392 Eminent Living Geologiafs — 



la fact, whatever work be has done, whether scientific, educational, 

 or administrative, has always been characterized by a careful 

 observation, a conscientious thoroughness, and an earnest desire to 

 arrive at the truth." 



When Professor Huxley retired from his professorship in the 

 Eoyal College of Science in 1885, he retained the post of Honorary 

 Dean, but many of the duties of the office were undertaken by 

 Professor Judd, who on the death of Huxley in 1895 was made 

 Dean and created a C.B. He was elected a Fellow of the Koyal 

 Society in 1877, and has served twice for periods of two years each 

 on the Council, acting as a Vice-President of the Society in 1902 

 and 1903. In 1887 he was President of the Geological Section of 

 the British Association at the Aberdeen meeting, and some years 

 subsequently had the honorary degree of LL.D. conferred upon him 

 by the University of that city. He has acted for a considerable time 

 as Chairman of the Seismological Committees both of the British 

 Association and the Royal Society, and is Foreign Secretary of the 

 Mineralogical Society. 



While educational, official, and other duties have necessarily 

 limited his opportunities for research during recent years, he has 

 found time for study of materials obtained by boring in the 

 Nile Delta, for work upon the products of the great eruption at 

 Krakatoa, on the rocks brought home from the Ruby district of 

 Burma by Mr. C. Barrington Brown, and especially on the cores and 

 other specimens obtained in the boring in the Coral-reef of Funafuti. 

 Various incidental questions like those of the nature of Sarsens, the 

 materials employed in the building of Stonehenge, the nature of 

 the rocks forming Rockall, with problems arising out of the study 

 of rock-forming minerals, have engaged his attention and formed 

 the subject of numerous papers. Of larger works for students he 

 has written a revised edition of Lyell's Elements under the name 

 of "The Student's Lyell"; "Volcanoes: What they are and what 

 they Teach"; a translation, with introductory notice, of Behren's 

 " Microchemical Analysis"; and critical introductions to Darwin's 

 geological books, one of these having been translated into French 

 by his old friend Professor Renard. 



From the teaching work, which has occupied so much of his time 

 and energies during nearly thirty years, Mr. Judd has now just 

 retired, having reached the age limit. Many hundreds of his students 

 now occupy important teaching posts or are engaged in the geological 

 surveys of our own country, the Colonies, India, and Egypt, while 

 still more are engaged in mining and metallurgical work in all parts 

 of the globe. 



One of his old Assistants who knows his methods of teaching, and 

 has gone through the work of the Royal College of Science with 

 him, writes : — 



"As a teacher of geology Professor Judd holds a position of the 

 highest distinction. The courses of instruction designed and 

 gradually evolved by him have long been regarded as among the 

 most perfect and complete of their kind. He was one of the very
