William Petty,
History of the Down Survey
(1851)
“ Petty as possessing the faculty which would probably have commanded success in any undertaking or career to which he had devoted himself. That he should have ventured upon one so remote from anything to which his attention had previously been directed, may be taken as great boldness on his part, but it enhances our surprise at the success of the work. It would be no easy task in our own day, to accomplish in thirteen months, even a traverse survey in outline, of 5,000,000 acres in small divisions, and it was immeasurably greater then. ”
