in phrenology, my reply is that I ask no one to believe in it.
