from the experimental and scientific work of the Committee is
certainly in a large measure due to Jenkin's zeal and perseverance
as secretary; and as editor of the volume of Collected Reports of
the work of the Committee; which extended over eight years; from
1861 till 1869。 The volume of Reports included Jenkin's Cantor
Lectures of January; 1866; 'On Submarine Telegraphy;' through which
the practical applications of the scientific principles for which
he had worked so devotedly for eight years became part of general
knowledge in the engineering profession。
Jenkin's scientific activity continued without abatement to the
end。 For the last two years of his life 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 realisation of the system which was recently opened
for practical working at Glynde; 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 edition was published; after there had already appeared
two foreign editions; one in Italian and the other in German。
His papers on purely engineering subjects; though not numerous; are
interesting and valuable。 Amongst these may be mentioned the
article 'Bridges;' written by him for the ninth edition of the
'Encyclopaedia Britannica;' and afterwards republished as a
separate treatise in 1876; and a paper 'On the Practical
Application of Reciprocal Figures to the Calculation of Strains in
Framework;' read before the Royal Society of Edinburgh; and
published in the 'Transactions' of that Society in 1869。 But
perhaps the most important of all is his paper 'On the Application
of Graphic Methods to the Determination of the Efficiency of
Machinery;' read before the Royal Society of Edinburgh; and
published in the 'Transactions;' vol。 xxviii。 (1876…78); for which
he was awarded the Keith Gold Medal。 This paper was a continuation
of the subject treated in 'Reulaux's Mechanism;' and; recognising
the value of that work; supplied the elements required to
constitute from Reulaux's kinematic system a full machine receiving
energy and doing work。
