Ki PEOCEEDINGS OF THE GEOLOGICAL SOCIETY. [vol. lxxiv, 



William Bullock Clark was born at Brattleboro (Vermont), 

 in 1860. His tastes early inclined him to Geology, and in par- 

 ticular to Palaeontology, and he studied under Zittel at Munich, 

 where he graduated in 1887. From there he went to Johns 

 Hopkins University, Baltimore, where he was subsequently 

 appointed Professor of Geolog}'. He was the author of numerous 

 reports and papers, dealing; mainly with the geology and palaeon- 

 tology of the Cretaceous and Tertiary formations in the Atlantic 

 States. After contributing to the publications of the Geological 

 Survey of New Jersey and of the United States Geological Survey, 

 he was in 1897 appointed State Geologist on the newly established 

 Geological Survey of Maryland. He was interested also in 

 meteorolo^r and climatolo^v, and held the office of Director of the 

 Marvland State Weather Office. His services to sreolosrv were 

 recognized by this Society when he was elected a Foreign Corre- 

 spondent in 1904. He died on July 27th, 1917, aged 57. 



A link with the past is severed by the death of Thomas 

 McKenxt Hughes, for forty-four years Woodwardian Professor 

 at Cambridge. Since his predecessor, Adam Sedgwick, was elected 

 in 1818, the two tenures covered nearly a century, a period which 

 has seen the whole growth of modern Geology. Born at Aberyst- 

 with in December, 1832, Hughes was the son of the Rev. Joshua 

 Hughes, afterwards well known as Bishop of St. Asaph, and he 

 was named after his maternal grandfather, Sir Thomas McKenny, 

 Bart., who had taken a prominent part in Catholic Emancipation 

 in Ireland. From school at Leamington and Llandovery he went 

 to Trinity College, Cambridge, and, like many of his contemporaries, 

 came under the influence of Sedgwick. After taking his degree, he 

 was attached for a time to the British Consulate at Home during 

 the eventful days of 1860-61. He seems at this time to have 

 contemplated a diplomatic career, but the attractions of Geology 

 prevailed, and he returned to England to join the Geological Survey 

 under Murchison. He was engaged first in the South-Eastern 

 Counties, and afterwards in Westmorland and on the borders of 

 the West Biding. 



Upon the death of Sedgwick in 1873 he became a candidate for 

 the vacant Chair. The election was at that time in the hands of 

 the Electoral Roll, and the choice fell upon Hughes, for whom the 

 duties of his office became thenceforward the work of his life.
