appointed I^aturalist on the Surveying Yoyage of H. M. ship *'Fly,"he 
had an opportunity of applying his rare powers of observation to the 
phenomena of IN'ature in the Tropics, and of adding considerably to the 
then existing amount of knowledge on the Coral Eeefs of the Korth- 
East coast of Australia. He published in 1847 a work giving an 
account of this voyage. On his return he was employed in the English 
Geological Survey, and produced an excellent Monograph on the 
South Staffordshire Coal-fields. This work gave the author a high 
rank among geologists, and led to his appointment as a member of 
the Jevons Coal Commission. When, in 1851, Professor Oldham was 
placed at the head of the Geological Survey of India, Mr. Jukes was 
chosen to fill his place as Local Director of the Survey of Ireland. 
When Mr. Jukes came to this country there existed a profound diffe- 
rence of opinion between English and Irish geologists as to the relations 
between the Devonian and Carboniferous Rocks — the English geologists 
interpreting Ireland by the phenomena exhibited in a complex form and 
on a narrow scale by the rocks of Devonshire, while the Irish geolo- 
gists insisted upon the Irish Rocks as being the true type of the entire Car- 
boniferous system, and held that Devonshire, and such other restricted 
areas, must be interpreted from the larger and typical development of 
the Carboniferous series in the South of Ireland. Convinced by his own 
observations, and those of his staff, he became the warmest advocate 
of the views maintained by Irish geologists. He undertook to test 
the correctness of those views by personal observations in Devonshire, 
and his observations confirmed the opinions he had adopted. The re- 
sults, which he published, both separately and in the "Journal of the 
Geological Society of Ireland," were cordially received by men of science, 
and the doctrine he maintained will, no doubt, ultimately be universally 
accepted. Mr. Jukes was marked by independence of character, great 
candour of mind, and the most sensitive honour. His'social qualities 
won for him the warm attachment of his friends. His "Student's Manual 
of Geology," which has passed through several editions, is regarded as 
one of the best elementary treatises on that Science. He was, for some 
time, a Member of the Council of the Academy ; and the followiDg 
Papers from his pen appear in our " Proceedings and Transactions " : — 
" On the Peak of Teneriffe," in Yol. YI. ; "On the Lower Palaeozoic 
Rocks of the Sonth-East of Ireland; " and " On the Coexistence of the 
Human Race and Extinct Animals," in Yol. YIL; "On the Flint Im- 
plements found at St. Acheul," in Yol. Yill.
