and Mr Coleman’s dry-air mechanical refrigerators were fitted np in 
many steamers. Mr Coleman acquired a modest fortune from his 
invention, and, retiring to Bearsden, near Glasgow, he built a small 
private laboratory in connection with his house, and devoted him- 
self entirely to original investigation. He contributed numerous 
papers to the Philosophical Society of Glasgow, to this Society, to 
the Society of Chemical Industry, and to the Institution of Civil 
Engineers. For many years Mr Coleman suffered from weak health, 
and at length his frail body succumbed to a complication of disorders. 
He was a man of bright and lively intelligence, who took an original 
view of any scientific question to which his mind was directed. 
Although eminently practical as a chemical engineer, he had a great 
regard for the first principles of science, and even for those problems 
in chemistry and physics that are of merely speculative interest to 
most men. Few were more gifted with the power of recognising the 
practical applications of scientific theory, and it was this quality 
of mind that led him to the invention of the machinery for the 
mechanical transference of heat with which his name will always 
he associated.

This distinguished physiologist and ophthalmologist was horn in 
North Brabant on 27th May 1818, and died at Utrecht on 24th 
March 1889. Educated in the Dutch Boy al Hospital for Military 
Medicine and Surgery, he practised for a time as army surgeon in 
Yliessingen and in the Hague ; hut an anatomical and pathological 
investigation on the nervous centres having attracted the attention 
of the authorities, he was soon appointed lecturer on anatomy and 
physiology to the Boyal Military Academy in Leyden. This office 
he held till 1848, when he was appointed professor extraordinary in 
the Medical Faculty of the University of Utrecht; in 1852 he 
became an ordinary professor ; and on the death of Schroeder van 
der Kolk, in 1862, he was called to the chair of physiology. He 
filled this chair till 1889, when he retired in compliance with the 
law of the universities in Holland, by which no professor can occupy 
a chair after attaining his seventieth year. Soon after his retirement 
his health gave way, and he died after a series of apoplectic attacks.
