seven years, with. Mr H. C. Forde for general and telegraphic 
engineering. In the same year he acted as second in command 
nnder Sir William Thomson at the establishment of the British 
Association Committee on electrical standards. Of this committee 
he was appointed secretary, and he wrote their reports for several 
years. He also carried out most of the committee’s important 
experiments in conjunction with Clerk Maxwell and others. He 
was juror for Physical Apparatus at the 1862 Exhibition, and was 
named Reporter for Electrical Apparatus. In 1865 the late 
C. F. Yarley joined Sir William Thomson and Fleeming Jenkin in 
an agreement to work at the development of the signalling apparatus 
through long submarine cables already referred to. The apparatus 
devised by the three inventors was used by all the great companies, 
and Jenkin displayed a remarkable business faculty in the commercial 
management of the patent. In this same year Jenkin was elected 
a Fellow of the Royal Society, and in 1866 he was appointed 
Professor of Engineering at University College, London. In 1868 
he dissolved partnership with Mr Forde, and resigned his post at 
University College, in order to accept the Chair of Engineering in 
Edinburgh University, which chair he filled until his death. After 
accepting this post he entered into a new partnership with Sir 
William Thomson, under the provisions of which Sir William and 
he acted as joint engineers to various submarine cable companies. 
Among the lines which were laid under their direction were those 
of the Western and Brazilian Telegraph Company, the Platino- 
Brazileien Telegraph Company, the West Indian and Panama 
Telegraph Company, and the Mackay-Bennett or Commercial Cable 
Company. In 1871 Fleeming Jenkin was President of the 
Mechanical Section of the British Association, which met that year 
at Edinburgh; and in 1873 he went to Brazil in the interests of the 
Western and Brazilian Telegraph Company. In 1877, in a lecture 
at Edinburgh given for the Edinburgh Philosophical Institution, he 
took occasion to propose the establishment of a Sanitary Protection 
Association. In consequence the Edinburgh Sanitary Protection 
Association was started, and succeeded so well that its example has 
since been followed in many parts both of Great Britain and of the 
United States. To most of these associations in Great Britain 
Fleeming Jenkin was consulting engineer. At the Paris Exhibi-
