his father had a printfield on the hanks of the Kelvin. His family 
originally belonged to Strathendrick, which was, along with the 
Lennox, the chief seat of their name. Mr Euing conceived the 
latter (which he traced back to Domesday Book) to be connected 
with Eugenius, and was somewhat particular as to its being correctly 
spelt with a u. His grandfather settled in Glasgow about 1740, 
and was a magistrate of the city in 1767. His father went to the 
West Indies in 1799, and died there; whereupon Mr Euing, who 
was an only child, was left to the charge of his mother, and of his 
uncle, Archibald Smith of Jordanhill. This relationship laid the 
foundation of the close friendship that subsisted between Mr Euing 
and his cousins, Mr James Smith of Jordanhill, F.R.S.L. & E., 
and Mr William Smith of Carbeth-Guthrie (Lord Provost of Glas- 
gow in 1823), during the prolonged lives of all the three. After 
receiving his elementary education at two private schools, Mr 
Euing was sent to the Grammar School, where he had as his class- 
fellows the late William Lockhart of Milton-Lockhart, M.P., his 
own cousin Mr Robertson Reid of Gallo wflat, and other subsequently 
well known citizens of Glasgow, all of whom he survived. He 
entered the University in 1800 at the age of twelve, and attended 
the classes of Professors Richardson, Young, Jardine, and Millar. 
Although an earnest student, he did not complete the regular 
curriculum, but early entered on business in the calendering firm 
of Inglis, Euing, & Co., of which he soon became a partner. In 
1815, in consequence of the work being too great for his delicate 
health (for at this period and down to 1845 he suffered much from 
illness) he retired, and, after acting for some years as a commission 
merchant, he began in 1819 the business of an underwriter and 
insurance broker, in which he continued at the head of the well- 
known firm of William Euing & Co. till the close of his life, 
visiting daily almost to the last his office in the Exchange. 
As a merchant, Mr Euing was held in the highest esteem by all 
who came into contact with him for his intelligence, his soundness 
of judgment, his probity, and stainless honour. He was a large 
shareholder in the unfortunate Western Bank, and its failure in 
1857 brought into play at once his excellent habits of business 
and his cheerfulness of temper. He carefully and promptly arranged 
his own private affairs with a view to the worst, and then, as direct-
