a considerable amount of hornblende, chlorite, or epidote." Epidiorite, 

 hornblende schist, and gneiss, and less altered igneous rocks of many 

 kinds, together with sundry glacial drifts, alluvial deposits and peat, 

 make up the table of formations. The memoir is well illustrated by 

 effective pictorial views, but it is stiff reading for the pedestrian, 

 who, rambling along the Pass of Killiecrankie, over the heights of 

 Ben Vrackie, on the shores of Loch Eannoch, or over Carn Mairg, 

 wishes to gather a general notion of what geology teaches. 



IV. Ireland. — Tlie Geology of the Country around Belfast, By 

 G. W. Lamplugh, F.G.S., J. E. Kilroe, A. McHenry, M.R.I.A., 

 H. J. Seymour, B.A., W. B. Wright, B.A., and H. B. Muff,B.A. 

 pp. 166. (1904. Price 3s.) 



This is an explanation of the special one inch map of Belfast, 

 colour-printed, with Drifts, and it is accompanied by some interesting 

 pictorial views of the Cave Hill quarries (Chalk overlain by basaltic 

 lavas), of the Ordovician rocks on the coast at Carnalea, and other 

 geological features. The account of the Paleozoic and Mesozoic 

 rocks and of the Tertiary volcanic rocks is mainly compiled from 

 previoiTS Survey memoirs and the published works of later observers. 

 The chief work of the Survey was in the detailed mapping of the 

 Drifts, and a very excellent description of these superficial deposits 

 has been drawn up by Mr. Lamplugh and his colleagues. They 

 point out that the chief features are pre-Glacial ; the later modi- 

 fications being mainly due to the partial infilling of some depressions 

 and the carving out of narrow gorges by post-Glacial drainage. 

 During the Glacial episode the whole area was buried under au 

 ice-sheet, and therefore protected from direct subaerial erosion, 

 undergoing only the more partial and probably much less rapid 

 waste from the passage of the slowly moving mass. Water supply, 

 agricultural geology, and other economic matters are dealt with in 

 this Memoir,

LONG before the discovery of any i-ecords of man inscribed or 

 carved on bones, or painted on the walls of caves and rocks, 

 on temples, tombs, or papyri, we may feel quite certain that the 

 earliest representatives of our race had been directed to the open 

 book of Nature, and that plants and animals were the first object- 

 lessons which they studied, Adam, indeed, is credited by his 

 historian with the authorship of the earliest "Index Animalium," 

 but no copy survives. Solomon at a later date is recorded to have 

 been a botanist of wide knowledge, but his learning was oral and 

 traditional and is lost to us.
