Obituary — Mr. J. Beete Jukes. 43 1 



he proceeded to St. John's College, Cambridge, where he took his 

 degree of B.A. in 1836. It was here, we believe, that, under the 

 teaching of Professor Sedgwick (whom he ever regarded with feel- 

 ings of veneration, and with whom he was a favourite pupil), he 

 imbibed a love for his chosen science, which he soon after applied 

 in a Geological Survey of Charnwood Forest, in Leicestershire, and 

 the surrounding country. 



Early in 1839 he was appointed Geological Surveyor of the Colony 

 of Newfoundland, and has recorded the results of his labours in a 

 work on the Geology of that country, accompanied by a map and 

 illustrations. Shortly after his return to England in 1841, Mr. 

 Jukes was appointed by the Admiralty to the post of Naturalist on 

 board H. M. Ship " Fly," commanded by Captain E. P. Blackwood, 

 E.N., for the Survey of the Coast of Australia and New Guinea, 

 and had opportunities, which he turned to good account in after life, 

 of becoming acquainted with the nature and mode of formation of 

 Coral Eeefs, and their relations to the limestones of former Geological 

 periods. The results of this exploration are detailed in " The Voyage 

 of H. M. Ship Fly." The good ship returned to England in June, 

 1846, and in September of that year Mr. Jukes was appointed to the 

 staff of the Geological Survey of Great Britain, of which Professor 

 A. C. Eamsay was Director, and Sir H. T. De la Beche, Director- 

 General. At that time the Survey was being carried on in North 

 Wales, and Mr. Jukes was associated with Eamsay, Aveline, and the 

 late Mr. Salter, as Palfeontologist, in the production of those maps 

 and sections which have justly drawn forth the admiration of all 

 who have studied them, for the minuteness and fidelity with which 

 they illustrate the structure of a broken and mountainous country, 

 complicated by numerous flexures, the outflow of trap-rocks, and 

 often traversed by enormous dislocations. On the completion of the 

 Survey in Wales, Mr. Jukes undertook that of the South Stafford- 

 shire Coal-field and the adjacent country. His memoir on the 

 Geology of the South Staffordshire Coal-field is one of the most 

 valuable contributions to the literature of the Carboniferous Eocks 

 of England. In 1850 he was appointed by Sir E. I. Murchison to 

 the post of Director of the Geological Survey of Ireland, vacant on 

 the appointment of Professor Oldham to the Survey of India ; and in 

 1854 to the Lectureship of Geology in the Eoyal College of Science 

 in Dublin, under Sir Eobert Kane. 



In his capacity of Director, Mr. Jukes applied himself with all 

 his energies to the duties before him ; and with the assistance of (till 

 recentl}'^) a small staff of Surveyors — of whom the lamented JMr. Du 

 Noyer and Messrs. G. H. Kinahan, F. J. Foot, J. O'Kelly, E. G. 

 Symes, and W. H. Baily, as Palaeontologist, were the principal — 

 he completed the Survey of about one-half the superficial area of 

 Ireland, together with the editing and partial authorship of about 

 42 explanatory Memoirs on the Geology of the countr3^ 



During this period Mr. Jukes did not neglect investigations of a 

 more private character, tending to elucidate the structure and the 

 relations of the rooks of England and Ireland. His researches in
