is held in the hand, and rise in the other as a jet or fountain; when it is all in the other, it begins to boil, as it were, by the vapor passing up through it; and the instant it begins to boil, a sudden coldness is felt in the ball held; a curious experiment this, first observed and shown by Mr. Nairne. There is something in it similar to the old observation, I think mentioned by Aristotle, that the bottom of a boiling pot is not warm; and perhaps it may help to explain the fact; if indeed it be a fact.

      When the water stands at an equal height in both these balls, and all at rest, if you wet one of the balls by means of a feather dipped in spirit, though that spirit is of the same temperament as to heat and cold with the water in the glasses, yet the cold occasioned by the evaporation of the spirit from the wetted ball will so condense the vapor over the water contained in that ball, as that the water of the other ball will be pressed up into it, followed by a succession of bubbles, till the spirit is all dried away. Perhaps the observations on these little instruments may suggest and be applied to some beneficial uses. It has been thought, that water reduced to vapor by heat was rarefied only fourteen thousand times, and on this principle our engines for raising water by fire are said to be constructed; but, if the vapor so much rarefied from water is capable of being itself still farther rarefied to a boundless degree, by the application of heat to the vessels or parts of vessels containing the vapor (as at first it is applied to those containing the water), perhaps a much greater power may be obtained, with little additional expense. Possibly, too, the power of easily moving water from one end to the other of a movable beam (suspended in the middle like a scale-beam) by a small degree of heat, may be applied advantageously to some other mechanical purposes.

      The magic square and circle, I am told, have occasioned a good deal of puzzling among the mathematicians here; but no one has desired me to show him my method of disposing the numbers. It seems they wish rather to investigate it themselves. When I have the pleasure of seeing you, I will communicate it.

      With singular esteem and respect, I am, dear Sir,

      Your most obedient humble servant,

       B. Franklin.

      CCCXXXVI: PETITION OF THE LETTER Z

      From The Tatler, No. 1778.

       To the Worshipful Isaac Bickerstaff, Esquire, Censor-General.

      The petition of the letter Z, commonly called Ezzard, Zed, or Izard, most humbly showeth:

      That your petitioner is of as high extraction, and has as good an estate, as any other letter of the Alphabet;

      That there is therefore no reason why he should be treated as he is, with disrespect and indignity;

      That he is not only actually placed at the tail of the Alphabet, when he had as much right as any other to be at the head; but it is by the injustice of his enemies totally excluded from the word WISE; and his place injuriously filled by a little hissing, crooked, serpentine, venomous letter, called S, when it must be evident to your worship, and to all the world, that W, I, S, E, do not spell Wize, but Wise.

      Your petitioner therefore prays, that the Alphabet may by your censorial authority be reversed; and that in consideration of his long-suffering and patience he may be placed at the head of it; that S may be turned out of the word Wise, and the petitioner employed instead of him.

      And your petitioner, as in duty bound, shall ever pray, &c., &c.

      Mr. Bickerstaff, having examined the allegations of the above petition, judges and determines that Z be admonished to be content with his station, forbear reflections upon his brother letters, and remember his own small usefulness, and the little occasion there is for him in the Republic of Letters since S, whom he so despises, can so well serve instead of him.

      

      CCCXXXVII. TO WILLIAM FRANKLIN

      London, 2 July, 1768.

      Dear Son:—

      Since my last I have received yours of May 10th, dated at Amboy, which I shall answer particularly by next week’s packet. I purpose now to take notice of that part wherein you say it was reported at Philadelphia I was to be appointed to a certain office here, which my friends all wished, but you did not believe it for the reasons I had mentioned. Instead of my being appointed to a new office, there has been a motion made to deprive me of that I now hold, ^{Ref. 008} and, I believe, for the same reason, though that was not the reason given out, viz., my being too much of an American; but, as it came from Lord Sandwich, our new postmaster-general, who is of the Bedford party, and a friend of Mr. Grenville, I have no doubt that the reason he gave out, viz., my non-residence, was only the pretence, and that the other was the true reason; especially as it is the practice in many other instances to allow the non-residence of American officers, who spend their salaries here, provided care is taken that the business be done by deputy or otherwise.

      The first notice I had of this was from my fast friend, Mr. Cooper, secretary of the treasury. He desired me, by a little note, to call upon him there, which I did, when he told me that the Duke of Grafton had mentioned to him some discourse of Lord Sandwich’s, as if the office suffered by my absence, and that it would be fit to appoint another, as I seemed constantly to reside in England; that Mr. Todd, secretary of the post-office, had also been with the Duke, talking to the same purpose, &c.; that the Duke wished him (Mr. Cooper) to mention this to me, and to say to me, at the same time, that, though my going to my post might remove the objection, yet, if I choose rather to reside in England, my merit was such in his opinion as to entitle me to something better here, and it should not be his fault if I was not well provided for. I told Mr. Cooper that, without having heard any exception had been taken to my residence here, I was really preparing to return home, and expected to be gone in a few weeks; that, however, I was extremely sensible of the Duke’s goodness in giving me this intimation, and very thankful for his favorable disposition towards me; that, having lived long in England, and contracted a friendship and affection for many persons here, it could not but be agreeable to me to remain among them some time longer, if not for the rest of my life; and that there was no nobleman to whom I could, from sincere respect for his great abilities and amiable qualities, so cordially attach myself, or to whom I should so willingly be obliged for the provision he mentioned, as to the Duke of Grafton, if his Grace should think I could, in any station where he might place me, be serviceable to him and to the public.

      Mr. Cooper said he was very glad to hear I was still willing to remain in England, as it agreed so perfectly with his inclinations to keep me here; wished me to leave my name at the Duke of Grafton’s as soon as possible, and to be at the treasury again the next board day. I accordingly called at the Duke’s and left my card; and when I went next to the treasury, his Grace not being there, Mr. Cooper carried me to Lord North, chancellor of the exchequer, who said very obligingly, after talking of some American affairs, “I am told by Mr. Cooper that you are not unwilling to stay with us. I hope we shall find some way of making it worth your while.” I thanked his Lordship, and said I should stay with pleasure, if I could any ways be useful to government. He made me a compliment and I took my leave, Mr. Cooper carrying me away with him to his country-house at Richmond to dine and stay all night.

      He then told me that Mr. Todd had been again at the Duke of Grafton’s, and that upon his (Mr. Cooper’s) speaking in my behalf, Mr. Todd had changed his style, and said I had, to be sure, a great deal of merit with the office, having by my good management regulated the posts in America so as greatly to increase the revenue; that he had had great satisfaction in corresponding with me while I was there, and he believed they never had a better officer, &c. The Thursday following, being the birthday, I met with Mr. Todd at court. He was very civil, took me with him in his coach to the King’s Arms in the city, where I had been invited to dine by Mr. Trevor, with the gentlemen of the post-office; we had a good deal of chat after dinner between us two, in which he told me Lord Sandwich (who was very sharp) had taken notice of my stay in England, and said, “If one could do the business why should there be two?” On my telling Mr. Todd that I was going
