He was employed as actuary to the parliamentary commission on factories, and as sub-commissioner on those relating to handloom-weaving and the condition of women and children in collieries.

He was a fellow of the Geological Society of London, to which he made numerous communications, and from 1823 a corresponding member of the Society of Scottish Antiquaries.|
