| Title | Letter from [William George] Armstrong, Cragside, Rothbury, to [Alan Archibald Campbell] Swinton, 66 Victoria [Street], London, S.W |
| Creator | Armstrong; William George (1810 - 1900); Baron Armstrong of Cragside; armaments manufacturer and industrialist |
| Date | 16 May 1892 |
| Description | In reference to the reading of his paper at the Royal Society, he intends to show the production of dust figures to the audience if he can manage it and requires an induction coil and batteries to work it. He obtained the best result in the dust experiment with the combined action of 3 of his coils joined in parallel and discharged by a hand contact breaker (alcoholic), which requires three batteries. Would prefer a single coil that would give the equal effect or nearly so. Contemplates having one larger coil than at present as well as a one that would give a 12 inch spark adn 3 times the quantity of one of his present 10 1/4 inch coils. Asks Swinton to contact Mr [Alfred] Apps for suggestions. |
