TitleLetter from O J L [Oliver Joseph Lodge], Mariemont, Edgbaston, to [Joseph] Larmor
CreatorLodge; Sir Oliver Joseph (1851-1940); British physicist
RecipientLarmor; Sir Joseph (1857-1942); Irish theoretical physicist
Date27 September 1903
DescriptionLarmor's activity is 'splendid' and Lodge has been impressed with [Adolphe] Carnot 'as a howling swell'. Lodge discusses reverberation inside a hollow cylinder, referring Larmor to his 1894 work. The only receiver on anything like the plan was an old model of the rods and cones of the eye. He describes his experimental apparatus, which included copper screens to eliminate stray waves. He thinks this might be tried for telegraphy but it would be difficult to get sufficient power. Syntonic devices are too insensitive and tuning has to be 'fearfully accurate'. He may try it, asking if a rectangular cavity would do as well as a cylinder, and noting that the line of oscillation should be vertical for telegraphic waves.
