these works he enumerates the vascular plants of the districts treated 

 of, and gives much information as to their localities and altitudinal 

 range, and in the "Botanist's Guide," he includes the cellular 

 cryptogams so far as known to himself, and of the marine Alga? in 

 particular he gives a very complete list. 



Dr. Dickie did not confine his studies to botany, but wrote also 

 cn zoology, treating chiefly of morphology. In conjunction with Dr. 

 McCosh he was author of "Typical Forms and Special Ends in 

 Creation," to which he contributed those parts that relate to botany, 

 zoology, physiology, geology, and physical geography. In this work 

 the authors seek to indicate the evidences of design in the universe 

 discoverable alike in the general principles that prevail throughout, and 

 in the special adaptations of organised beings to their environments. 



In private life Dr. Dickie was much esteemed. He was ever ready 

 to aid those in need of assistance in every way in his power ; and as 

 professor gained the respect and esteem of his students, not a few of 

 whom owe their success in after life to his devotion to their culture 

 and future careers. 



Dr. Dickie's constitution was never robust; he overtaxed his 

 strength when young, and in middle life by his exertions in the field 

 as an observer and collector, and he suffered from chronic deafness. 

 During an excursion in Braemar with his students, in 1861, he 

 exposed himself for several days of very severe weather, which 

 resulted in bronchitis and its complications, from which he never 

 entirely recovered. This and increasing deafness latterly cut him off 

 from personal communication with strangers, but his correspondence 

 and his interest in scientific pursuits were never relaxed. In the 

 early part of this year he had a severe attack of bronchitis, which 

 after recoveries and relapses carried him off on the loth July, 1882. 



Dr. Dickie married, in 1856, Miss Agnes Low, of Aberdeen, who 

 survives him, and by whom he had six children. 



Ronald Caaipbell Gunx was an ardent naturalist, and to his 

 exertions far more than to those of any others we are indebted for a 

 knowledge of the botany and zoology of his adopted colony, 

 Tasmania. 



Mr. Gunn, the son of an officer in the army, was born at Cape Town 

 on April 1th, 1808, and was brought thence to Bourbon, at the 

 capture of which place his father assisted. Until 1816 he accom- 

 panied his father's regiment to the Mauritius, the West Indies, and 

 Scotland, where he resided for eight years. His name was placed on 

 the Commander-in-Chief's list for a commission in the army ; this, 

 however, he never received : but an appointment in the department 

 of the Royal Engineers at Barbadoes was given him, which he held 

 till 18*29, when he emigrated to Tasmania. Here he became
