shore-cliff opposite Imaohar, two miles north of Dougrie, Arran. 

 Plates iii and vi illustrate ' pillowy ' structures in Arenig and 

 Carboniferous lavas in Arran. Plates iv and v illustrate uncon- 

 formability in Upper Old Eed Sandstone and Lower Carboniferous 

 rocks. The other plates illustrate false bedding in the New Red 

 Sandstone, jointing in granite, a Tertiary dolerite dyke traversing 

 New Eed Sandstone, moraines in Glen Cloy, and a landslip. 



This is a very full and interesting memoir, and contains, as will 

 be seen from the title and introduction, contributions by many 

 writers upon a great variety of subjects, although igneous and 

 volcanic rocks and their microscopic structure occupy a large share 

 of its pages. The appendices comprise : (1) Palaeontology, by 

 B. N. Peach, F.R.S. ; (2) Petrography, by H. Kynaston and 

 H. J. Seymour ; (3) Bibliography. 



The list of fossils have been prepared by Mr. B. N. Peach, 

 Dr. C. B. Crampton, Dr. Traquair, Mr. Kidston, Dr. Wheelton Hind, 

 Mr. E. T. Newton, and Mr. Tait. An index appropriately completes 

 this very useful memoir on a most difficult and complex country, 

 but one, upon which many geologists have expended their best 

 energies to unravel and explore, from the days of Pennant (1794) 

 and Hutton (1795) to Sir A. C. Eamsay, who made a model of the 

 Island of Arran (in 1840-41), James Nicol (1852), Sir A. Geikie 

 (1873 and 1897), and Wm. Gunn (1901-1903).

KOEEA is an Asiatic kingdom, consisting mainly of a peninsula 

 lying to the north-east of China, between 34° and 43° N. lat. 

 and 124° and 131° E. long,, being 600 miles from north to south 

 and 135 miles from east to west, with an area of about 80,000 square 

 miles. Its coastline is roughly estimated at 1,740 miles, and its 

 size is slightly under that of Great Britain, with a population of 

 10,528,937. 



" Korea," says Professor Koto, " is the Italy of Eastern Asia. It 

 stretches out from the main body of Manchuria in a southerly 

 direction between the citZ de sac of the Yellow Sea and the Sea of 

 Japan, both being fringing seas, as Italy projects between the 

 Adriatic and the Mediterranean. 



"On the north and north-west the Korean peninsula is bounded 

 by a well-defined topographic feature, the equatorial range of 

 Chyang-paik-san, and a southerly lying basin drained by the 

 Amnok-Gang^ and the Tu-man-Gang. 



1 This is the Ya-lu-Kiang of the Chinese and signifies the duck-green river, from 

 some resemhlance in the colour of the river water to that of a duck's neck. Gang or 

 katiff signifies in the Korean language ' lai-ge,' and clihgon muloi' nai, 'small ' streams..
