THE Brrps’ Nest Isuanps.—The records of the Geological 
Survey of India (vol. xxi. pt. 1) have some information concerning 
the remarkable group of islands called by the Burman’s Ye-ei-gnet 
thaik or Seabirds’ Nests. These islands consist of six marble rocks 
to the southeast of Dumel Island at the southern extremity of

steep declivity on the East and a gradually sloping table land on 
the West. The Eastern and smaller part of the Transvaal consists 
mainly of a series of low granite mountains. A series of parallel 
chains extend east and west through the country and divide it into
