I enclose you Answers, such as my present Hurry of Business will permit me to make, to the principal Queries contain’d in your Favour of the 28th Instant, and beg Leave to refer you to the latter Piece in the printed Collection of my Papers for farther Explanation of the Difference between what are called Electrics per se, and Non Electrics. When you have had Time to read and consider those Papers, I will endeavour to make any other new Experiments you shall propose, that you think may afford farther Light or Satisfaction to either of us, and shall be thankful for such Remarks, Objections, &c. as may occur to you. I forget whether I wrote you, that I have melted brass Pins and Steel Needles, inverted the Poles of the magnetic Needles, given Magnetism and polarity to Needles that had none, and fired dry Gunpowder, by the Electric Stroke. I have five Bottles that contain 8 or 9 Gallons each, two of which charg’d, are sufficient for the above purposes; but I can charge and discharge them all together. There are no Bounds (but what Expence and Labour give) to the Force Man may raise and use in the Electric Way: For Bottle may be added to Bottle in infinitum, and all united and discharg’d together as One, the Force and Effect proportion’d to their Number and Size. The greatest known Effects of common Lightning, may, I think, without much Difficulty be exceeded in this way: Which a few Years since could not have been believed, and even now may seem to many a little extravagant to suppose. So we are got beyond the Skill of Rabelais’s Devils of two Year old, who, he humourously says, had only learnt to thunder and lighten a little round the Head of a Cabbage. I am, with sincere respect, Dear Sir, Your most obliged humble Servant
