1920-21.] 
leaving school, entered the writing chambers of Messrs Dundas & Wilson, 
as an apprentice. He was admitted a Writer to the Signet in 1871, and 
a few years later became a partner. In 1913 he retired from business. 
On the formation of the present Government he returned for two years 
to the post of Crown Agent, which he had held from 1895-1905. Dr 
Dundas was for many years a Director of the Standard Life Assurance 
Company, and was also on the Board of the Edinburgh Academy. In recent 
years he rendered admirable service as one of the Carnegie Trustees, and 
in 1914 received the degree of LL.D., from the University of Edinburgh. 
He stood in the direct line of the best Scottish legal traditions, and his 
place will be difficult to fill. 
Dr Dundas, who was interested in the study of the higher mathematics, 
was elected a Fellow of the Society in 1919, and died at Edinburgh on 9th 
July 1921. 
Gatehouse, Tom Ernest, A.M.Inst.C.E., MJ.Mech.E., M.I.E.E., was 
born in 1854 at Norwich, in Norfolk. He was the son of Mr Tom 
Gatehouse, a mechanical engineer ; naturally, therefore, he had a bent 
towards engineering as a profession, and about 1870 he became a pupil 
of Robert Sabine, one of the most eminent and able pioneers in the 
electrical industry. Later he was associated with Sir Charles Wheatstone 
and Sir Samuel Canning, foremost exponents of the art of telegraphy on 
land and by submarine cable. Amongst the various undertakings with 
which he was closely connected were the first electric lighting of Aldgate 
Station with Lontin arc lamps, and the development of the Werdermann 
arc lamp and the Gramme dynamo; in regard to the Lontin lamp he 
patented an improvement. He was also interested in the development 
of the telephone and experimented with a view to its improvement. The 
introduction of the incandescent lamp, however, indirectly proved to be 
a turning point in the career of Mr Gatehouse, who invented a device 
(afterwards re-invented in connection with the Nernst lamp) for the 
patent rights of which he received a substantial sum. About this time 
his fellow-pupil under Sabine, Mr H. R. Kempe (subsequently Electrician 
to the Post Office), had become associated with Mr H. Alabaster, proprietor 
of the Telegraphic Journal and Electrical Review, and invited Mr 
Gatehouse to throw in his lot with them. Mr Gatehouse assumed the 
office of editor in 1881. In recent years, owing to failing health, he has 
not taken a very active part in the production of the Electrical Review. 
Mr Gatehouse was elected to the Fellowship of the Society in 1899, 
and died in London on Thursday 31st March 1921.
