John Horne, 

 F.G.S., F.R.S.E. One of the Senior Geologists on the Staff 

 of the Geological Survey of Scotland. Has been engaged for 

 more than thirty years in the Geological Survey. From 1868 to 

 1876 he personally studied and mapped large areas of the 

 Silurian uplands of Scotland. From 1876 to 1883 he surveyed 

 extensive tracts in the counties of Nairn, Inverness, Banff and 

 Aberdeen. From 1884 till the present time he has taken an 

 important share in the investigation and mapping of the compli- 

 cated geology of the North-West Highlands. In addition to 

 these official researches he has devoted his intervals of holiday 

 to original exploration, and has made important contributions to 

 our knowledge of the glacial and volcanic geology of the 

 Orkney and Shetland Isles. Among his papers are the follow- 

 ing : — " A Sketch of the Geology of the Isle of Man," and the 

 " Post-Pliocene Formation of the Isle of Man " (Edin. Geol. 

 Soc. Trans., ii., 1 174, pp. 323, 329); "The Geology of the 

 Island of Unst " (Edin. Phys. Soc Proc, iv., 1878, p. 274); 

 " The Volcanic History of the Old Red Sandstone Period North 

 of the Grampians" (Glas. Geol. Soc Trans., vii., 1881, p. 77). 

 Most of his investigations have been worked out in conjunction 

 with Mr. B. N. Peach, F. R.S., but the results have been 

 arranged and described by Mr Ilorne. Some of this conjoint 

 work has been of the highest value, both in regard to British 

 geology and to the theoretical treatment of the science. Special 

 reference may be made to the " Report on the Recent Work of 

 the Geological Survey in the North-West Highlands of Scot- 

 land " (Quart, /ourn. Geol. Soc, xliv. , 1888, p. 378), in which 

 the detailed structure of one of the most intricate geological 

 regions in Europe was worked out and illustrated ; to a paper 

 on " The Olenellus-Zone in the North-West Highlands" (ibid., 

 xlviii., 1892, p. 227), which demonstrated the existence and 

 stratigraphical relations of Lower Cambrian Rocks in Scotland ; 

 and to the large volume recently published by the Geographical 

 Survey, on " The Silurian Rocks of Scotland " (p. 749), which 

 gives t-he detailed results of a prolonged and laborious investiga- 

 tion by Messrs. Peach and Horne of the whole Silurian region 

 of southern Scotland. In 1888 was awarded the WoUaston 

 Fund by the Geological Society, and in 1899 received from the 

 same Society, in association with his friend and colleague, Mr. 

 Peach, a duplicate Murchison medal. Received, in 1893, ^^^ 

 Neill medal from the Royal Society of Edinburgh, in recognition 

 of the value of his contributions to Geology. 



Joseph Jackson Lister, 



M.A., F.Z.S. Demonstrator of Comparative Anatomy in the 

 University of Cambridge. Distinguished as a Zoologist. Was 

 NaturaUst on board H.M.S. Egeria in two cruises, one to 

 Christmas Island (Indian Ocean), the fauna of which he was 

 the first to investigate, and another in the Pacific among the 

 Tonga, Union and Phoenix Islands, during which he made him- 

 self well acquainted with the fauna of those islands, and of the 

 Seychelles. His researches on the Foraminifera have thrown 

 important light on the life-history and reproduction of that 

 group. Author of the following papers: — "On the Natural 

 History of Christmas Island in the Indian Ocean " (Proc Zool. 

 Soc, 1888, p. 512) ; "On some Points in the Natural History 

 of Fungia" (Quart. Journ. Micros. Soc, vol. xxix., p. 359) ;
