plants, and to the study of the reproduction and development of 

 various groups of cryptogams, and also to viviparous reproduction 

 in phanerogams. Nor did he leave unstudied the allied science 

 of zoology, as shown by several articles on the morphology and 

 the physiology of animals. 



The first article published by him of which there is any record 

 appeared in 1837, in Jardine's Magazine of Zoology and Botany », 

 and is entitled, " Remarks on the Reproductive Organs of Pila- 

 /aria globulifera and the Globules of Chara Vulgaris." After 

 that year he published numerous articles in the London Journal of 

 Botany, the Annals and Magazine of Natural History, the Reports 

 and the Transactions of the Edinburgh Botanical Society, and the 

 British Association Reports, and other journals ; but latterly 

 restricted his articles for the most part to the Journal of the 

 Linnean Society. In the latter, of late years, numerous papers by 

 him appeared, dealing chiefly with the Algce of the " Challenger" 

 expedition, but also giving an account of collections of fresh-water 

 Algce from tropical regions. 



A list of his articles, previous to 1873, is contained in the Royal 

 Society's Catalogue of Scientific Papers, and its appendix. 



He published his first paper on Algce in 1844, in the Annals 

 a?id Magazine of Natural History, the title being, " On the Marine 

 Algce of the Vicinity of Aberdeen ; " and at intervals he continued 

 to publish papers on them, as well as on other plants, till 187 1, 

 after which year he restricted his published articles to Algce. He 

 also wrote the botanical appendices to the works of various Arctic 

 travellers, and reported on the Algce of the " Transit of Venus " 

 expeditions. The botanical appendix to Macgillivray's Natural 

 History of Deeside and Braemar was also drawn up by him, and 

 his assistance is also frequently acknowledged in that book by its 

 author. Dr. Dickie's longer works are, A Flora of Aberdeen 

 (1838), The Botanist's Guide to the Counties of Aberdeen, Banff, 

 and Kincardine (i860), and A Flora of Ulster (186 4). In these 

 works are included the results of his personal investigations, and 

 of information supplied to him by various friends and former 

 pupils, whereby he was enabled to give more fully the distribution 

 of the species in the areas treated of. In the first and last- 

 mentioned books he restricts himself to the vascular plants ; but 

 in the Guide he includes the cellular cryptogams also. For the 

 latter he had to depend on his own labours and on information 

 from only one or two friends, hence the lists, though of much 

 interest, are less complete than among the vascular plants, except
