Mr. Sikes of Paris has been so obliging as to undertake the care of delivering a Book to you. It is directions for using my Patent Electrical Machine which I hope before this you have received safe. There are some experiments in the Philosophical part, which I hope will give you pleasure, as they tend to confirm your Theory of Electricity. If it were necessary to add any thing more to your account of the similitude of Lightning and Electricity. I think the experiment which I have published in the Phil. Trans. Vol: 70 for the year 1780 of the Effect of Electricity in shortning of wiere and likewise the same effect which I have since observed produced by Lightning which will be published in the next Phil: Trans: is another confirmation.

I have lately met with a circumstance of the effects of Lightning which I never heard of before. My Authority is part of a letter from the Duke of Marlborough to Professor Hornsby of Oxford who is now at Ramsgate for his Health, where he read it to me. A Gentleman told the Duke that in the Storm of Lightening which happened lately in Oxfordshire he had several of his Sheep killed under a Tree. I think it was thirteen and that when they come to examine them they found that every one of them had the Balls of their eyes forced out.

I know your time is much taken up, otherwise I should esteem it greatly if you would favor with a line Your much obliged Humble Servant.
