the Board of Manufactures. This appointment he held until 30th 
September 1858, when he was placed in retirement by the Treasury 
in order to carry into effect the affiliation of the school with the 
Science and Art Department of South Kensington. His connection 
with this school, therefore, extended over a period of twelve years 
(set. 37-49). 
On 3d March 1851 he was elected a Fellow of the Royal Society, 
to which he continued to belong until his death. 
On 16th June 1859 (set. 50) he married Jane Fordyce, eldest 
daughter of the late James Rose, W.S. Soon after his marriage he 
commenced the practice of photography as a profession, and applied 
the process of carbon-printing, with great success, to the illustration 
of books. 
In 1870 (set. 61) his health, which had previously been very 
good, was severely shaken by blood poisoning from bichromate of 
potash used in the process of carbon printing. 
In 1872, when smallpox was prevalent in Edinburgh, he caught 
the infection from one of his assistants, and had a very severe attack 
of that disease. In the autumn of 1877, while on a visit to London, 
he had a very serious attack of typhoid fever, and never thoroughly 
recovered from the prostration of strength which followed the fever. 
The long-continued cold of the winter of 1878-79 tried him greatly.. 
An attack of inflammation, brought on by a cold caught in January 
1879, was the cause of his death, which took place at Dean-bank 
House on the 26th day of that month. 
Such were the incidents in the uneventful but by no means un- 
worthy life of Elmslie William Dallas. As regards pecuniary results 
it was a life of unsuccessful effort ; but as regards the spirit in 
which the work of his life was done, and the intrinsic value and 
perfection of that work, E. W. Dallas’s efforts to do well and 
thoroughly things worthy to be done, accomplished much that was 
admirable, in a manner that was most instructive and exemplary 
to all who had opportunities of observing the wealth of earnest lucid 
thought and the patient skilfulness of hand with which he worked 
out his results. 
On 2d February, the Sunday following his funeral, the Rev. 
John M ‘Mur trie, speaking from the pulpit of St Bernard’s, in which 
church Mr Dallas had been for upwards of ten years an elder,
