to Scotland, he acted as house-surgeon to our eminent countryman 
Mr Liston, in the Infirmary of Edinburgh, and in the hospital of 
University College, London. In 1837 Dr Duncan settled in Edin- 
burgh as a medical practitioner, where he rose to great eminence, 
and enjoyed the largest general practice. He was surgeon to the 
Royal Infirmary for many years, and in that capacity delivered 
lectures on clinical surgery. He was elected a Fellow of this Society 
in 1858 ; but though he was the author of many valuable papers 
in the medical journals, he did not contribute to our Transactions. 
Dr Duncan was in the habit of spending a few weeks in the 
country every autumn, as a relaxation from the duties of his exten- 
sive practice. In July 1866 he went to the Continent with his 
wife and family, committing to his son the charge of his patients 
in Edinburgh. During a few days’ residence in Paris, when the 
cholera prevailed, he seems to have imbibed the germs of that fatal 
disease. On the 12th of August he was attacked with diarrhoea, 
which so completely yielded to its usual treatment that he went 
next day to Orleans. From Orleans he went to Tours, where, on 
the 15th, he was attacked with cholera, which proved fatal on the 
16th August, in the 56th year of his age. 
John Cay, of North Charlton, in the county of Northumber- 
land, was born in Edinburgh on the 31st August 1790, and was 
the eldest son of Mr Robert Hodshon Kay, of North Charlton, 
Judge Admiral of Scotland. He was educated at the High School 
and University of Edinburgh, and was admitted into the Faculty 
of Advocates in 1812. In 1822 he w r as appointed Sheriff of the 
county of Linlithgow, an office which he held for forty-three 
years, and the duties of which, as a sound lawyer and a judicious 
judge, he discharged with great credit to himself and great satis- 
faction to the public. Mr Cay took a great interest in the literary 
and scientific institutions of Edinburgh. He was elected a Fellow 
of the Royal Society in 1821, and contributed to its Transactions a 
short notice of a bronze spear-head found on his property in 
Northumberland. He was also a Member of the Royal Scottish 
Society of Arts, and was one of the annual Presidents of that im- 
portant institution. Mr Cay was the author of a work on “ The Re- 
form Act,” and of two small pamphlets-— one an “ Analysis of the
