adhesion to botany as an occupation for life. The next (in 
1823) was Dr. (afterwards Sir John) Richardson, R.N., the 
companion of Franklin in his Arctic expeditions, through 
whom my father was made known to the Lords of the 
Admiralty, the Directors of the Hudson’s Bay Company, and 
the chiefs of the Colonial Office, thus becoming the recipient 
of many herbaria made by the officers of these departments, 
and the author of works published under their authority. 
It further led to his being asked to recommend young medical 
men fond of natural history, from amongst his pupils especially,

the ‘ Botany of Beechey’s Voyage,’ ‘ Contributions towards 
the Flora of South America and the Pacific Islands,’ and the 
sixth and seventh editions of ‘ The British Flora.’ As 
Dr. Arnott, LL.D., he succeeded Dr. Balfour in the botanical 
Chair of Glasgow, and died in 1868. 
In 1827 my father’s correspondence commenced with 
W. Wilson, of Warrington, who paid many visits, sedulously 
studying the mosses of the herbarium, and exploring the 
Highland mountains, sometimes joining in the botanical class 
excursions. Latterly he volunteered a revision of the whole 
collection of Musci in the herbarium, thereby adding very
