Sharp (1908) lists Tinker, who lived at Staleybridge, as one of the earlier students who ‘left any records of their labours, in fact many of them owed the only education they possessed to that training which Nature herself afforded... These men were the first of the group of whom any record exists, and had died out by the middle of the last century.’ He states that Tinker’s collection existed at that time in Liverpool Museum.
