﻿Vol. 64.] ANNIVERSAKY ADDRESS OF THE PRESIDENT. Ixiii 



Ey the death of Carl Ludole Griesbach another former member 

 of the Indian Geological Survey has been removed from our 

 membership. He came of an old Hanoverian family. His grand- 

 father settled in England in the reign of George III., and his father 

 remained a British subject. He himself was born in Yienna on 

 December 11th, 1847, and was educated at the University there. 

 Having shown an aptitude for geological pursuits, he for a time 

 obtained employment on the Austrian Geological Survey. In 

 1869-70 he was engaged on a German scientific expedition to 

 Portuguese East Africa. Before leaving that region he had collected 

 materials for an account of the geology of Natal, which was read 

 before this Society in December 1870. Therein he published (1 871) ^ 

 a geological map of the Colony, together with figures and descrip- 

 tions of some new mollusca from the Izinhluzabalungu deposits of 

 Cretaceous age. In 1878 he was appointed an Assistant Superin- 

 tendent on the Geological Survey of India ; he became Director in 

 1894, and retired in 1903. During his service in India he was 

 employed in 1886 on the Afghan Boundary Commission, and was 

 created a Companion of the Order of the Indian Empire in recog- 

 nition of his services. His most important work was his * Memoir 

 on the Geology of the Central Himalayas,' published by the Indian 

 Geological Survey in 1891. He was elected a Eellow of this 

 Society in 1874.^ 



Theodore W. H. Hughes, a third retired member of the Indian 

 Geological Survey, has also been removed from our midst. He was 

 educated at the Hoyal School of Mines (1859-62), of which he 

 became an Associate. Joining the Geological Survey of India in 

 1862, at the age of 19, he was first employed for six years in sur- 

 veying the smaller coal-fields of Bengal and Chota Nagpur ; and 

 he prepared memoirs on a number of them, so that he became a 

 recognized authority on the Gondwana coal-bearing rocks of India. 

 During the next ten years he was employed in enquiries in regard 

 to coal and iron in various parts of the country. It was as the 

 result of his investigations that an extensive colliery in South 

 Eewah was discovered and opened up. So valuable had his expe- 

 rience become in reference to mineral fields that his services were
