diterraneau till 1810, and during this period shared in a gallant 

 action with the Toulon fleet. He afterwards proceeded to the 

 South- African station, on his return from which he was promoted 

 to the rank of Commander, and on the 12th May 1827 was ap- 

 pointed Captain of the * Prince Regent,' 120 guns. In 1858 he be- 

 came Admiral. 



During many years Admiral Jones sat in Parliament for the 

 county of Londonderry. 



In the world of science, notwithstanding that he had pub- 

 lished scarcely anything, he occupied a very high place as a 

 lichenologist in the estimation of those interested iu that branch 

 of Botany. Amongst Britisl^ichenologists few, or perhaps none, 

 exceeded him in accurate and precise knowledge, derived from 

 ],ong-continued, assiduous, and original observation, which he 

 allowed nothing to interrupt, even up to tlie very day of his 

 death. 



I am not acquainted with any paper from his pen except a 

 *' Report on the progress made in collecting the Irish Lichens," 

 whiph accompanied the presentation to the Natural- History 

 Society of Dublin of a complete series of specimens of tliose 

 hitherto collected — and some observations on the " Discovery of 

 spiral fibres in the Thallus of JEvernia prunastri,'" which were 

 published in the ' Dublin Quarterly Journal of Science.' He is 

 also cited by Van Krempelhuber as the discoverer of several rare 

 species of Irish and Scotch lichens ; but the descriptions, I appre- 

 hend, of these were perhaps only in MS., as Admiral Jones main- 

 tained an active correspondence with foreign lichenologists. His 

 scientific reputation, therefore, will rest more upon the important 

 and valuable collections he made, which have been presented to 

 the Eoyal Dublin Society, and which, with the exception of the 

 collection of Mr. Carroll, of Cork, constitute the most complete 

 collection of Irish lichens extant, than upon his published writings. 

 The utility of these collections is much enhanced by their being 

 accompanied with catalogues, which are all written up correctly, 

 and thus render the specimens at once available for study. 



Admiral Jones was a man of indoipitable energy and industry 

 in the pursuit of his favourite subject, and in the prosecution of 

 his researches not unfrequently exposed himself to risk of fatigue 

 and danger not usually incurred by a septuagenarian. A striking 

 instance of his remarkable powers of endurance is recorded in the 

 account of the following circumstance. Aboi,it six years before
