varieties, found mainly by himself in their native habitats. 

 His energetic business habits and sterling character commended 

 him for office, and he was elected a Member of Council in 

 September, 1881. In this capacity his services were so much 

 appreciated that on the Treasurership becoming vacant in 1881 

 he was unanimously elected to that office, which he held until 

 his death on 28th December, 1885. Although, to a stranger, 

 Mr. Duff may at first have appeared somewhat retiring, this 

 apparent reserve was found to disappear on a better acquaint- 

 ance ; and his straightforward manner, keen sense of honour, 

 and warm affections, endeared him to all who were privileged 

 with his friendship. In him the Society has lost a warm 

 friend and an efficient office-bearer. 



Mr. John Murray, Challenger Expedition Office, Edinburgh, 

 was elected an Honorary Member. 



Rev. James Fordyce, Bishopbriggs, and Mr. Adam Murdoch, 

 174: Garscube Road, were elected Ordinary Members.
