At the Annual Show (September) of the Royal Cornwall Polytechnic Society in 1846, the artist was awarded the Bronze Medal in the Oils Section for his Landscape. Wood notices a W Bath (fl 1840-1851) who may be the same painter, as a London landscape painter who exhibited at the RA, BI and SS. It was not unusual for professional artists outside of Cornwall to send-in for RCPS Exhibitions, but conceivably this could have been a county person of the same surname.
