THE following is the Method I made use of and was happy enough to succeed in. I suspended a Poker in silk Lines; at the Handle of which I hung several little Bundles of white Thread, the Extremities of which were about a Foot at right Angles from the Poker. Among these Threads, which were all attracted by the rubbed Tube, I excited the greatest electrical Fire I was capable, whilst an Assistant near the End of the Poker held in his Hand a Spoon, in which were the warm Spirits. Thus the Thread communicated the Electricity to the Poker, and the Spirit was fired at the other End. It must be observ'd in this Experiment, that the Spoon with the Spirit must not touch the Poker; if it does, the Electricity without any flashing is communicated to the Spoon, and to the Assistant in whose Hand it is held, and so is lost in the Floor. By these Means, I fired several Times not only the ætherial Liquor or Phlogiston of _Frobenius_ and rectified Spirit of Wine, but even common proof Spirit. These Experiments, as I before observ'd, were made last _Friday_ Night, the Air being perfectly dry. _Sunday_ proved wet and _Monday_ somewhat warm, so that the Air was full of Vapour; Wind South-West and cloudy. Under these Disadvantages, on _Monday_ Night I attempted again my Experiments; they succeeded, but with infinitely more Labour than the preceeding, because of the Unfitness of the Evening for such Trials. _Your Candour_ will not permit you to think my Minuteness trivial, with Regard to the Circumstances of the Weather, who know, how many Things must concur to make these Experiments succeed. I shall wait with Impatience for a proper Opportunity to have these Experiments repeated in your Presence, and am, with the utmost Respect, _Sir, your most obedient,_ _humble Servant_, W. WATSON. _Aldersgate-Street, March 27. 1746._ TO THE ROYAL SOCIETY. GENTLEMEN, I lately acquainted you, that I had been able to fire Spirit of Wine, _Phlogiston_ of _Frobenius_, and common proof Spirit, by the Power of Electricity. Since which (till Yesterday) we have had but one very dry fine Day; _viz._ _Monday, April 15_. Wind E. N. E.; when about four o'Clock in the Afternoon, I got my _Apparatus_ ready, and fired the Spirit of Wine four Times from the Poker as before, three Times from the Finger of a Person electrified, standing upon a Cake of Wax, and once from the Finger of a second Person standing upon Wax, communicating with the first by means of a walking Cane held between their Arms extended. The horizontal Distance in this Case between the glass Tube and the Spirit was at least ten Feet.
