another inventor in an age which however has not been allotted any eminent rank in the history of arts. He naturally follows Kirkall, as there was some analogy in their pursuits. The former, if I may say so, attempted to print drawings, the latter to print paintings.

As he was much an enthusiast, perhaps like most enthusiasts he was both one and t'other.

He distributed them by a kind of lottery, but the subscribers did not find their prizes much valued. Yet surely the art was worth improving, at least in a country so fond of portraits.
