Inman's publications on personal hygiene are practical advice. On 21 October 1844 he became a member of the Literary and Philosophical Society of Liverpool, to whose
Proceedings he contributed papers, mainly on archæological subjects. He read widely, was no scholar, but wrote with ingenuity. From
Godfrey Higgins he derived the suggestion that the key to all mythology is to be sought in
phallic worship. On 5 February 1866 he first propounded this theory in a paper on
The Antiquity of certain Christian and other Names. The subject was pursued in other papers, and in three works on
Ancient Faiths, which he published between 1868 and 1876. •
