J SHALL be very glad to know if you havetried the ex¬ periment I mentioned to you in London, concerning a large glafs bottle filled with warm water, and touching the furface all over with a non-eledric, in order to fee if the effed is not in that proportion. There is another experiment which I have fince thought of, which I wifh you would alfo try. I have fufpeded that the excited effluvia are not from the glafs globe but the body that rubs it, or however the greateft part. You may be fatisfied of this by holding in your hand along dry bottle by the neck, fo that the bottom thereof, to which one cf your leather cufhions is fixed, fhallprefs upon the globe after the common method. In this fituation you know the glafs between the cufhion and your hand will in¬ tercept any communication of thefe effluvia with the earth (if there naturally are any fuch in non~eledri.c bodies) for the fame reafon as it does eledrified bodies when fixed upon refin &c. I fancyy^ will produce little effect. If it fhould be the fame as before, then it is plain that the effluvia come from the globe of glafs. I am, &c. B. WILSON. An
