as the upper part of the Mountain Limestone split up by shales and 

 sandstones." 



In all his notes published by the Geological Survey we find 

 careful attention paid to the work of previous observers, and many 

 acute observations on the facts and phenomena that came before him. 



It was while serving as an Assistant Geologist on the Geological 

 Survey that the Chair of Geology in Cambridge became vacant 

 by the death, in his 88th year, of the illustrious Professor Adam 

 Sedgwick, on the 27th January, 187o, after occupying that position 

 for 55 years. 



By Statute of the University, the appointment must take place 

 within one month from the vacancy being declared, so that on the 

 20th February, 1873, the Heads of Houses, Professors, University 

 Examiners, and resident members of the Senate proceeded to elect 

 a successor, no fewer than nine candidates having oftered themselves 

 for the post. Most of these, however, withdrew without going to the 

 poll, while other candidates early retired from the contest, which 

 finally resulted in the election of Mr. Hughes by a small majority 

 over Professor Bonney. 



Both before and after his election to the chair. Professor Hughes 

 was intimately associated with the late Sir Charles Lyell, with 

 whom he made several foreign and British tours. Lyell frequently 

 mentions his friend — " Mr. T. M'K. Hughes, noio Woodwardiau 

 Professor at Cambridge" — in the fourth edition of his " Antiquity of 

 Man," when, in the Spring of 1872, they visited together the cave of 

 Aurignao and the caverns of Dordogne. 



Asa lecturer Pi'o lessor Hughes is extremely fluent and clear in his 

 deliverj', and he makes excellent use of the chalk and blackboard to 

 aid his demonstrations. He is also a most popular man with his 

 students and at the meetings of his fellow-workers at the Geological 

 Society of London. 



The remarkable feature of Professor Hughes' work in Cambridge 

 has been the large number of men of mark who have studied under 

 him, and also the very strong list of graduates who have joined the 

 teaching stafi' in what is now justly recognised as " tlie Cambridge 

 School of Geology." 



We recall with pleasure some of these who have taken 

 distinguished places in the world, and a few who have already ended 

 their work well : —
