Editing Fleeming Jenkin (section)

===Partnership with Thomson and Varley===
"Jenkin's position at Edinburgh led to a partnership in cable work with Varley and Thomson, whom he always admired. Jenkin's practical and businesslike abilities were of assistance to Thomson, relieving him of routine and sparing his time for other work. In 1870 the [[siphon recorder]] for tracing a cablegram in ink instead of merely flashing it by the moving ray of the [[mirror galvanometer]], was introduced on long cables and became a source of profit to Jenkin and Varley as well as to Thomson, its inventor."<ref name=munro/>{{rp|¶ 51}}

"In 1873 Thomson and Jenkin were engineers for the [[Western and Brazilian cable]]. It was manufactured by [[Hooper & Co.]], of [[Millwall]] and the wire was coated with [[india rubber]], then a new insulator. The ''Hooper'' left [[Plymouth]] in June, and after touching at [[Madeira]], where Thomson was up 'sounding with his special toy' (the pianoforte wire) 'at half-past three in the morning,' they reached [[Pernambuco]] by the beginning of August, and laid a cable to [[Pará]]."<ref name=munro/>{{rp|¶ 52}}

"During the next two years the [[Brazil]]ian system was connected to the [[West Indies]] and the [[Río de la Plata]] but Jenkin was not present on the expeditions. While engaged in this work, the ill-fated ''La Plata'', carrying cable from the [[Siemens AG]] company to [[Montevideo]], sank in a [[cyclone]] off [[Ushant]] with the loss of nearly all her crew. The [[Mackay-Bennett Atlantic cables]] were also laid under their charge."<ref name=munro/>{{rp|¶ 53}}
