coloured copy of Petty's maps in the British Museum, and also an
uncoloured copy, with the first five maps varying from those in the
coloured copy, and giving a General Map of Ireland, followed by Maps
of Leinster, Munster, Ulster, and Connaught. There was afterwards
published in duodecimo, without date, "A Geographical Description of
ye Kingdom of Ireland, collected from ye actual Survey made by Sir
William Petty, corrected and amended, engraven and published by Fra.
Lamb." This volume gives as its contents, "one general mapp, four
provincial mapps, and thirty-two county mapps; to which is added a
mapp of Great Brittaine and Ireland, together with an Index of the
whole."

At the Restoration William Petty accepted the inevitable change, and
continued his service to the country. He was knighted by Charles
the Second, and appointed in 1661 Inspector-General of Ireland. He
entered Parliament. He was one of the first founders of the Royal
Society, established at the beginning of the reign of Charles the
Second; and the outcome of these scientific studies along the line
marked out by Francis Bacon, which had been actively pursued in
Oxford and at Gresham College. In 1663 he applied his ingenuity to
the invention of a swift double-bottomed ship, that made one or two
passages between England and Ireland, but was then lost in a storm.

In 1670 Sir William Petty established on his lands at Kerry the
English settlement at the head of the bay of Kenmare. The building
of forty-two houses for the English settlers first laid the
foundations of the present town of Kenmare. "The population,"
writes Lord Macaulay, "amounted to a hundred and eighty. The land
round the town was well cultivated. The cattle were numerous. Two
small barks were employed in fishing and trading along the coast.
