I was to learn mathematics of the famous blind professor Sanderson.  I had not frequented him a fortnight, before he said to me, “Young man, it is cheating you to take your money:  believe me, you never can learn these things; you have no capacity for them."- I can smile now, but I cried then with mortification.  The next step, in order to comfort myself, was not to believe him : I could not conceive that I had not talents for any thing in the world.  I took, at my own expense, a private instructor,(8) who came to me once a-day for a year.  Nay, I took infinite pains, but had so little capacity, and so little attention, (as I have always had to any thing that did not immediately strike my inclination) that after mastering any proposition, when the man came the next day, it was as new to me as if I had never heard of it ; in short, even to common figures, I am the dullest dunce alive.  I have often said it of myself, and it is true, that nothing that has not a proper Dame of a man or
           a woman to it, affixes any idea upon my mind.  I could
remember who was King Ethelbald’s great aunt, and not be sure whether she lived in the year 500 or 1500.  I don’t know whether I ever told you, that when you sent me the seven gallons of drams, and they were carried to Mr. Fox by mistake for Florence wine, I pressed @im to keep as much as he liked:  for, said I, I have seen the bill of lading, and there is a vast quantity.  He asked how much?  I answered seventy gallons; so little idea I have of quantity.  I will tell you one more story of myself, and you will comprehend what sort of a head I have!  Mrs. Leneve said to me one day, “There is a vast waste of coals in your house ; you should make the servants take off the fires at night.”  I recollected this as I was going to bed, and, out of economy, put my fire out with a bottle of Bristol water!  However, as I certainly will neglect nothing to oblige you, I went to Sisson and gave him the letter.  He has undertaken both the engine and the drawing, and has promised the utmost care in both.  The latter, he says, must be very large, and that it will take some time to have it performed very accurately.  He has promised me both in six or seven weeks.  But another time, don’t imagine, because I can bespeak an enamelled bauble, that I am fit to be entrusted with the direction of the machine at Marli.  It is not to save myself trouble, for I think nothing so for you, but I would have you have credit, and I should be afraid of dishonouring you.

There! there is the King of Prussia has turned all our war and
                    peace topsy-turvy !  If Mr. Pitt Will conquer
Germany too, he must go and do it himself.  Fourteen thousand soldiers and nine generals taken, as it were, in a partridge net! and what is worse, I have not heard yet that the monarch owns his rashness.(9) As often as he does, indeed, he is apt to repair it.  You know I have always dreaded Daun—­one cannot make a blunder but he profits of it-and this ’ just at the moment that we heard of nothing but new bankruptcy in France.  I want to know what a kingdom is to do when it is forced to run away?
