In 1861 Mr. Jenkin joined Mr. H. C. Ford as partner, and with 

 him for seven years he carried on an extensive practice in telegraphic 

 and general engineering. During the last two years of this partner- 

 ship Jenkin held the post of Professor of Engineering at University 

 College, London, and in 1868 the partnership was dissolved on account 

 of his appointment to fill the Chair of Engineering in the University 

 of Edinburgh^ which he occupied till his death, teaching with much 

 success. 



In 1859 he began to write upon scientific subjects, encouraged 

 to do so, as he has himself remarked, by Sir William Thomson. His 

 published papers are in all about forty in number. Of these a large 

 proportion deal with questions arising from the science and practice 

 of submarine electrical engineering, and were published within the 

 ten years 1859 to 1869 — a period of the greatest progress in submarine 

 telegraphy. 



Professor Fleeming Jenkin took a very important part in the work 

 ■of the British Association Committee on Electrical Standards, 

 appointed on the suggestion of Sir William Thomson at the Man- 

 chester meeting of 1861, for the purpose of promoting the practical 

 use of Gauss and Weber's system of absolute measurement, by which 

 lasting benefit has been conferred on electric and magnetic science. 

 Jenkin was made Secretary of this Committee ; and, in conjunction 

 with Professor Clerk Maxwell, carried out the most important of the 

 experiments instituted by the Committee. 



Through having been so intimately concerned in the beginnings of 

 ocean telegraphy, Jenkin became associated with Sir William Thomson 

 and Mr. C. P. Varley in the development of the instruments by which 

 the transmission of messages over long submarine cables was for the 

 first time made practicable. During later years he and Sir William 

 Thomson acted as joint engineers for various cable companies, their 

 latest work in that capacity being the Atlantic and other cables of the 

 Commercial Cable Company. 



Por the last two years he was much occupied with a new mode of 

 electric locomotion, a very remarkable invention of his own, to which 

 he gave the name of " Telpherage." He persevered with endless 

 ingenuity in carrying out the numerous and difficult mechanical 

 arrangements essential to the project, up to the Very last days of his 

 work in life. He had completed almost every detail of the realisa- 

 tion of the system which was recently opened for practical working 

 at Grlynde, in Sussex, four months after his death. 



His book on " Magnetism and Electricity," published as one of 

 Longman's elementary series in 1873, marked a new departure in the 

 exposition of electricity, as the first text-book containing a systematic 

 application of the quantitative methods inaugurated by the British 

 Association Committee on Electrical Standards. In 1883 the seventh
