Supped at Sir William Petty's, with the Bishop of Salisbury, and divers honorable persons.[Pg 100] We had a noble entertainment in a house gloriously furnished; the master and mistress of it were extraordinary persons. Sir William was the son of a mean man somewhere in Sussex, and sent from school to Oxford, where he studied Philosophy, but was most eminent in Mathematics and Mechanics; proceeded Doctor of Physic, and was grown famous, as for his learning so for his recovering a poor wench that had been hanged for felony; and her body having been begged (as the custom is) for the anatomy lecture, he bled her, put her to bed to a warm woman, and, with spirits and other means, restored her to life. The young scholars joined and made a little portion, and married her to a man who had several children by her, she living fifteen years after, as I have been assured. Sir William came from Oxford to be tutor to a neighbor of mine; thence, when the rebels were dividing their conquests in Ireland, he was employed by them to measure and set out the land, which he did on an easy contract, so much per acre. This he effected so exactly, that it not only furnished him with a great sum of money; but enabled him to purchase an estate worth £4,000 a year. He afterward married the daughter of Sir Hardress Waller; she was an extraordinary wit as well as beauty, and a prudent woman.
Sir William, among other inventions, was author of the double-bottomed ship, which perished, and he was censured for rashness, being lost in the Bay of Biscay in a storm, when, I think, fifteen other vessels miscarried. This vessel was flat-bottomed, of exceeding use to put into shallow ports, and ride over small depths of water. It consisted of two distinct keels cramped together with huge timbers, etc., so as that a violent stream ran between; it bore a monstrous broad sail, and he still persists that it is practicable, and of exceeding use; and he has often told me he would adventure himself in such another, could he procure sailors, and his Majesty's permission to make a second Experiment; which name the King gave the vessel at the launching.
The Map of Ireland made by Sir William Petty is believed to be the most exact that ever yet was made of any country. He did promise to publish it; and I am told it has cost him near £1,000 to have it engraved at[Pg 101] Amsterdam. There is not a better Latin poet living, when he gives himself that diversion; nor is his excellence less in Council and prudent matters of state; but he is so exceedingly nice in sifting and examining all possible contingencies, that he adventures at nothing which is not demonstration. There was not in the whole world his equal for a superintendent of manufacture and improvement of trade, or to govern a plantation. If I were a Prince, I should make him my second Counsellor, at least. There is nothing difficult to him. He is, besides, courageous; on which account, I cannot but note a true story of him, that when Sir Aleyn Brodrick sent him a challenge upon a difference between them in Ireland, Sir William, though exceedingly purblind, accepted the challenge, and it being his part to propound the weapon, desired his antagonist to meet him with a hatchet, or axe, in a dark cellar; which the other, of course, refused.
Sir William was, with all this, facetious and of easy conversation, friendly and courteous, and had such a faculty of imitating others, that he would take a text and preach, now like a grave orthodox divine, then falling into the Presbyterian way, then to the fanatical, the Quaker, the monk and friar, the Popish priest, with such admirable action, and alteration of voice and tone, as it was not possible to abstain from wonder, and one would swear to hear several persons, or forbear to think he was not in good earnest an enthusiast and almost beside himself; then, he would fall out of it into a serious discourse; but it was very rarely he would be prevailed on to oblige the company with this faculty, and that only among most intimate friends. My Lord Duke of Ormond once obtained it of him, and was almost ravished with admiration; but by and by, he fell upon a serious reprimand of the faults and miscarriages of some Princes and Governors, which, though he named none, did so sensibly touch the Duke, who was then Lieutenant of Ireland, that he began to be very uneasy, and wished the spirit laid which he had raised, for he was neither able to endure such truths, nor could he but be delighted. At last, he melted his discourse to a ridiculous subject, and came down from the joint stool on which he had stood; but my lord would not have him preach any more. He never[Pg 102] could get favor at Court, because he outwitted all the projectors that came near him. Having never known such another genius, I cannot but mention these particulars, among a multitude of others which I could produce. When I, who knew him in mean circumstances, have been in his splendid palace, he would himself be in admiration how he arrived at it; nor was it his value or inclination for splendid furniture and the curiosities of the age, but his elegant lady could endure nothing mean, or that was not magnificent. He was very negligent himself, and rather so of his person, and of a philosophic temper. "What a to-do is here!" would he say, "I can lie in straw with as much satisfaction."
He is author of the ingenious deductions from the bills of mortality, which go under the name of Mr. Graunt; also of that useful discourse of the manufacture of wool, and several others in the register of the Royal Society. He was also author of that paraphrase on the 104th Psalm in Latin verse, which goes about in MS., and is inimitable. In a word, there is nothing impenetrable to him.
